MANUAL
ANSUL
This manual is intended for use with ANSUL®R-102™
Restaurant Fire Suppression Systems.
Those who install, operate, recharge, or maintain these fire sup-
pression systems should read this entire manual. Specific sec-
tions will be of particular interest depending upon one’s
responsibilities.
Design, installation, recharge, and maintenance of the system
must conform to the limitations detailed in this manual and per-
formed by an individual who attended an ANSUL training pro-
gram and became trained to install, recharge, design, and main-
tain the ANSULsystem.
Fire suppression systems are mechanical devices. They need
periodic care. Maintenance is a vital step in the performance of
your fire suppression system. As such it must be performed in
accordance with NFPA 96 (Standard for the Installation of
Equipment for the Removal of Smoke and Grease-Laden Vapors
from Commercial Cooking Equipment) and NFPA17A(Standard
on Wet Chemical Extinguishing Systems) by an authorized
ANSULdistributor. To provide maximum assurance that the fire
suppression system will operate effectively and safely, mainte-
nance must be conducted at six-month intervals, or earlier if the
situation dictates. Twelve-year maintenance must include agent
tank hydrostatic testing.

DESIGN AND APPLICATION
The ANSUL R-102 Restaurant Fire Suppression System is
designed to provide fire protection for restaurant cooking appli-
ances, hoods, and ducts.It is a pre-engineered group of mechan-
ical and electrical components for installation by an authorized
ANSUL distributor.The basic system consists of an ANSUL
AUTOMAN regulated release assembly which includes a regulat-
ed release mechanism and a liquid agent storage tank housed
within a single enclosure.Nozzles, detectors, cartridges, liquid
agent, fusible links, pulley tees, and pulley elbows are supplied in
separate packages in the quantities needed for each fire suppres-
sion system arrangement.
The system provides automatic actuation;or it can be actuated
manually through a remote manual pull station.The system is also
capable of shutting down appliances at system actuation.For
appliance shutdown requirements, refer to the current version of
NFPA 17A, “Standard For Wet Chemical Extinguishing Systems,”
and NFPA 96, “Standard For Ventilation Control and Fire
Protection of Commercial Cooking Operations.”
Additional equipment includes:remote manual pull station,
mechanical and electrical gas valves, and electrical switches for
automatic equipment and gas line shut-off.Accessories can be
added, such as alarms, warning lights, etc., to installations where
required.
The R-102 system suppresses fire by spraying the plenum area,
the filters, cooking surfaces, and the exhaust duct system with a
predetermined flow rate of ANSULEX Low pH Liquid Fire
Suppressant.When the liquid agent is discharged onto a cooking
appliance fire, it cools the grease surface, and reacts with the hot
grease (saponification) forming a layer of soap-like foam on the
surface of the fat.This layer acts as insulation between the hot
grease and the atmosphere, thus helping to prevent the escape of
combustible vapors.
Exhaust fans in the ventilating system should be left on.The forced
draft of these fans assists the movement of the liquid agent
through the ventilating system, thus aiding in the fire suppression
process.These fans also provide a cooling effect in the plenum
and duct after the fire suppression system has been discharged.
The system is UL listed with or without fan operation.
Make up or supply air fans, integral to the exhaust hood(s) being
protected, shall be shut down upon system actuation.
Along with the fire suppression system, the total system design
must include hand portable fire extinguisher(s) located within the
cooking/restaurant area that can be used to manually suppress a
fire that may be burning in an unprotected area.Class K extin-
guisher(s) must be provided for hazards where there is a potential
for fires involving combustible cooking media (vegetable or animal
oils and fats).Refer to NFPA 10, “Standard For Portable Fire
Extinguisher,”for additional information.
UL LISTING
The R-102 Restaurant Fire Suppression System has been tested
and is listed by Underwriters Laboratories, Inc.as a pre-engi-
neered system.The system is in compliance with ULTest
Standard 300.These tests require extinguishment of fires which
are initiated in deep fat fryers, ranges, griddles, char-broilers,
woks, upright broilers, chain-broilers, filters, plenum chambers,
hoods, and ducts after pre-loading each appliance with a pre-
scribed amount of cooking grease.Each fire is allowed to progress
to maximum intensity before the fire suppression system is
actuated.
SYSTEM APPROVALS
•UL EX3470
•ULC EX3470
•MEA 59-95E
DEFINITION OF TERMS
Actuation Gas Line:Piping and/or stainless steel braided hose
assemblies from the ANSUL AUTOMAN Regulated Release
Assembly which supplies high pressure nitrogen or carbon dioxide
to the Regulated Actuator Assembly for multiple-tank system actu-
ation.
Agent Tank:A pressure vessel containing the liquid agent.
ANSUL AUTOMAN Regulated Release Assembly (Electrical):
An assembly which contains the regulated release mechanism,
agent tank (ordered separately), expellant gas hose, solenoid, and
electric switch within a metal enclosure.The enclosure contains
knockouts to facilitate component hookups.
ANSUL AUTOMAN Regulated Release Assembly (Mechani-
cal):An assembly which contains the regulated release mecha-
nism, agent tank (ordered separately), and expellant gas hose
within a metal enclosure.The enclosure contains knockouts to
facilitate component hookups.
Authority Having Jurisdiction:The ‘‘authority having jurisdiction’’
is the organization, office, or individual responsible for ‘‘approving’’
equipment, an installation, or a procedure.The phrase ‘‘Authority
Having Jurisdiction’’is used in a broad manner since jurisdictions
and ‘‘approval’’agencies vary as do their responsibilities.Where
public safety is primary, the ‘‘authority having jurisdiction’’may be
a federal, state, local, or other regional department or individual
such as a fire chief, fire marshal, chief of a fire prevention bureau,
labor department, health department, building official, electrical
inspector, or others having statutory authority.For insurance pur-
poses, an insurance company representative may be the ‘‘author-
ity having jurisdiction.’’In many circumstances the property owner
or his designated agent assumes the role of the ‘‘authority having
jurisdiction;’’at government installations, the commanding officer
or departmental official may be the ‘‘authority having jurisdiction.’’
Blow-Off Cap:A siliconized rubber or metal cap which covers the
end of the nozzle to protect the nozzle tip and minimize cooking
grease migration into the nozzle orifice.
Branch Line:The agent distribution piping which extends from the
supply line to the nozzle(s).
Bursting Disc:A disc installed in the tank adaptor which mini-
mizes the remote chance of siphoning of the agent into the dis-
charge piping during extreme temperature variations.
Cartridge:A hermetically sealed, steel pressure vessel containing
nitrogen or carbon dioxide gas used to pressurize the agent tank.
Cooking Appliance:Includes fryers, griddles, ranges, upright
broilers, chain broilers, natural charcoal broilers, or char-broilers
(electric, lava rock, gas-radiant, or mesquite).
Cooking Area:Cooking area is defined as the maximum surface
that requires protection.Each type of appliance has a defined
cooking area with parameters that vary for each appliance.For
example, the cooking area for a griddle is the entire flat cooking
surface, while a fryer may have two areas that need consideration,
depending on whether the fryer has a dripboard or not.
Conduit Offset Assembly:A pre-formed piece of conduit which
can be installed between the ANSUL regulated release and the
conduit to allow the wire rope for the detection, gas valve and
remote manual pull station to be installed in a more convenient
manner.

(Part No.429853) contains the regulated release mechanism,
expellant gas hose for agent tank hookup, and enclosure knock-
outs to facilitate installing actuation piping;expellant piping;detec-
tion system;and additional equipment.This regulated release
assembly is used in single, double, and multiple-tank systems and
must be mounted to a rigid surface.The release mechanism can
be used to interconnect both the actuation and expellant gas lines
as required per system design.The regulator is designed to allow
a constant flow of gas into the tank at 110 psi (7.6 bar) when the
system is actuated.The agent tank must be ordered separately.
In single, double, and multiple-tank systems, the provided expel-
lant gas hose connects the agent tank to the bottom outlet of the
regulator.In double and multiple-tank system configurations, the
back outlet of the regulator is used as an expellant gas feed for
one additional tank-enclosure or tank-bracket hookup.The enclo-
sure contains the required knockouts to facilitate this connection.
If a pressure switch is to be attached to the regulator, additional fit-
tings are required.
The tank is mounted within the enclosure.The tank contains an
adaptor/tube assembly with a burst disc union.The burst disc
helps prevent siphoning of the agent up the pipe due to significant
temperature fluctuations in the area where the tank is located.The
tank is stainless steel and, under normal conditions, requires
hydrostatic testing every twelve years.
The detection and additional equipment required per system
design are connected to the release mechanism.The enclosure
contains knockouts to facilitate detection and additional hookups.
The system can be actuated automatically or manually.Automatic
actuation occurs when a fusible link within the detection system
separates in a fire condition.Manual actuation of the system
occurs when personnel pull on the remote manual pull station
pull ring.

DETECTORS
The detector consists of three basic components:the bracket, link-
age, and fusible link.(Fusible links are not included and must be
ordered separately.) The bracket holds the entire assembly to the
mounting surface.The linkage is used to support the fusible link.
The fusible link is designed to separate at a specific temperature
and release the wire rope, thereby actuating the regulated release
mechanism.
The scissor style detector allows the wire rope to be strung com-
pletely through the detection system conduit and brackets first and
the detector linkage assemblies are then clipped on later.
The detector consists of two types of assemblies:
The Terminal Detector (Part No.435546) includes a test link and
is placed last in a series of detectors.This detector is sometimes
referred to as the end-of-line detector and is thus named because
it is at the point at which the wire rope “terminates,”or is anchored
at the detector bracket.Only one terminal detector is required per
detection system.
The Series Detector (Part No.435547) is any detector located in-
line between the regulated release assembly and the terminal
detector.
When using Part No.435546 and 435547 detectors, a total of 15
detectors can be in one detection system:14 series detectors, Part
No.435547 and 1 terminal detector, Part No.435546.
Note:Series Detector, Part No.435547, is also available as Part
No.435548, 25/Pkg.

PULLEY ELBOWS
There are two types of pulley elbows used to change the direction
of the wire rope by 90°.ANSUL recommends for temperatures not
in excess of 700 °F (371 °C).Part No.415670 has socket ends
with set screws for 1/2 in.conduit, and Part No.423250 has com-
pression ring ends also for 1/2 in.conduit.Pulley elbows must be
ordered in quantities of 50 as Shipping Assembly Part No.415671
(socket end type) and Part No.423251 (compression end type).

PULLEY TEE
The Pulley Tee (Part No.427929) is used to change the direction
of two wire ropes by 90°.It must be used in areas where the tem-
peratures are within the range of 32 °F to 130 °F (0 °C to 54 °C).
Pulley tees can be used in mechanical gas valve actuation lines
and remote manual pull station lines.Pulley tees cannot be used
within a detection line.

STAINLESS STEEL CABLE
The 1/16 in.stainless steel cable is run from the terminal detector,
through conduit, all series detectors and pulley elbows, and into
the regulated release mechanism trip lever.When any fusible link
separates, the tension on the cable is relaxed, and the trip lever
actuates the regulated release mechanism.The cable can also be
used for mechanical gas valves and remote manual pull stations.
The cable is available in 50 ft (15 m) (Part No.15821) and 500 ft
(152.4 m) (Part No.79653) lengths.

ELECTRICAL GAS VALVES
The electrical gas valves are designed to shut off the flow of either
natural or LP gas to the appliances upon actuation of the regulat-
ed release assembly.The valves are available in sizes of 3/4 in.,
1 in., 1 1/4 in., 1 1/2 in., 2 in., 2 1/2 in., and 3 in.The valve is held
open by an energized solenoid and upon system actuation, the
switch contacts in the regulated release assembly open, thus de-
energizing the circuit to the gas valve solenoid, causing the valve
to close.Valves are available in 120 VAC and are UL Listed.

In addition to eliminating the siphoning effect, the common in-line
burst disc assembly eliminates the possibility of one or more indi-
vidual discs located in the tank adaptor from failing to burst.The
assembly consists of a stainless steel body which houses the
burst disc.When utilizing this assembly in a manifolded system, it
is necessary to modify (remove) the burst disc located in all of the
R-102 tank adaptors in the system.The in-line burst disc assem-
bly is to be mounted as close to the tank outlet as possible.After
system discharge, the assembly must be disassembled and a new

SYSTEM DESIGN
The ANSUL R-102 Restaurant Fire Suppression System may be
used on a number of different types of restaurant cooking appli-
ances and hood and duct configurations.The design information
listed in this section deals with the limitations and parameters of
this pre-engineered system.Those individuals responsible for the
design of the R-102 system must be trained and hold a current
ANSUL certificate in an R-102 training program.
The R-102 and the PIRANHA systems use compatible agents and
components, therefore, they may be used together for cooking
appliance, hood, and duct protection.The primary ANSUL
AUTOMANRelease can be either an R-102 or a PIRANHA
ANSUL AUTOMANRelease and can actuate up to two additional
R-102 or PIRANHARegulated Actuators.In systems utilizing a
101 remote release, any combination of the maximum number of
regulated actuators can be used.
•Both systems must actuate simultaneously.
•Each system must be designed and installed per its appropri-
ate manual.
•Adjacent appliances requiring protection must be protected
with the same type of system, either R-102 or PIRANHA,
unless the center-to-center spacing between the adjacent
R-102 and PIRANHA nozzles is no less than 36 in.(91.4 cm).
•When appliances are protected with R-102 nozzles, the hood
and connecting duct above those appliances cannot be pro-
tected with PIRANHA nozzles.
•Mixing systems in a common plenum is not allowed.
One of the key elements for restaurant fire protection is a correct
system design.This section is divided into ten sub-sections:Noz-
zle Placement Requirements, Tank Quantity Requirements, Actu-
ation and Expellant Gas Line Requirements, Distribution Piping
Requirements, Detection System Requirements, Manual Pull Sta-
tion Requirements, Mechanical Gas Valve Requirements, Electri-
cal Gas Valve Requirements, Electrical Switch Requirements, and
Pressure Switch Requirements.Each of these sections must be
completed before attempting any installation.System design
sketches should be made of all aspects of design for reference
during installation.
NOZZLE PLACEMENT REQUIREMENTS
This section gives guidelines for nozzle type, positioning, and
quantity for duct, plenum, and individual appliance protection.This
section must be completed before determining tank quantity and
piping requirements.
Duct Protection – Single Nozzle
All duct protection is UL listed without limitation of maximum duct
length (unlimited length).This includes all varieties of ductworks
both horizontal and vertical including ducts that run at angles to
the horizontal and ducts with directional bends.
The R-102 system uses different duct nozzles depending on the
size of duct being protected.
GENERAL INFORMATION
1.Nozzles must be located 2-8 in.(5-20 cm) into the center of the
duct opening, discharging up.See Figure 1.
FIGURE 1
000173
2.In installations where a UL listed damper assembly is
employed, the duct nozzle can be installed beyond the 8 in.
(20cm) maximum, to a point just beyond the damper assem-
bly that will not interfere with the damper.Exceeding the maxi-
mum of 8 in.(20 cm) in this way will not void the UL listing of
the system.
3.Previously listed 3 flow number and 5 flow number duct pro-
tection detailed in earlier published manual, Part No.418087-

Example:Protection is required for a duct that has an "A" dimen-
sion of 8.0 in.(20 cm) wide and a "B" dimension of 55 in.(140 cm)
long.
Referring to the table in Figure 2, if the "A" dimension is 8.0 in.(20
cm), the "B" dimension must not exceed 58.5 in.(149 cm).In this
example, the "B" dimension is 55 in.(140 cm), therefore, this duct
can be protected with a three flow application.
Read over from the 8.0 in.(20 cm) line on the table to the 1W
Module column.At that point, the chart shows that the "B" module
length for the 1W nozzle can be 22.0 in.(56 cm).Center the 1W
nozzle in that module.The 2W module can now be centered with-
in the remaining module.

Duct Protection – Multiple Nozzle (Continued)
•Ducts over 100 in.(254 cm) perimeter may be modularized using
2W nozzles (Part No.419337)
•No round duct option available
•Follow the design chart to determine maximum module size for
each 2W nozzle
•When determining number of nozzles required, it is sometimes
an advantage to check the chart using the shortest side as Side
"A" and then recheck it using the longest side as Side "A".This
comparison may reveal a need for a lesser quantity of nozzles
one way versus the other way.
When working with Chart 1, the quantity of nozzles determined
must be equally divided within the duct area.
When working with Chart 2, one half of the quantity of nozzles
determined must be equally positioned in the top half of the area
of the duct and the remaining half of the nozzles must be posi-
tioned in the bottom half of the duct area.
Example:The duct to be protected has a Side "A" of 40 in.
(101.6cm) and a Side "B" of 60 in.(152.4 cm).Referring to the
design chart, this duct requires 4 nozzles.One half of 4 = 2.
Therefore, 2 nozzles must be equally positioned in each of the two
duct areas.See Figure 3.

Transition Protection
Transitions are protected at a point in the transition where the
perimeter or the diameter is equal to or less than the maximum
size duct that can be protected.The nozzle(s) must be located in
the center of the area at that point, or center of the module pro-
tected when more than one duct nozzle is required.Note:Nozzles
to protect ducts with a transition that is more than 4ft (1.2 m)
in height,will be required to be positioned in the opening of
the transition from the hood 2 to 8 in.(5.1 to 20.3cm) into the
opening using standard duct nozzle design parameters.See
Figure 4.
FIGURE 4
000174
Electrostatic Precipitator Protection
Some restaurant ventilating ducts have an electrostatic precipita-
tor installed at or near the base.These precipitators are generally
small and are used to aid in the cleaning of exhaust air.
Ducts with precipitators located at or near the base can be pro-
tected using duct nozzle(s) above the precipitator and 1/2N noz-
zle(s) (Part No.419334) for the precipitator.One 1/2N nozzle must
be used for each cell being protected.This nozzle tip is stamped
with 1/2N, indicating that it is a 1/2-flow nozzle and must be count-
ed as 1/2 flow number.
When protecting ducts equipped with precipitators, the duct noz-
zle(s) must be installed above the precipitator and aimed to dis-
charge downstream.If the area above the precipitator is a duct, the
nozzle(s) must be positioned according to duct protection guide-
lines.If the area above the precipitator is a transition, the transition
guidelines must be followed.
The 1/2N nozzle (Part No.419334) must be centered 10 to 26 in.
(25 to 66 cm) below the precipitator and aimed to discharge at the
center of each precipitator cell.However, if it is physically impossi-
ble to mount the nozzle at 10 to 26 in.(25 to 66 cm) due to pre-
cipitator placement, the nozzle may be mounted closer than 10 in.
(25 cm).See Figure 5.
*IF PHYSICALLY IMPOSSIBLE AT 10 TO 26 IN.(25 TO 66 cm), NOZZLE MAY BE
MOUNTED CLOSER THAN 10 IN.(25cm).

The R-102 system uses the 1W Nozzle (Part No.419336) or the
1N Nozzle (Part No.419335) for plenum protection.The 1W noz-
zle tip is stamped with 1W and the 1N nozzle tip is stamped with
1N, indicating they are one-flow nozzles and must be counted as
one flow number each.When protecting a plenum chamber, the
entire chamber must be protected regardless of filter length.

between the filter height dimension, and aimed down the length.
The nozzle must be positioned 0-6 in.(0-15 cm) from the end of the
hood to the tip of the nozzle.See Figure 11.
FIGURE 11
For a plenum, either single or “V”bank, with a linear extension
longer than 10 ft (3.1 m), each bank may be protected using one
1N nozzle every 10 ft (3.1 m) or less depending on the overall
length of the plenum.See Figure 12.The nozzles may point in the
opposite directions as long as the entire plenum area is protected,
and the 10 ft (3.1 m) limitation is not exceeded.See Figure 13.The
nozzle positioning shown in Figure 14 is not an acceptable method
of protection because the plenum area directly under the tee is not
within the discharge pattern of either nozzle.

Appliance Protection
The following pages detail types of appliance protection.Each
design requires several factors:correct nozzle choice, correct noz-
zle height above hazard, correct nozzle location and correct aim-
ing point.
Fryer – Single Nozzle Protection
1.Design requirements for fryers are broken down into two
types.
A.FRYERS WITHOUT DRIPBOARDS
If the fryer does not include a dripboard, measure the
internal depth (horizontal dimension from front to back)
and length of the frypot.
B.FRYERS WITH DRIPBOARDS
If the fryer includes any dripboard areas, measure both
the internal depth (horizontal dimension from front to
back) and length of the frypot portion, and then measure
the internal depth and length of the overall hazard area
including any dripboard areas.
2.Using Table, “Maximum Cooking Area Dimension – Single
Nozzle Fryer Protection,”determine which nozzle is needed
to protect the fryer based on the maximum dimensions listed.
A.If the fryer does not include a dripboard, use the maxi-
mum dimensions listed in the first column of the table to
select the correct nozzle.
B.If the fryer includes any dripboard areas, use both the
maximum frypot dimensions in the first column of the
table, and the maximum overall dimensions in the second
column of the table to select the correct nozzle.None of
the maximum dimensions in either column may be
exceeded.
3.If either the maximum frypot or the overall sizes are exceed-
ed, an additional nozzle(s) will be required.Refer to the mul-
tiple nozzle requirements.
Example:A fryer with a dripboard.The inside of the frypot without
the dripboard measures 18 in.in depth x 18 in.in length (46 cm x
46 cm) and the inside of the overall area including the dripboard
measures 18 in.in depth x 24 in.in length (46 cm x 61 cm).From
the Table “Maximum Cooking Area Dimension – Single Nozzle
Fryer Protection,”either the 3N or the 290 nozzle should be select-
ed to protect the fryer, depending on the maximum nozzle height
above the fryer and the positioning requirements allowed.Refer to
appropriate Figures.

Fryer – Multiple Nozzle Protection
Design Requirements:
Fryers exceeding the coverage of a single nozzle can be divided
into modules.Each module must not exceed the maximum area
allowed for a single nozzle.However, when utilizing multiple nozzle
protection, the longest side allowed for a fryer with dripboard can
be used, regardless of whether the fryer has a dripboard or not.
The maximum size fryer that can be modularized is 864 in.2
(5574cm2) or in terms of ft, 6 ft2 (0.6 m2).
1.Design requirements for multiple nozzle fryers are broken
down into two types:
A.FRYERS WITHOUT DRIPBOARD(S)
If the fryer does not include a dripboard, measure the inter-
nal depth (horizontal dimension from front to back) and
length of the frypot.Then, multiply the depth and length to
obtain the area of the frypot in square inches.
B.FRYERS WITH DRIPBOARD(S)
If the fryer includes any dripboard areas, measure both the
internal depth and length of the frypot portion, and then
measure the internal depth and length of the overall hazard
area including any dripboard areas.
Determine the area of both the frypot and the area of the
overall vat by multiplying corresponding depth and length
dimensions.
2.Divide the frypot or overall vat into modules, each of which can
be protected by a single nozzle, based on the maximum
dimension and area coverage of the nozzle as specified in
Table, “Maximum Cooking Area Dimension – Multiple Nozzle
Protection.”
A.If the module considered does not include any portion of
the dripboard, use only the maximum frypot area and max-
imum dimension listed in the first column of the table to
select the correct nozzle.
B.If the module considered includes any dripboard areas, use
both the maximum frypot area and dimension listed in the
first column of the table, and the maximum overall area and
dimensions listed in the second column of the table to
select the correct nozzle.
3.None of the maximum dimensions in either column may be
exceeded.If either the maximum frypot or the overall sizes are
exceeded, the area divided into modules will need to be rede-
fined with the possibility of an additional nozzle.
Options For Modularizing Fryers
The following Figure 20 shows approved methods of dividing (mod-
ularizing) fryers so that each section can be properly protected.
Example:A fryer with a dripboard.The inside vat without the drip-
board measures 18 in.in depth x 30 in.in length (46 cm.x 76 cm)
and the inside of the overall vat including the dripboard measures
24 in.in depth x 30 in.in length (61 cm x 76 cm).Because the fryer
is 30 in.(76 cm) in length, it exceeds the coverage of a single
nozzle.
Dividing the length in half, each module now has an overall vat
dimension of 24 in.in depth x 15 in.in length (61 x 38 cm).From
the Table, “Maximum Cooking Area Dimension – Multiple Nozzle
Fryer Protection,”either the 3N or the 290 nozzle should be select-
ed to protect each fryer module, depending on the maximum noz-
zle height above the fryer and the positioning requirements
allowed.Refer to appropriate Figures, 15 through 19.
See additional examples in Appendix Section.

Multiple Nozzle Fryer Protection – Tilt Skillet / Braising Pan
Protection for tilt skillets or braising pans is to be based upon the
coverage limitations provided for deep fat fryer protection.Refer to
Section IV, DESIGN, starting on Page 4-10, for maximum fryer
nozzle coverages and maximum fryer nozzle height limitations.
Although the maximum 6 ft2 (0.6 m2) total surface cooking area
requirement applies to fryer protection, it does not apply to tilt skil-
lets or braising pans.
Each tilt skillet/braising pan protected module must not exceed the
fryer limitations for “MAXIMUM SIZE MODULE OVERALL WITH
DRIPBOARD”coverage per nozzle as described in Table on Page
4-11.
Tilt skillets and braising pans generally utilize a hinged cover.Fryer
protection nozzles are to be placed toward the front of the appli-
ance to minimize the potential for the tilt skillet or braising pan
cover to interfere with the nozzle discharge.See Figures 25 and
26.

Griddle Protection 1W (1-Flow) Nozzle – Low Proximity
Application
15 in.to 20 in.(38.1 cm to 50.8 cm) above the cooking surface.
The low proximity 1-flow nozzle application for the protection of
griddles requires the 1W nozzle, Part No.419336.
The nozzle tip is stamped with 1W indicating that this is a one-flow
nozzle and must be counted as one flow number.
When using the 1W nozzle for low proximity griddle protection with
our without obstruction, the maximum length of the cooking sur-
face to be protected must not exceed 26 in.(66.0 cm).The nozzle
must be centered at one end of the maximum 26 in.(66.0 cm)
length, aimed along a centerline to a point 20 in.(50.8 cm) from
the end of the length, protecting a maximum width of 20.5 in.
(52.1cm).
The 1W nozzle tip must be positioned at or below the obstruction,
if present.The protected area begins at the point straight down
from the nozzle tip.The nozzle can be positioned above the edge
of the hazard area to be protected.See Figures 51 and 52.
Note:If the hazard area exceeds the single nozzle coverage list-
ed above, additional nozzles will be required.The additional noz-
zle can be positioned in front at high proximity or at the side at low
proximity.

Chain Broiler Protection
The following listed protection guidelines can be applied to any
manufacturer’s chain broilers, if the chain broiler meets the speci-
fied parameters.Chain broilers utilizing catalytic converters can
be protected from overhead using model specific protection iden-
tified in the “Specific Application by Model”section in System
Design.Or, they can be protected with standard 1N nozzle hori-
zontal chain broiler protection with the nozzles positioned at either
end of the chain broiler openings.Refer to the Horizontal Chain
Broiler Protection section for specific design information.
Horizontal Chain Broiler Protection
The R-102 system can use two 1N Nozzles (Part No.419335) for
horizontal chain broiler protection.The nozzle tip is stamped 1N,
indicating that this is a one-flow nozzle and must be counted as
one flow number (total of two flow numbers for each chain broiler
being protected).
Two 1N nozzles are always needed for chain broiler protection
when the hazard area to be protected does not meet the
“Overhead Broiler Protection”requirements.The maximum inter-
nal size of the broiler is 43 x 31 in.(109 cm x 79 cm).The nozzles
must be positioned at each end of the enclosed cooking chamber
1 to 3 in.(2.5 to 7.5 cm) above the surface of the chain and a max-
imum distance of 4 in.(10 cm) away from the broiler opening.The
nozzles may be mounted at either corner as long as they are at
opposite ends of the chain broiler and positioned to discharge
diagonally across the top of the chain.See Figures 53 and 54.

FIGURE 53
FIGURE 54
000247
Overhead Chain Broiler Protection
The R-102 system can use two 1W Nozzles (Part No.419336) for
overhead chain broiler protection.The nozzle tip is stamped with
1W, indicating that this is a one-flow nozzle and must be counted
as one flow number.
Overhead protection is only available for chain broilers with
exhaust opening dimensions that are not less than 60% of the
internal broiler length and not less than 60% of the internal broiler
width, to a minimum size of 12 in.x 12 in.(30.5 x 30.5 cm).Internal
broiler size can not be larger than 32 in.x 34 in.(81 x 86 cm).
When overhead protection is used, the nozzles must be centered
above the exhaust opening within 4 to 8 in.(10 to 20 cm) of each
other and they must be located 10 to 26 in.(25 to 66 cm) above
the top of the broiler surface.See Figure 55.
FIGURE 55
000248
The nozzles may vary in position as long as they are evenly
spaced from the exhaust center and are always 180°opposite of
each other.If the opening is not square, the nozzles must be posi-
tioned along the centerline, parallel to the longest side of the open-
ing.See Figure 56.

Overhead Chain Broiler Protection(Continued)
Example No.1 – Internal broiler size is 24 in.long x 20 in.wide
(61 x 51 cm), with an opening of 16 in.x 16 in.
(40.6 x 40.6 cm).
To determine minimum opening size, multiply the
internal length and the internal width by 0.6:
Length of opening – 24 in.x 0.6 = 14.4 in.
(61 cm x 0.6 = 36.6 cm)
Width of opening – 20 in.x 0.6 = 12.0 in.
(51 cm x 0.6 = 30.5 cm)
The minimum allowable opening for overhead protec-
tion would be 14.4 in.x 12.0 in.(36.6 x 30.5 cm).
This example would be acceptable for overhead pro-
tection.
Example No.2 – Internal broiler size is 30 in.long x 24 in.wide
(76 x 61 cm) with an opening of 22 in.x 12 in.
(56 x 30 cm).
To determine minimum opening size, multiply internal
length and internal width by 0.6:
Length of opening – 30 in.x 0.6 = 18.0 in.
(76 cm x 0.6 = 45.7 cm)
Width of opening – 24 in.x 0.6 = 14.4 in.
(61 cm x 0.6 = 36.6 cm)
Minimum allowable opening for overhead protection
would be 18 in.x 14.4 in.(45.7 x 36.6 cm).
Because this broiler has an opening of 22 in.x 12 in.,
the 12 in.width is below the minimum allowable cal-
culated dimension of 14.4 in.(36.6 cm) and therefore
would not be acceptable for overhead protection.
Salamander Broiler Protection
The R-102 system uses three different nozzle locations for sala-
mander broiler protection.All of the design options require a one-
flow nozzle.
Salamander Broiler Protection – 1N (1-Flow) Nozzle Overhead
A salamander broiler with a maximum hazard area (internal broil-
er chamber) of 16 in.(41 cm) deep x 29 in.(74 cm) wide can be
protected using a 1N nozzle, Part No.419335.The nozzle tip is
stamped with 1N, indicating that this is a one-flow nozzle.
The single 1N nozzle must be located directly in line with either
vertical edge of the broiler opening, 6 in.(15 cm) to 12 in.(30 cm)
in front of the broiler, and 0 in.to 12 in.(30 cm) above the top of
the broiler.The nozzle must be aimed at the center of the broiler
opening.See Figure 57a.
FIGURE57a

Salamander Broiler Protection – 1F (1-Flow) Nozzle Overhead
A salamander broiler with a maximum hazard area (internal broil-
er chamber) of 15 in.(38 cm) deep x 31 in.(79 cm) wide can be
protected using a 1F nozzle, Part No.419333.The nozzle tip is
stamped with 1F, indicating that this is a one-flow nozzle.
The single 1F nozzle must be located directly in line with the cen-
ter of the broiler opening, 8 in.(20 cm) to 12 in.(30 cm) in front of
the broiler and 12 in.(30 cm) to 18 in.(46 cm) above the top of the
broiler.The nozzle must be aimed at the center of the top broiler
opening when the grate is located in the middle position.The noz-
zle must be orientated so the nozzle tip flats are parallel with the
grate left to right centerline.See Figure 57b.

Nieco Broiler Model 940,962 or 960 With Catalytic Converter
Protection
Note:Nieco broilers without catalytic converters use standard
chain broiler protection options.
Certain models of the Nieco broiler (Models 940, 962, and 960)
are equipped with a catalytic converter to comply with new clean
air laws.Because of the converter, it is necessary to protect these
broilers in a special way.The guidelines for protecting these broil-
ers are as follows:
–The maximum internal broiling area is 29 in.x 23.5 in.(74 cm
x 60 cm).
–An R-102 3-gallon system with a maximum of 6 flow numbers,
must be used for protection of each broiler, including plenum
and duct.
–Each individual broiler must be protected with a minimum of (2)
two, 1N nozzles, Part No.419335.The nozzles must be locat-
ed as shown in Figure 80.
–The broiler must be fitted with two 1 in.(2.5 cm) high agent bar-
riers on the angled surface of the broiler.If these have not been
completed by the equipment supplier, they must be added in
the field.

OVERLAPPINGNOZZLECOVERAGE
Overlapping Coverage – Option 1
For each group of protected appliances under a common hood(s),
the overlapping nozzles must be located from right to left so that
each end nozzle is located a maximum of 6 in.(15.2 cm) inside the
outside edge of the cooking hazard of each end appliance, and the
inside overlapping nozzles must be located between the two end
nozzles at a maximum spacing of 12 in.(30.5 cm).
Hazard Zone
The hazard zone is defined as a theoretical, flat and level, rectan-
gular surface, that includes all of the cooking hazards of the pro-
tected appliances under a common hood(s).The purpose of the
hazard zone is to provide a means of locating the appliances and
the overlapping nozzles, as well as aiming the overlapping noz-
zles.The hazard zone measures 28 in.(71.1 cm) deep by the
length of the cooking hazard(s).The centerline of the hazard zone
must bisect the 28 in.(71.1 cm) depth (from front to back) and run
from right-to-left for the full width of the hazard zone.
Overlapping Nozzle Appliance Protection
Overlapping Nozzle Appliance Protection is defined as protection
of cooking appliances by nozzles spaced uniformly at uniform ele-
vations under a common hood(s).Overlapping protection of appli-
ances is continuous for the full length of the hood or divided when
group(s) of protected appliances are separated by counters or
appliances not requiring protection.
Full hood continuous protection is defined as overlapping noz-
zle appliance protection that covers the appliance line-up located
under the total hood length.All appliances requiring protection are
the appliances under the hood that can be an ignition source of
grease in the hood, grease removal device or the duct.
Group protection is defined as overlapping nozzle appliance pro-
tection that protects individual hazard zones located under a com-
mon hood.These “groups”of appliances may be separated by
appliances not requiring protection, such as steam equipment or
work tables, or by dedicated appliance protection, such as sala-
mander broilers.
See Figure 91d (full hood continuous protection) and Figure 91e
(multiple group protection).
Dedicated Nozzle Appliance Protection
Appliance protection using dedicated nozzle coverage is defined
as protection of cooking appliances with enclosed cooking haz-
ards, such as upright broilers, which cannot be protected with
overlapping nozzles and therefore must be protected with nozzles
dedicated to the appliance.
General Design Limitations
•Maximum depth of zone is 28 in.(71.1 cm).
•The 245 nozzle, Part No.419340, is the only approved nozzle for
overlapping (zone) protection.
•Nozzle must be located 0 in.to 6 in.(0 cm to 15.2 cm) forward
of zone centerline, aimed back at the zone centerline.
•Nozzles must be spaced a maximum of 6 in.(15.2 cm) from
each end of hazard and then a maximum of 12 in.(30.5 cm) on
center for the remaining overlapping nozzles until the complete
hazard is covered.
•For appliance hazard surfaces with listed protection exceed-
ing the standard hazard zone of 28 in.(71.1 cm) in depth, the
hazard surface(s) must be aligned with the back edge of the
hazard zone, with the front edge overhanging the front edge of
the zone.See Appliance Chart, Table 1.
•For appliance hazard surfaces that exceed the listed protec-
tion sizes, multiple zones must be utilized.Align entire hazard
surface area within the multiple zones.
•All hood, duct, individual appliance, and piping limitations are as
specified in the R-102 Design, Installation, Recharge and
Maintenance Manual, Part No.418087.
•All appliance protection currently listed in the R-102 Design
Manual, Part No.418087, is also approved protection.Zone pro-
tection can be considered optional protection.

Overlapping Appliance Nozzle and Hazard Zone Locations
1.All overlapping appliance nozzles must be the “245”nozzle,
Part No.419340, and must be located under a common hood
at the same height above the hazard zone, in a straight line
from right to left and aimed at the centerline of the hazard
zone.The overlapping nozzle is used for both continuous over-
lapping and multiple group overlapping protection.
2.The hazard zone must be positioned (located) so that all appli-
ance hazard surfaces are within the zone.For appliance haz-
ard surfaces with listed protection exceeding the standard
hazard zone size of 28 in.(71 cm) in depth (see Table 1), the
hazard surface(s) must be aligned with the back edge of the
hazard zone, with the front edge overhanging the front of the
zone.
3.The overlapping appliance nozzles must be located 40 in.to
45 in.(1 m to 1.1 m) above the top surface of the protected
appliances.See Figure 91c.
Exception No.1:Nozzle dimensions for wok protection are
measured to bottom of wok.Exception No.2:When using
overlapping appliance nozzles in areas where there is a back
shelf, the nozzle cannot be positioned in the shaded area as
shown in Figure 91b.
Also, back shelf must not extend more than 11 in.(27.9 cm)
over the hazard zone and cannot be less than 20 in.(50.8cm)
above the hazard zone.See Figure 91b.

Detection Requirements For Overlapping Appliance
Protection
When utilizing overlapping appliance protection, fusible link detec-
tors must be installed on a maximum of 2 ft (0.61 m) centers,
starting with detectors located in (under) the duct opening(s).
Starting from the detector under the duct opening, add detectors
on 2 ft (0.61 m) maximum spacing until the complete length of the
plenum area is covered, from one end to the other.The location of
the last detector on each end of the plenum must not exceed
2 ft (0.61 m) from end of plenum.
Note:Standard detector coverage, as specified in “Design
Section,”is acceptable when utilizing dedicated nozzle cov-
erages.

Overlapping Coverage – Option 2
For each group of protected appliances under a common hood(s),
the overlapping nozzles must be located from right to left so that
each end nozzle is located a maximum of 11.5 in.(29.2 cm) inside
the outside edge of the cooking hazard of each end appliance, and
the inside overlapping nozzles must be located between the two
end nozzles at a maximum spacing of 25.5 in.(64.8 cm).
Hazard Zone
The hazard zone is defined as a theoretical, flat and level, rectan-
gular surface, that includes all of the cooking hazards of the pro-
tected appliances under a common hood(s).The purpose of the
hazard zone is to provide a means of locating the appliances and
the overlapping nozzles, as well as aiming the overlapping noz-
zles.The hazard zone measures 28 in.(711 mm) deep by the
length of the cooking hazard(s).The centerline of the hazard zone
must bisect the 28 in.(711 mm) depth (from front to back) and run
from right-to-left for the full width of the hazard zone.
Overlapping Nozzle Appliance Protection
Overlapping Nozzle Appliance Protection is defined as protection
of cooking appliances by nozzles spaced uniformly at uniform ele-
vations under a common hood(s).Overlapping protection of appli-
ances is continuous for the full length of the hood or divided when
group(s) of protected appliances are separated by counters or
appliances not requiring protection.
Full hood continuous protection is defined as overlapping noz-
zle appliance protection that covers the appliance line-up located
under the total hood length.All appliances requiring protection are
the appliances under the hood that can be an ignition source of
grease in the hood, grease removal device or the duct.
Group protection is defined as overlapping nozzle appliance pro-
tection that protects individual hazard zones located under a com-
mon hood.These “groups”of appliances may be separated by
appliances not requiring protection, such as steam equipment or
work tables, or by dedicated appliance protection, such as sala-
mander broilers.
See Figure 95 (full hood continuous protection) and Figure 96
(multiple group protection).
Dedicated Nozzle Appliance Protection
Appliance protection using dedicated nozzle coverage is defined
as protection of cooking appliances with enclosed cooking haz-
ards, such as upright broilers, which cannot be protected with
overlapping nozzles and therefore must be protected with nozzles
dedicated to the appliance.
General Design Limitations
•If overlapping appliance protection is mixed with dedicated appli-
ance protection on the same pipe system, THEOVERLAPPING
APPLIANCEPROTECTIONPIPINGREQUIREMENTSMUST
BEFOLLOWED.
•Overlapping protection requires the use of 3.0 gal (11.4 L)
tank(s) and a maximum of six (6) flows per tank.
•In installations using tanks only intended for overlapping protec-
tion, a single Double Tank nitrogen expellant gas cartridge can
be utilized with up to three (3) 3.0 gal (11.4 L) tanks.
•In installations using both overlapping protection and conven-
tional non-overlapping protection (ex.hood/duct or dedicated
appliance protection), a single Double Tank nitrogen expellant
gas cartridge can be utilized with up to three (3) 3.0 gal (11.4 L)
tanks, as long as none of the 3.0 gal (11.4 L) tanks exceed a
total flow output of more than six (6) flows.
•If more than six (6) flows will be used in a conventional non-
overlapping tank, it cannot share the same cartridge as tanks
intended for overlapping protection.In this case, an additional
Regulated Actuator Assembly with another expellant gas car-
tridge will be required.
•The 245 nozzle, Part No.419340, must be used for “end of zone”
protection.
•The 260 nozzle, Part No.419341, must be used for zone pro-
tection.
•Maximum depth of zone is 28 in.(71.1 cm).
•Refer to overlapping system piping requirements listed in Table 2.
•Nozzle must be located 0 in.to 12 in.(0 cm to 30.5 cm) forward
of zone centerline, aimed back at the zone centerline.
•Nozzles must be spaced a maximum of 11.5 in.(29.2 cm) from
each end of hazard and then a maximum of 25.5 in.(64.8 cm)
on center for the remaining overlapping nozzles until the com-
plete hazard is covered.
•For appliance hazard surfaces with listed protection exceed-
ing the standard hazard zone of 28 in.(71 cm) in depth, the haz-
ard surface(s) must be aligned with the back edge of the hazard
zone, with the front edge overhanging the front edge of the zone.
See Appliance Chart, Table 1.
•For appliance hazard surfaces that exceed the listed protec-
tion sizes, multiple zones must be utilized.Align entire hazard
surface area within the multiple zones.
•All hood, duct, and individual appliance protection are as speci-
fied in the R-102 Design, Installation, Recharge and Mainten-
ance Manual, Part No.418087.
•All appliance protection currently listed in the R-102 Design
Manual, Part No.418087, is also approved protection.Zone pro-
tection can be considered optional protection.

Overlapping Appliance Nozzle and Hazard Zone Locations
1.All overlapping appliance nozzles must be the 245 nozzle,
Part No.419340, for “end of zone”protection and the 260 noz-
zle, Part No.419341, for zone protection, and must be located
under a common hood at the same height above the hazard
zone, in a straight line from right to left and aimed at the cen-
terline of the hazard zone.The overlapping nozzle is used for
both continuous overlapping and multiple group overlapping
protection.
2.The hazard zone must be positioned (located) so that all appli-
ance hazard surfaces are within the zone.For appliance haz-
ard surfaces smaller than the standard hazard zone size, the
hazard surface can be located anywhere within the standard
hazard zone.For appliance hazard surfaces with listed pro-
tection exceeding the standard hazard zone size of 28 in.
(71cm) in depth (see Table 1), the hazard surface(s) must be
aligned with the back edge of the hazard zone, with the front
edge overhanging the front of the zone.
3.The overlapping appliance nozzles must be located 40 in.to
45 in.(1 m to 1.1 m) above the top surface of the protected
appliances.See Figure 94.
Exception No.1:Nozzle dimensions for wok protection are
measured to bottom of wok.Exception No.2:When using
overlapping appliance nozzles in areas where there is a back
shelf, the nozzle cannot be positioned in the shaded area as
shown in Figure 93.
Also, back shelf must not extend more than 11 in.(27.9 cm)
over the hazard zone and cannot be less than 18 in.(45.7cm)
above the hazard zone.See Figure 93.

ACTUATION AND EXPELLANT GAS LINE REQUIREMENTS
This section contains the guidelines for installing the actuation and
expellant gas lines between the regulated release mechanism reg-
ulator, each regulated actuator regulator, and each agent tank.
These limitations should be considered when selecting the com-
ponent mounting locations.
The actuation gas line is the length of pipe and/or hose that is run
from either the AUTOMAN Regulated Release Assembly or the
Remote Release Assembly that directs high pressure from the
cartridge in the release to actuate one or more additional
Regulated Actuator Assemblies.The actuation gas line can consist
of 1/4 in.Schedule 40 black iron, chrome-plated, stainless steel, or
galvanized steel pipe and fittings, and/or factory supplied stainless
steel braided actuation hose.
The expellant gas line is the length of pipe that is run from the
regulator in either the AUTOMAN Regulated Release Assembly or
a Regulated Actuator Assembly that directs regulated pressure to
the agent storage tanks to pressurize the tank and discharge the
agent.The expellant gas line shall consist of 1/4 in.Schedule 40
black iron, chrome-plated, stainless steel, or galvanized steel pipe
and fittings.
Actuation Gas Line – 6 to 8* Tanks Maximum
* 8 Tank maximum reflects the utilization of 3 tank regulated actuators.
1.Use only 1/4 in.Schedule 40 black iron, hot-dipped galva-
nized, chrome-plated, or stainless steel pipe and fittings.

Expellant Gas Line
1.The expellant gas line is installed from the regulated release
mechanism in double, three, and multiple-tank systems, and
from the regulated actuator assembly in multiple-tank sys-
tems.The expellant gas line is the piping and/or hose between
the regulator and the tank-enclosure/tank-bracket assembly.
The total length of the expellant gas line from the regulated
release mechanism or each regulated actuator assembly
must not exceed 30 ft (9 m) when using a “double-tank”car-
tridge, an LT-A-101-30 Cartridge, or a 101-30 Cartridge.See
Figures 103 and 104.

2.A combined total of nine fittings may be used in these lines,
eight 90°elbows and one tee.Two 45°elbows equal one 90°
elbow.
3.If two tanks are connected to the regulated release assembly
in a multiple-tank system arrangement, the total combined
length of the actuation and expellant gas lines must not
exceed 30 ft (9 m) when using a “double-tank”nitrogen car-
tridge, an LT-A-101-30 nitrogen cartridge, or a 101-30 carbon
dioxide cartridge.See Figure 101.
4.If three 3.0 gallon tanks are connected to the regulator in
either a regulated release or regulated actuator assembly,
only factory supplied expellant gas hose assemblies will be
utilized.Refer to Distribution Piping Requirements – 9.0
Gallon System, page 4-55 for additional design requirements.
DISTRIBUTION PIPING REQUIREMENTS
Once the nozzle placement and quantity of tanks has been deter-
mined, it is then necessary to determine the piping configurations
between the tank adaptor and each discharge nozzle.This section
contains the guidelines and limitations for designing the distribu-
tion piping so that the liquid agent will discharge from the nozzles
at a proper flow rate.These limitations should also be referred to
when selecting the mounting location for the regulated release
mechanism and agent tank.
General Piping Requirements
1.All R-102 system piping is straight line.Therefore, the need for
critical lengths and balancing is minimized.
2.Two 45°elbows count as one 90°elbow.
3.Each branch line includes the tee or elbow leading to it, and
all fittings within the branch line itself.
4.The minimum piping length of Schedule 40, 3/8 in.pipe from
the tank outlet to any nozzle protecting a range, fryer, or wok
must be 6 ft (1.8 m).
5.Pipe lengths are measured from center of fitting to center of
fitting.See Figure 105.
FIGURE 105
000778
6.All distribution piping must be 3/8 in.Schedule 40 black iron,
chrome-plated, or stainless steel.Do not use hot dipped gal-
vanized pipe on the distribution piping.
7.All threaded connections located in and above the protected
area must be sealed with pipe tape.Tape should be applied to
male threads only.Make certain tape does not extend over the
end of the thread, as this could cause possible blockage of the
agent distribution.
8.Before installing blow-off caps on nozzles, apply a small
amount of Dow Corning No.111 silicone grease across the
opening in the nozzle tip and also a small amount coating the
exterior of the blow-off cap.This will help keep cooking grease
from building up on the cap.
9.Tees used in the distribution piping can be used as thru tees,
side outlet tees, or bull tees.

DETECTION SYSTEM REQUIREMENTS
Once the fire suppression system design has been determined, a
detection system design must be completed.This section contains
guidelines and limitations for detection system installation.
Detector Identification
The two types of detectors are distinguished from each other by
their location in the detection system.
1.The Terminal Detector (Part No.417368) is the last in a series
of detectors, or the only detector used in a single-detector sys-
tem.This detector is thus named because it is at the point at
which the wire rope ends, or “terminates.”
2.A Series Detector (Part No.417369) is any detector located in-
line between the regulated release mechanism and the termi-
nal detector.
Detector/Pulley Elbow/Conduit Off-Set Design Limitations
1.Conduit runs, pulley elbows, and number of detectors per sys-
tem must be within the approved system guidelines.The fol-
lowing requirements must not be exceeded:
MaximumMaximumMaximum
Number ofNumber ofLength of 1/2
DetectorsElbowsin.Conduit

Scissors Style1520150 ft (45.7 m)
Detector
(Without
Off-Set Conduit
Scissors Style1516150 ft (45.7 m)
Detector (With
Off-Set Conduit
2.If the hazard requires more than 15 detectors, up to five 101
Remote Releases (Part No.433485) can be used for system
actuation.Each 101 remote release allows the use of a maxi-
mum of 15 “scissor”style detectors (14 series and 1 terminal)
for a total of 75 detectors if needed.
Detector Placement Requirements
EXHAUST DUCTS
Each exhaust duct must have at least one detector installed in the
duct entrance, located in the airstream of the cooking vapors, or at
a maximum of 20 ft (6.1 m) into the duct opening.See Figure 118.
FIGURE 118
000271
NOTICE
When gas appliances are used and the flue
gases from the burner are exhausted into the
duct, the detector must be kept out of the air
stream of these exhaust gases.These gases
can be very hot and could actuate the system
unnecessarily.
Duct openings that are long and narrow or large
enough to require multiple duct nozzles may
require additional detectors.
ELECTROSTATIC PRECIPITATOR
If an electrostatic precipitator is located at or near the base of the
exhaust duct, it is necessary to locate a detector below the pre-
cipitator, at the base of the duct, and also locate one in the duct,
just above the precipitator.See Figure 119.
When installing the detector bracket and system conduit, make
certain they do not interfere with the operation of the precipitator.
Note:On secondary filtration units utilizing multiple filter
stages/media, contact Ansul Technical Services for instructions.

Detector Replacement Requirements (Continued)
COOKING APPLIANCES
If the cooking appliance is located under an exhaust duct where a
detector has been mounted, it is normally not necessary to utilize
another detector for that cooking appliance, provided the detector
is not more than 12 in.(30 cm) into the duct and the appliance has
no larger cooking surface than 48 in.x 48 in.(121.9 cm x 129.1
cm).See Figure 120.
Note:If two (2) appliances are located under a duct opening
where a detector has been mounted and both appliances togeth-
er do not exceed a cooking surface of 48 in.x 48 in.(121.9 cm x
121.9 cm) and the detector is located above both the protected
appliances, it is not necessary to utilize an additional detector pro-
vided the duct detector is not more than 12 in.(30.5 cm) into the
duct opening.
FIGURE 120
000269
Each cooking appliance with a continuous cooking surface not
exceeding 48 in.x 48 in.(122 x 122 cm) can be protected by a min-
imum of one detector.Cooking appliances with a continuous cook-
ing surface exceeding 48 in.x 48 in.must be protected by at least
one detector per 48 in.x 48 in.cooking area.Detectors used for
cooking appliances must be located above the protected appli-
ance toward the exhaust duct side of the appliance.The detector
should be located in the air stream of the appliance to enhance
system response time.
Note:For overlapping detector coverage, see Page 4-45 for
design requirements.
Detection Line Requirements
CONDUIT
Rigid conduit or 1/2 inch EMT thin-wall conduit may be used.
Standard steel conduit fittings (compression type are recommend-
ed) must be employed to properly install the detection system.All
conduit or pipe must be firmly supported.When using pipe, make
certain that all ends are carefully reamed, deburred and blown
clear of chips and scale before assembly.
NOTICE
The conduit offset can be used at the top or bot-
tom of the regulated release to change direction
of the conduit.The conduit offset cannot be
used with pulley tees.All other changes in direc-
tion must be made by using ANSUL approved
pulley elbows, Part No.423254 or 415670.See
Figure 121.
FIGURE 121
000270
Fusible Link Selection
When possible, temperature readings should be taken at each
detector location to determine correct fusible link temperature rat-
ing.Temperature can be recorded using either a maximum regis-
tering thermometer, Part No.15240, temperature tape or any other
accurate thermometer.
FIGURE 122

MANUAL PULL STATION REQUIREMENTS
A remote manual pull station allows the R-102 system to be man-
ually operated at some point distant from the regulated release
assembly.The pull station should be installed at a height of 42-48
in.(107-122 cm), in accordance with the requirements of the
American Disabilities Act (ADA) and the Authority having Jurisdic-
tion.and located in the path of egress.The pull station is the only
source of manual actuation of the regulated release assembly.
The total length of the cable used for each manual pull station with-
in a system must not exceed 150 ft (46 m).
The maximum number of pulley elbows that may be used per pull
station is 20.
One pulley tee, Part No.427929, is allowed per cable system.
The maximum length of cable from the AUTOMAN to a pull station
is 150 ft (45.7 m) with a maximum of 20 pulley elbows used per
side of the tee.As the tee is located farther from the AUTOMAN,
the 150 ft (45.7 m) maximum must be observed but as pulley
elbows are placed between the AUTOMAN and the tee, they must
be deducted from the available pulley elbows (20) allowed on each
side.
Example:If 10 pulley elbows are placed between the AUTOMAN
and the pulley tee, the maximum available pulley elbows left for
use on each side of the tee is 10 per side.See Figure 123 for three
different examples.(Note:Both must be gas valves or both must
be pull stations.Mixing is not allowed.)

MECHANICAL GAS VALVE REQUIREMENTS
An ANSUL or ANSUL approved mechanical gas shut-off valve
system can be attached to the R-102 system.The system works
both mechanically and pneumatically by use of an air cylinder
located inside the regulated release assembly.Upon actuation of
the fire suppression system, a pneumatically-operated air cylinder
assembly will mechanically close the gas shut-off valve.
The total length of the cable for each mechanical gas valve must
not exceed 150 ft (46 m).The maximum number of pulley elbows
that may be used is 20 for each valve.
One pulley tee (Part No.427929) is allowed per cable system.
The maximum length of cable from the AUTOMAN to a gas valve is
150 ft (45.7 m) with a maximum of 20 pulley elbows used per side
of the tee.As the tee is located farther from the AUTOMAN, the
150ft (45.7 m) maximum must be observed but as pulley elbows are
placed between the AUTOMAN and the tee, they must be deducted
from the available pulley elbows (20) allowed on each side.
Example:If 10 pulley elbows are placed between the AUTOMAN
and the pulley tee, the maximum available pulley elbows left for
use on each side of the tee is 10 per side.See Figure 123 for three
different examples.

MECHANICAL GAS VALVE REQUIREMENTS (Continued)
All valves above are UL listed and approved.They may be mount-
ed in any position.Pipe threads are type NPT.Ambient operating
temperature range of all valves is 32 °F to 120 °F (0 °C to 49 °C).
The valves are not weatherproof and must be located indoors in
areas approved by the “authority having jurisdiction.”
ELECTRICAL GAS VALVE REQUIREMENTS
A UL Listed electrically-operated gas shut-off valve can be
attached to the R-102 system to provide an electrical means of
shutting off the gas line at a predetermined point.If an electric gas
shut-off valve is used in the system it must be attached with both
an electric (snap-action) switch and a manual reset relay.For more
information on the types of electric (snap-action) switches, refer to
the Electrical Switch, Field Installation section.The manual reset
relay is reviewed in this section.
All electrical connections should be performed by a QUALIFIED
ELECTRICIAN and in accordance with authority having
jurisdiction.
The following is a brief explanation of how the R-102 system oper-
ates with an Electric Gas Shut-off Valve attached:
With the regulated release cocked in the ready condition, the nor-
mally closed contacts in the snap-action switch allow current to
flow to the manual reset relay.With the relay coil energized, nor-
mally open contacts in the reset relay close, allowing the solenoid
in the gas valve to be energized.
Once the R-102 system is activated, the normally closed contacts
in the snap-action switch will open, de-energizing the reset relay.
This will, in turn, open the contacts in the relay which will cause the
gas valve to become de-energized and close.
The system must be re-armed and the “push to reset”button on
the reset relay must be operated to reopen the gas valve.
It is important to note that a power failure or an electrical power
interruption will cause the gas valve to close even though the sys-
tem was not fired.
In either case, whether in a fired condition or when a power failure
has occurred, the manual reset relay and electric gas shut-off
valve must be reset to resume a normal operating condition.For
resetting,refer to the “Recharge and Resetting Procedures”
section in this manual.
Approvals
ANSUL gas valves listed in this section are UL listed and approved
for 110 VAC.If more information is required, refer to the Gas and
Oil Equipment List of Underwriters Laboratories, Inc.under
“Electrically Operated Valves Guide No.440 A5”or consult Ansul
Incorporated, Marinette, Wisconsin 54143-2542.
If other gas valves are used, they shall be “UL listed electrically-
operated safety valves for natural or LP gas as required, of appro-
priate pressure and temperature rating, 110 VAC/60 Hz.”The infor-
mation on temperature and type of gas that the valves are suitable
for may be found in the Gas and Oil Equipment List of
Underwriters Laboratories, Inc.under “Electrically Operated
Valves Guide No.440 A5.”
The electrically operated gas valve must be of the type that needs
to be energized to remain open.

ALARM INITIATING SWITCH REQUIREMENTS
The Alarm Initiating Switch can be field mounted within the
ANSUL AUTOMAN release.The switch must be used to close a
supervised alarm circuit to the building main fire alarm panel when
the ANSUL AUTOMAN release actuates.This action will signal the
fire alarm panel that there was a system actuation in the kitchen
area.The switch kit contains all necessary mounting components
along with a mounting instruction sheet.See Page 5-19 for wiring
information.
The switch is rated 50 mA, 28VDC.

INSTALLATION INSTRUCTIONS
The installation information listed in this section deals with the limi-
tations and parameters of this pre-engineered system.Those indi-
viduals responsible for the installation of the R-102 system must
be trained and hold a current ANSUL certificate in an R-102 train-
ing program.
Before attempting any installation, the entire system design must
have been determined including:Nozzle Placement, Tank
Quantity, Actuation and Expellant Gas Piping, Distribution Piping,
and Detection System Requirements and an installation sketch
should be completed.
MOUNTING THE COMPONENTS
For successful system performance, the regulated release assem-
bly, regulated actuator assembly(ies), and tank-enclosure(s) or
tank-bracket assembly(ies) used must be located in areas where
the air temperature will not fall below 32 °F (0 °C) or exceed
130 °F (54 °C).The R-102 system is limited to interior applications
only.Also, the components must be arranged to conform to the
actuation and expellant gas line, and the distribution piping guide-
lines noted in “System Design.”
1.
Mount the regulated release assembly, OEM Release
Assembly, and each regulated actuator assembly required by
completing the following steps:See Figures 1, 2, and 3.
a.Select a rigid surface for mounting the enclosure.The
mounting locations must allow the regulated release
assembly and the regulated actuator assembly(ies) to be
within the limitation of the actuation and expellant gas line
lengths and must be able to support the weight of the
assembly(ies).When the OEMRelease Assembly is
mounted inside a cabinet, clearances shall be provided for
unrestricted movement of the release assembly compo-
nents within the closed cabinet.
b.Detach cover from the enclosure.Remove agent tank from
enclosure and the expellant gas line hose from the
tank/adaptor assembly.
c.Secure enclosure box to selected mounting location using
the four mounting holes.Use appropriate type of fasteners
depending on the mounting surface.
d.When mounting a 6-gallon manifolded system (or a 6-
gallon individual piped system) it is critical that each mount-
ing box is located as shown in Figure 3.There must be a
5/16 in.space between each box.Less than 5/16 in.will
cause interference with the covers, and more than a 5/16
in.will cause a gap between the two hose grommets which
will expose the hose to possible tampering or damage.
Remove the 7/8 in.knockout in the left side of the ANSUL
AUTOMAN release box and remove the 1 in.knockout in
the right side of the tank-enclosure box.Install grommets in
each (use ANSUL hose/grommet package, Part No.
418511).Remove 1/4 in.plug from back side of R-102
regular and install fixed end of secondary expellant gas
hose (included in hose/grommet package, Part No.
418511) in 1/4 in.regulator outlet and wrench tighten.
If not already done, mount both boxes to a rigid surface
using appropriate fasteners.
Fill tanks per instructions listed in Steps 3 and 4 on
Page 5-2-1.
Next, route hose through grommets and wrench tighten into
1/4 in.inlet of the adaptor on the tank in the tank/enclosure
assembly.Also install hose to tank adaptor in regulated
release and wrench tighten.See Figure 116 in “Design
Section”for details of hose routing.

INSTALLING THE ACTUATION AND EXPELLANT GAS LINE
Before installing any actuation or expellant gas line, the design
must be determined;and the regulated release assembly, each
regulated actuator assembly and each tank-bracket assembly
should be securely mounted.
General Piping Requirements
1.Use only 1/4 in.Schedule 40 black iron, hot-dipped galva-
nized, chrome-plated, or stainless steel pipe and fittings.
2.Before assembling the pipe and fittings, make certain all ends
are carefully reamed and blown clear of chips and scale.
Inside of pipe and fittings must be free of oil and dirt.
3.The piping and fitting connections must be sealed with pipe
tape.When applying pipe tape, start at the second male
thread and wrap the tape (two turns maximum) clockwise
around the threads, away from the pipe opening.
NOTICE
Do not allow tape to overlap the pipe
opening, as this could cause possible block-
age of the gas pressure.
Thread sealant or compound must not be
used.
4.When connecting actuation or expellant gas line piping, install
a 1/4 in.union near the tank inlet for easy disassembly later.
Note:Expellant gas line cannot use stainless steel braided hose.
Actuation Gas Line
Note:See Appendix for complete list and specifications when
using rubber hose for actuation gas line.
Install actuation gas line from the regulated release mechanism
high pressure side outlet (side opposite regulated outlet) through
the appropriate knockout in the enclosure by completing the
following steps:
1.Remove the 1/8 in.plug from high pressure side outlet.Install
the appropriate fitting for additional equipment attachment as
required.A 1/4 x 1/8 in.reducing fitting is required to connect
the 1/4 in.actuation line.See Figure 7.

INSTALLING THE DISTRIBUTION PIPING
Before the following procedures can be completed, the piping
design must already be determined;and the actuation and expel-
lant gas lines from the regulated release, each regulated actuator,
and each tank-enclosure or tank-bracket assembly should already
be installed.
These installation instructions are identical for single, double, and
multiple-tank systems except for the quantity of tanks and hazard
areas to be covered.
General Piping Requirements
1.Use Schedule 40 black iron, chrome-plated, or stainless steel
pipe and fittings.
NOTICE
Do not use hot-dipped galvanized iron pipe or
fittings in the agent distribution piping.
2.Before assembling the pipe and fittings, make certain all ends
are carefully reamed and blown clear of chips and scale.
Inside of pipe and fittings must be free of oil and dirt.
3.The distribution piping and fitting connections, located in or
above the hood or the protected area, must be sealed with
pipe tape.When applying pipe tape, start at the second male
thread and wrap the tape (two turns maximum) clockwise
around the threads, away from the pipe opening.
NOTICE
Do not allow tape to overlap the pipe opening as
the pipe and nozzles could become plugged.
Thread sealant or compound must not be used
as it could plug the nozzles.
4.Distribution piping may be run independently or two agent
tanks may be manifolded together and run to the predeter-
mined hazard area.Only agent tanks expelled from the same
cartridge may be manifolded.
NOTICE
Closely follow the piping requirements for each
size system, as detailed in the “System Design”
section, when installing distribution piping.
5.Branchline tees can be used to create more than one branch
and can be installed as a thru tee, side outlet tee or bull tee.
Pipe Hanger Recommended Guidelines
1.Space hangers as follows:
Maximum Recommended
Pipe SizeDistance Between Hangers______________________________
3/8 in.5 ft (1.5 m)
2.Hangers should be placed between elbows when the distance
is greater than 2 ft (0.6 m).
Piping Installation
1.Starting at the tank, pipe directly from the union located on the
tank adaptor.A reducing fitting may be necessary to conform
to the distribution piping.
2.Based on the piping sketch developed in the “System Design”
section of this manual, install the supply line and position the
tees at points where branch lines must be installed.See
Figure 14.
3.Run all branch lines to the hazard area and connect each
nozzle.(Make certain all piping is securely bracketed.)
FIGURE 14
000302
4.Make certain all threaded connections are properly tightened.
Threaded connections located in the protected area(s) and
above the hood must be sealed with Teflon pipe tape, as a
minimum.Apply pipe tape to male threads only.Make certain
tape does not extend over the end of the thread, as this could
cause possible blockage of the agent distribution.
Pipe tape minimizes friction between bearing surfaces of the
threads when threading pipe to fittings.The resulting heat may
expand the pipe threads before the joint is properly made.
When the pipe threads cool and contract in the fitting, the joint
may become loosened causing cooking grease to migrate into
the distribution piping, and/or leakage at the fitting during a
pressure test or agent discharge.
Note:When required to provide pressure testing of pipe or a
system discharge test, it is recommended that all pipe connec-
tions utilize Teflon pipe tape.
5.Install the correct nozzle(s) for each hazard area as previously
designed.Some nozzles are required to be properly oriented
before they are positioned for aiming.
6.Aim the nozzles to a pre-determined aim point in accordance
with the instructions in the “System Design”section.Using the
Nozzle Aiming Device (Part No.431992) will aid in the aiming
process.The device clamps to the nozzle and emits a small
laser light that reflects on the surface where it is aiming.If the
nozzle is used with Swivel Adapter (Part No.418569), the
nozzle with Aiming Device can be rotated to the exact aiming
point and then tightened to hold that angle.
7.Before installing blow-off caps on nozzles, apply a small
amount of Dow Corning No.111 silicone grease across the
opening in the nozzle tip and also a small amount coating the
exterior of the blow-off cap.DONOTFORCESILICONE
GREASEINTONOZZLETIPOPENINGOR FILLCAPWITH

NOTICE
When using old style metal blow-off cap, make
certain the spring clip rotates freely on the metal
cap and coat the outside of the cap, including the
clip, with Dow Corning No.111 silicone grease.
8.Make certain a blow-off cap is in place over each nozzle tip.
These blow-off caps are designed to keep grease from build-
ing-up on the nozzle orifice and inhibiting the agent flow.See
Figure 15.

INSTALLING THE DETECTION SYSTEM
Before the following procedures can be completed, the detection
design must already be completed.These installation instructions
are identical for single, double, and multiple-tank systems except
for the number of hazard areas to be covered.
NOTICE
Inform customer that fusible links should not be
exposed to ammonia-based chemical cleaners
or steam.
1.Based on the requirements listed in the “System Design”
section, mount the detectors in their predetermined locations.
2.Run 1/2 in.conduit from the regulated release mechanism trip
hammer assembly knockout hole to locations selected for
mounting the detectors.
Note:Before assembling the conduit and fittings, make
certain all ends are carefully reamed and blown clear of chips
and scale.Inside of pipe and fittings must be free of oil and
dirt.
When changing the direction of conduit, use only ANSUL
pulley elbows, except, at the top of the regulated release, it is
acceptable to use the “Conduit Offset Assembly”(Part No.
436063).
Note:If stainless steel scissor linkage is used in the system
while using conduit off-set assembly, the following limitations
must be observed:
•Maximum number of elbows – 16
•Maximum number of detectors – 15
•Maximum length of 1/2 in.EMTConduit – 150 ft (45.7 m)
Part No.435546 and 435547 are the “scissor”style series and
terminal detector assemblies.These detector assemblies use
a detector linkage assembly which does not require the wire
rope to be threaded through the linkage assembly while it is
being fed through the detection system.
“Scissor”Style Linkage Installation
1.Secure the conduit to the detector bracket using the two
1/2 in.steel compression fittings on the series detector bracket
or the single 1/2 in.steel compression fitting on the terminal
detector bracket.See Figure 22.
FIGURE 22
000306
NOTICE
Do not use zinc die cast compression connec-
tors on the detection conduit lines as these will
not withstand the normally high temperatures
experienced in the plenum area.
2.For a terminal detector located in a duct or header opening,
secure both sides of the detector bracket with conduit, as
shown in Figure 23.

the hole in the release mechanism locking clamp, allowing the
excess wire rope to hang down.(Do not tighten set screws in
locking clamp at this time.) See Figure 24.
FIGURE 24
000309
4.From the release assembly, run the stainless steel wire rope
through the conduit, pulley elbows and detector brackets to
the terminal detector.
NOTICE
If wire rope requires splicing, make certain
splice is at least 12 in.(30.5 cm) away from any
pulley elbow or conduit adaptor to avoid interfer-
ence.
5.Feed the wire rope through the terminal detector bracket as
shown in Figure 25 or as shown in Figure 26 if the terminal
detector is mounted within a duct or header opening, and
install the stop sleeve approximately 2 to 3 in.(5 to 8 cm) from
the end of the wire rope.See Figure 27.Use the National
Telephone Supply Company Nicopress Sleeve Tool (Stock No.
51-C-887) or equal to properly crimp the stop sleeve.
FIGURE 25
000310
FIGURE 26
000311
FIGURE 27
000312
6.To give a constant tension on the wire rope during installation
of the detector linkage, hang a vice grip or other weighted
device on the excess stainless steel wire rope, leaving an
adequate length of spare wire rope between the locking clamp
and the weighted device.
NOTICE
When attaching the weighted device to the
excess wire rope, allow approximately 3 in.
(8 cm) of wire rope for each detector linkage for
proper installation.
Example:If the system has six detectors, there should be
approximately 18 in.(46 cm) of excess wire rope
between the locking clamp and the weighted
device, which will be utilized when the linkage is
put in place.
7.Install detector scissor assembly as shown in Figure 28.Note
that the ANSUL AUTOMAN or remote release assembly is
located on the left side of the detector bracket.Slightly crimp
the two assembly “boot-hooks”over the cable with pliers so
the cable is captured under each hook but the whole assem-
bly can move from side to side.Center the assembly in the
detector bracket.

INSTALLATIONOFREMOTEMANUALPULLSTATION OR
MECHANICALGASVALVE UTILIZINGFLEXIBLECONDUIT
Flexible conduit allows for quicker installations and the conve-
nience of being able to route the cable over, under and around
obstacles.
Flexible conduit can be used as a substitute for standard EMT
conduit or can be used with EMT conduit.
NOTICE
Flexible conduit can be used only with NEW
remote pull station, Part No.434618, and
mechanical gas valve installations.Flexible
conduit CAN NOT be used in detection
systems.
These instructions address the components and installation of
both the pull station, Part No.434618, and the flexible conduit.
Design Requirements
•Flexible conduit cannot be utilized in detection systems.
•Flexible conduit inserts, Part No.434347, can ONLY be used
with the flexible conduit system.
•The maximum distance from an ANSUL AUTOMAN®Release to
a Pull Station, Part No.434618, is 140 ft (42.7 m) with a
maximum of 360°(for example, 3-90°and 2-45°bends, 2-90°
and 4-45°bends, etc.) bends in the flexible conduit, one pulley
tee (refer to pages 5-17.9 through 5-17.11 for detailed splicing
instructions), two splices, and 15 pulley elbows.
Note:When installing flexible conduit, make sure to feed wire
rope through conduit directly from the spool.DO NOT pre-cut
wire rope.Feeding pre-cut rope through flexible conduit will
cause excessive kinks in the rope, making it difficult to install.
•The maximum distance from an ANSUL AUTOMAN Release to
a mechanical gas valve is 75 ft (22.9 m) with a maximum of 4-
90°bends in the flexible conduit and 4 pulley elbows.
•Any portion of the flexible conduit system can be substituted with
EMT conduit provided the proper connections are used to join
the two types of conduit.
•All bends in the flexible conduit system must have a minimum
bend diameter of 6 in.(15 cm).
•When the flexible conduit is used to make 90°bends between an
ANSULAUTOMAN release and a mechanical gas valve, the
bends must start at the gas valve.No pulley elbows can be used
between the bends.If more than 360°of bends are needed, then
pulley elbows can be used.
•When the flexible conduit is used to make 90°bends between an
ANSULAUTOMANrelease and a pull station, the bends must
start at the ANSULAUTOMANrelease.No pulley elbows can be
used between the bends.If more than 360°of bends are
needed, then pulley elbows can be used.
•When not utilizing a conduit offset, Part No.79825, 2-45°bends
in the flexible conduit are allowed between the strain relief fitting
on top of the ANSULAUTOMAN release, and the location where
the flexible conduit is supported.
•When installing flexible conduit, conduit should be secured at
intervals not to exceed 5 ft (1.5 m) and before and after each
bend.Flexible conduit CANNOT slide in the clamp(s) used for
mounting.Make certain mounting clamp(s) do not pinch the
conduit.The following style clamp (‘P’clip), Part No.436150, is
a suitable type for use on flexible conduit.

Installation Instructions
Note:Do not add any type of lubricants inside or on the flexible
conduit.Make certain stainless steel wire rope is clean and debris-
free.
The flexible conduit should be routed along the same path that
EMT conduit would normally be run.Stainless steel wire rope
should be routed through the flexible conduit as it is in EMT
conduit.
Flexible conduit can be used to connect an ANSUL AUTOMAN
Release to a remote pull station, Part No.434618, or mechanical
gas valves.
Before starting the system installation, take a few minutes to plan
the layout of the system.This will minimize the amount of compo-
nents needed to complete the installation.Once the path of the
flexible conduit has been determined, verify that the layout does
not exceed the design requirements.
Connecting the Flexible Conduit to the ANSUL AUTOMAN
Release,Electrical Junction Box,or MECHANICAL Gas Valve
1.Layout the flexible conduit and secure it in place.Note:If inner
liner is crimped, turn a drywall screw into the end to open it.
See Figure 46.

Pull Station Installation without Pulley Block Assembly
Note 1:When using this installation option,the distance from
the back of the faceplate and the connection to the 1/2 in.EMT
conduit compression fitting must not exceed 6 in.(15.2 cm).
Note 2:To provide for a straight run of wire rope from the pull
station, an octagonal junction box with a center knockout in the
back of the junction box will be needed.See Figure 104a.If a pre-
fabricated box or enclosure is to be used, it must allow the pull

1.Attach a 1/2 in.EMT conduit compression fitting (Part No.
55813) to the back center knock out of the junction box.If
something other than a junction box is to be utilized, a method
of securing the flexible conduit or EMT conduit directly in line
with the center of the pull station pull knob must be used.This
will ensure that in the event of manual operation the wire rope,
exiting the back of the pull station faceplate, will be pulled
straight out without binding or resulting in undue additional pull
force due to friction loss.
2.Remove the block assembly from the pull station face plate.
Thread the wire rope from either flexible conduit or 1/2 in.EMT
conduit attached to the back of the junction box or fabricated
enclosure through the back side of the pull station faceplate
and through the pull knob.

INSTALLING ELECTRICAL SWITCHES
The procedure for field installing an electric (snap-action) switch is
as follows:
NOTICE
Except for the Alarm Initiating Switch, all electri-
cal wiring connections are to be made outside
the ANSUL AUTOMAN Release enclosure in
suitable enclosures in accordance with local
jurisdiction requirements.
1.Make certain that regulated release assembly enclosure cover
is detached with lock bar properly inserted within the regu-
lated release mechanism.
NOTICE
Failure to follow these instructions may lead to
system actuation.
2.Verify that cartridge has been removed from regulated release
assembly and that the regulated release mechanism is in the
cocked position.If regulated release mechanism does not
have lock bar inserted or cartridge removed, refer to the
“Semi-Annual Maintenance,”Page 8-1, in “Maintenance
Examination”section, and complete Steps 2 and 3 before
completing the following installation steps.
If regulated release mechanism has a factory installed sole-
noid, it will also have a factory installed switch.
3.Press each wire assembly onto the 3-terminals located on the
switch(s).Be sure that the connector is pressed tight against
the switch.See Figure 106.
FIGURE 106
001621
4.Install switch(es) to the mounting bracket using provided
fasteners and tighten securely.
5.If more than one switch is being installed, it is necessary to
attach the trip lever extension stud to the trip lever.See Figure
107.Using the provided fasteners, securely install the exten-
sion stud.
6.Raise switch actuating arm squarely over the cam surface of
the trip lever.This will allow the trip lever, when actuated, to
force the actuating arm “UP,”thus reversing the normal condi-
tion of the switch.See Figure 107.
For multiple switch installations, make certain switch actuating
arms are positioned on trip lever extension stud.
Before proceeding with Step 7, test electric (snap-action)
switches:
a.Remove lock bar.With the ANSUL AUTOMAN in the
cocked or ready position, press the lever of each switch up.
If the switch is working properly there should be an audible
click.
b.With the ANSUL AUTOMAN in the fired position, press the
lever of each switch up, there should be no audible click.
When installing multiple switches, make certain all switches
transfer when the release operates.If they do not, readjust
their position.
c.If an audible click is heard in the fired position several
adjustments can be made.The trip lever extension pin can
be rotated so the peak of one of the hex points is pointed
up against the switch levers.Tighten it in that position.If this
doesn’t resolve the problem, loosen the screws holding the
switches, apply a small counterclockwise torque on the
switches and retighten the screws.If necessary, a final
adjustment can be made by removing the snap action
switch and bending the lever slightly.
d.After adjustments repeat steps a and b.Then, recock
ANSUL AUTOMAN and install lock bar.
FIGURE 107
7.The switch may now be connected to compatible components
that are predetermined to shut off or turn on.Refer to compo-
nent manufacturer’s instructions for proper wiring connections
to compatible components.
CAUTION!
Unused wire leads will become “hot”when the system is oper-
ated.Failure to adequately cover exposed wire end(s) will
cause electric shock if touched.
CAUTION!
Before working on any electrical wiring, make certain main
power has been disconnected.Failure to disconnect main
power could cause personal injury or death if contact is made
with energized wires.
CAUTION!
All electrical wiring/connections shall be performed by qualified
individuals in accordance with local jurisdiction requirements.

7-1-09REV.3
After the system has been completely installed, and BEFORE
INSTALLING THE CARTRIDGE,the system must be tested at the
regulated release assembly.The testing information listed in this
section deals with the limitations and parameters of this pre-engi-
neered system.Those individuals responsible for the testing of the
R-102 system must be trained and hold a current ANSUL certifi-
cate in an R-102 training program.
Note:ANSULAUTOMAN Release must be in the cocked position
before testing manual pull station.Make certain to remove lock bar
before performing pull station testing.
TESTINGMANUALPULLSTATION
To test each remote manual pull station, complete the following
steps:
1.With the expellant gas cartridge removed, remove lock bar
from regulated release assembly cable lever.
2.On pull station, remove break rod from the pull station by
inserting a small screwdriver into slot at bottom of pull knob to
facilitate turning the pull knob.Push slightly on the screwdriver
and turn pull knob clockwise, then the pull knob can be
removed without breaking the glass rod.
NOTICE
Take care in removing the break rod from the
pull station side shields while rotating the break
rod/pull knob assembly.
3.Pull ring handle on pull station.If the regulated release
assembly is tripped easily, the remote manual pull station is
properly installed.If the regulated release assembly does not
trip, remove pulley tee (if provided) and each pulley elbow
cover to make certain wire rope is resting on the pulley
sheave.If this does not correct the problem, there is too much
slack in the line and it must be retightened.
4.Recock regulated release assembly using cocking lever (Part
No.14995 or 435603) and reinstall lock bar(Part No.14985).
5.On pull station, insert the break rod into the two holes toward
the top of the pull knob.Rotate the pull knob counterclockwise.
NOTICE
Take care in snapping in the ends of the break
rod into the pull station side shields while rotat-
ing the entire assembly.
NOTICE
If no other devices are being attached, proceed
to Page 6-3, Step No.1, and test the detection
system.
TESTING MECHANICAL GAS VALVES
To test each mechanical gas shut-off valve complete the following
steps:
1.
Turn gas line on.
2.Manually push each air cylinder rod to full ‘‘DOWN’’position.
The gas valve should close.If mechanical gas valve does not
trip, remove each pulley elbow cover to make certain wire rope
is resting on each pulley elbow sheave.If this does not correct
the problem there may be too much slack in the line and it
should be retightened.
3.Test for gas leaks by painting connections with a soap solu-
tion.Bubbles indicate a gas leak.Tighten connections where
leaks appear and repeat test again to make certain no other
gas leaks exist.
4.If no gas leak is found, pull air cylinder rod to full ‘‘UP’’position.

UL EX3470ULC EX3470Page 7-1
7-1-98REV.1
The recharge information listed in this section deals with the limi-
tations and parameters of this pre-engineered system.Those indi-
viduals responsible for the recharge of the R-102 system must be
trained and hold a current ANSUL certificate in an R-102 training
program.
For continued fire protection,the R-102 restaurant fire sup-
pression system must be recharged immediately after use.
Recharge procedures for single, double, and multiple-tank sys-
tems are as follows.
CLEANUP PROCEDURES
Although there is no unusual cleanup procedure of ANSULEX or
ANSULEX Low pH agents, due to the alkaline nature of these
agents, they should be cleaned from kitchen surfaces within 24
hours after system discharge.The reaction from the wet chemical
agent on cooking grease or oil produces a foamy bi-product that
can be wiped up with a cloth or sponge.The following procedures
should be followed:
1.The agent is non-toxic;however, food product and cooking
grease/oil that has come in contact with the agent will no
longer be suitable for human consumption and should be dis-
carded.
2.Sponge up as much of the agent as possible using sponges
or clean rags.Dispose of these sponges or rags in a local san-
itary land fill site in accordance to local authorities.Note:Wear
rubber gloves during cleanup as sensitive skin may become
irritated.If the ANSULEX agent or its residue comes in contact
with skin or eyes, flush thoroughly with clean water.
3.Using hot, soapy water and either a clean cloth or sponge,
wipe away all foamy residue and thoroughly scrub all surfaces
that have come in contact with the agent.Note:Wear rubber
gloves during cleanup as sensitive skin may become irritated.
If the ANSULEX agent or its residue comes in contact with
skin or eyes, flush thoroughly with clean water.
4.After thoroughly cleaning all affected surfaces, adequately
rinse and allow to completely dry before re-energizing the
equipment.
RECHARGE
NOTICE
Determine the cause of system discharge and
correct immediately before performing system
recharge.
1.Remove the enclosure cover from the ANSUL AUTOMAN
regulated release assembly and each regulated actuator
assembly.

residue.To prepare the system for flushing:
a.Pour the complete contents of one 32-oz.bottle of ANSUL
Flushing Concentrate (Part No.79656) into an empty
R-102 agent tank.One complete bottle is used for either
size tank, the 1.5 gallon or the 3.0 gallon.
b.Fill the tank approximately half full with warm, clean water.
Agitate the tank for a few seconds and then add more warm
water to bring the fill level to within approximately
1 in.(2.5 cm) from the bottom of the fill opening.
CAUTION!
Do not flush pipe with only water or other non-approved
material, as this could cause internal corrosion, leading to
possible improper discharge.
CAUTION!
Before attempting any cleanup, make certain that all fuel
sources to the equipment to be cleaned have been shut off.
Make certain that the exhaust hood and all appliance electrical
controls have been de-energized to avoid any chance of elec-
trical shock resulting from the cleaning process or from electri-
cally conductive alkaline liquid agent and/or its residue.
Make certain all surfaces to be cleaned have cooled down to
room temperature.
Do not use water to clean any appliances that contain hot
grease or cooking oils.Doing so may result in violent steaming
and/or spattering.

SECTIONVIII–MAINTENANCE EXAMINATION
UL EX3470ULC EX3470Page 8-1
7-1-09REV.8
The maintenance information listed in this section deals with the
limitations and parameters of this pre-engineered system.Those
individuals responsible for the maintenance of the R-102 system
must be trained and hold a current ANSUL certificate in an R-102
training program.
Maintenance is required semi-annually.At the 12 year interval,
along with the normal maintenance exam, the tank(s) must be
hydro-tested and the regulator(s) must be flow tested.
Prior to performing the required maintenance steps, verify that the
R-102 system protection is designed and installed correctly for the
existing appliance and ventilation system configuration.If not,
make corrections as required.
SEMI-ANNUAL MAINTENANCE EXAMINATION
Semi-annual maintenance procedures for single, double, and
multiple-tank systems are as follows.
NOTICE
Under certain circumstances hood and duct
cleaning operations may render the fire
suppression system ineffective due to a coating
of cleaning chemical left on the detection equip-
ment or mishandling of the system by cleaning
service personnel.Therefore,it is strongly
recommended that the R-102 system be
completely inspected and serviced by an
authorized ANSUL distributor immediately
following any such cleaning operations.
1.Remove the enclosure cover from the ANSUL AUTOMAN
regulated release assembly and each regulated actuator
assembly.
2.Insert the lock bar (Part No.14985) on the cocked regulated
release mechanism.See Figure 1.
FIGURE 1
000321
3.Remove cartridge from regulated release assembly and each
regulated actuator assembly, install safety shipping cap, and
set aside in a safe location.
4.Check to make certain the actuation line used to connect the
regulated actuator assembly(s) to the ANSUL AUTOMAN
regulated release assembly is connected to the high pressure
side (right side) of the cartridge receiver in the ANSUL
AUTOMAN and that it is intact, with all fittings securely tight-
ened.This includes any 1/8 in.copper tubing and fittings used
to connect to the air cylinder for the ANSUL mechanical gas
valve.
5.To check for leaks in the actuation line, a hand held or electric
vacuum pump may be used:
a.Disconnect the actuation line from the ANSUL AUTOMAN
regulated release cartridge receiver and connect the pump
to the line.
b.The pump should pull a vacuum to 20 inches of mercury, as
shown on the gauge.Leaks should not exceed 5 inches of
mercury loss within a 30 second time frame.
c.If the gauge indicates a leak in the line, examine for loose
connections or damage.Repair or replace as needed.
d.If leakage is not due to piping, disassemble the pneumatic
actuator assembly(s) in the regulated actuator(s) and
inspect the actuator and the O-ring in the actuator.Repair
or replace as needed.
Note:Vacuum pumps can be obtained from automotive
parts/supply stores.
Alternate Test Method:
The actuation line can also be pressurized with either CO2 or
N2 from a cartridge or with dry air, CO2, or N2 from a larger
cylinder.
a.Cock the ANSUL AUTOMAN regulated release assembly
and carefully insert Lock Bar, Part No.14985.See Figure 8.
b.Make certain expellant gas line hose and/or pipe from the
regulator in the ANSUL AUTOMAN regulated release is
disconnected from agent storage tanks.
c.Connect Regulator Test Kit, Part No.56972, to one of the
expellant gas line hoses and securely cap the remaining
hose or pipe.See Figure 10.
d.Verify that no cartridges are installed in the ANSUL
AUTOMAN or the regulated actuator assembly(s).
e.To verify operation of the regulated actuator assembly(s),
Pressure Adaptor, Part No.427560, can be used to
connect to a pressurized CO2 or N2 cylinder, instead of

In addition to performing all the steps necessary for Semi-Annual
Maintenance, disconnect the agent discharge piping from the
storage tank outlet(s) and verify that the agent distribution piping
is not obstructed.
1.At least annually, use dry air or nitrogen and blow through the
agent distribution piping with the nozzle blow-off caps
removed, verifying that dry air or nitrogen is discharging at
each nozzle location.
2.At least annually, all rubber nozzle blow-off caps must be
replaced.
12-YEAR MAINTENANCE EXAMINATION
In addition to performing all of the steps necessary for semi-annual
and annual maintenance, the following twelve-year maintenance
procedures for single, double, and multiple-tank systems must be
performed.
NOTICE
Under certain circumstances hood and duct clean-
ing operations may render your fire suppression
system ineffective due to a coating of cleaning
chemical left on the detection equipment or
mishandling of the system by cleaning service
personnel.
Therefore,it is strongly recommended that the
R-102 system be completely inspected and
serviced by an authorized ANSUL distributor
immediately following any such cleaning oper-
ations.
At twelve-year intervals, the liquid agent tank(s)
must be hydrostatically tested and refilled with a
fresh charge of ANSULEX Low pH Liquid Fire
Suppressant.The date of manufacture is stamped
on the bottom of the agent tank or on the tank label.
1.Remove the enclosure cover from the ANSUL AUTOMAN
regulated release assembly and each regulated actuator
assembly.
2.Insert the lock bar (Part No.14985) on the cocked regulated
release mechanism.See Figure 8.
FIGURE 8
000321
3.Remove cartridge from regulated release assembly and each
regulated actuator assembly, install safety shipping cap, and
set aside in a safe location.
4.Remove gasket from cartridge receiver in regulated release
mechanism and each regulated actuator.Check gasket for
elasticity or cuts and replace if necessary.Clean and coat
gasket lightly with a good grade of extreme temperature
grease.Reinstall gasket into cartridge receiver(s).
5.From tank in enclosure:Disconnect the expellant gas piping or
hose from each tank adaptor assembly.
From tank in bracket assembly:Disconnect expellant gas
piping union at each tank adaptor inlet line.
6.Disconnect distribution piping union at each tank adaptor
outlet line.
7.From tank in enclosure:Remove tank.
From tank in bracket assembly:Loosen wingnut, disengage
bracket band, and remove each tank.Keep tank in upright
position to avoid spilling the agent.
8.Loosen tank adaptor/tube assembly and remove.
9.
Pour the liquid agent from the tank into a clean, plastic
container, and flush tank with clear water.
10.At this point, each liquid agent tank, including the 1/4 in.
gas hose assembly, must be HYDROSTATICALLY TESTED to
330 psi (26.6 bar).Refer to “Hydrostatic Test Instructions,”
F-7602, for test adaptors and instructions.
NOTICE
DO NOT hydrostatically test a red painted mild
steel agent storage tank.Instead, replace the
tank with a new stainless steel tank shipping
assembly (3-Gallon, Part No.429862, or 1.5
Gallon, Part No.429864).
11.Verify date stamped on cartridge.The cartridge must also be
hydrotested at intervals not greater than 12 years.(European
cartridges are not refillable, therefore cannot be hydrotested
and refilled.They must be discarded).
12.If cartridge date indicates the need for hydrotesting, the
cartridge must be bled down through normal ANSUL
AUTOMAN release operation, returned to ANSUL for credit (or
hydrotested by properly trained and ANSUL Authorized
cartridge refilling stations), and replaced with a charged,
replacement cartridge.
CAUTION!
Do not reinstall cartridge at this time or system may be
actuated.
CAUTION!
Safety glasses should be worn during transfer operations
of ANSULEX Low pH Liquid Fire Suppressant.Avoid
contact with skin or eyes.In case of contact, flush imme-
diately with water for 15 minutes.If irritation persists,
contact a physician.Do not take internally.If taken inter-
nally do not induce vomiting.Dilute with water or milk and

Multiple Nozzle Fryer Protection Calculation Examples
Example No.1 – Donut Fryer Without Dripboard.This fryer has
a frypot that measures 26 in.in depth x 28 in.in length (66 x 71
cm).Because the frypot exceeds the maximum dimensions for
one nozzle, multiple nozzles will be required.
Procedure:Find the area of the fryer by multiplying the 26 in.
depth x the 28 in.length (66 x 71 cm) which equals
728 sq in.(4697 sq cm).Using the 3N nozzle
(approved for fryers with the longest side of 25 3/8 in.
(64 cm) and a maximum of 370.5 sq in.(2390 sq cm)
in area), divide the total area of 728 sq.in.(4697 sq.
cm) by 370.5 sq in.(2390 sq cm) to find the number
of nozzles needed.728 sq.in.(4697 sq cm) divided
by 370.5 sq in.(2390 sq cm) per nozzle=2 nozzles
required.Then verify the maximum longest side
dimension of 25 3/8 in.(64 cm).Doing this will
require doubling the 3N nozzles to =a total of 4
nozzles,if we are to protect the 26 in.(66 cm) depth
and the 28 in.(71 cm) length of the fryer with this 3N
nozzle option.See Figure 1.
Using the same process, but utilizing the 3N nozzle
approved for fryer protection with the longest side of
27 5/8 in.(70 cm) and the maximum of 324 sq in.
(2090 sq cm) in area, the calculation will change to
728 sq in.(4697 sq cm) divided by 324 sq.in.(2090
sq.cm) per nozzle =3 nozzles.Because this 3N
nozzle option will protect 27 5/8 in.(70 cm) on the
longest side, it will protect the 26 in.(66 cm) side in
this example, thus eliminating the need for extra noz-
zles.Utilizing this option, in this example, will require
a total of 9 flows, but allows less nozzles and less
nozzle drops*.See Figure 1.
*Note:2-flow appliance nozzles can also be used.
This option requires a total of 4 nozzles (728 sq in.
divided by 210 sq in.per nozzle=4 nozzles, or 8
total flows).Using this option requires that the noz-
zles be placed over each quadrant of frypot area pro-
tected and aimed to the center of the modules.This
option may be desirable if minimizing total system
flows is important.
FIGURE 1
002466
Example No.2 – Fryer With Dripboard.This fryer has an overall
fry vat, including a dripboard, that measures 24 in.(61 cm) in
depth x 20 in.(51 cm) in length.The actual frypot measures 20 in.
x 20 in.(51 cm x 51 cm).Because both the frypot and the overall
fry vat including the dripboard exceed the maximum dimensions
for one nozzle, multiple nozzles will be required.
Procedure:Divide the fryer cooking area from left to right or from
front to back into modules that do not exceed single
nozzle area limitations and longest side limitations as
described in the table for “Fryer Multiple Nozzle
Protection”located in the Design Section.
The example fryer can either be divided from left to
right into two modules, each measuring 10 in.x 24 in.
(25.4 cm x 61 cm), or it can be divided from front to
back.See Figure 2.
If the fryer is divided from front to back, two 2-flow
nozzles may be adequate.To determine this, first
protect as much of the rear portion of the vat (the fry-
pot area) that is allowed with 2-flow appliance noz-
zles using the maximum area of 210 sq in.(1355
sqcm) per nozzle with the maximum longest side of
21in.(53 cm) for multiple nozzles.See Figure 2.
In the example, the frypot is 20 in.(51 cm) from side
to side.Use the maximum area of 210 sq in.(1355
sqcm) allowed for one nozzle and divide it by 20 in.
(51cm), a total of 10 1/2 in.(27 cm) of the frypot can
be protected with one 2-flow nozzle (210 sq in.divid-
ed by 20 in.= 10.5 in.).See Figure 2.
This leaves the remainder of 9 1/2 in.(24 cm) of frypot
and the entire dripboard yet to protect.One 2-flow
appliance nozzle will protect up to 10 1/2 in.(27 cm) of
frypot, therefore, there is no need to verify the remain-
ing 9 1/2 in.(24 cm).There is only the overall of 9 1/2
in.(24 cm) remaining plus the dripboard to verify.
The dripboard measures 4 in.x 20 in.(10 cm x 51
cm), with an overall remainder of frypot+dripboard
area size of 13 1/2 in.x 20 in.(34 cm x 51 cm)=270
sq in.(1742 sq cm).Reviewing the “Multiple Nozzle
Fryer Table,”a 2-flow appliance nozzle can protect an
area, including dripboard, of 294 sq in.(1897 sq cm)
with a longest side of 21 in.(53 cm).Because the
area is less than the maximum of 294 sq in.(1897 sq
cm) and the longest side is less than the maximum
of 21 in.(53 cm), a 2-flow nozzle will be sufficient.
See Figure 2.
Adding the protection required for the back of the fry-
pot to the front protection requires two 2-flow appli-
ance nozzles as a minimum.See Figure 2.

WIRINGDIAGRAM
NFPA standards require simultaneous operation for fire suppres-
sion systems when two or more hazards can be simultaneously
involved in fire by reason of their proximity.To accomplish simulta-
neous operation, the 120 VAC Electric AUTOMAN Regulated
Release Assembly can be used.This release can be activated
independently by fusible line operation exactly like the mechanical
version and can also be triggered electrically using a snap action
switch from another 120 VAC Electric AUTOMAN Regulated
Release Assembly or a Mechanical AUTOMAN Regulated
Release Assembly.The electrical wiring used to connect from one
AUTOMAN Regulated Release Assembly to another will not be
supervised.However, NFPA 96 allows an exception for electrically
operated systems which “include automatic mechanical detection
(fusible link) and actuation as a backup detection system.”
In the case of multiple hoods sharing a common exhaust duct,
NFPA 17A requires one of two forms of simultaneous operation.
The following wiring diagrams (See Figures 3 and 4) identify two
principle uses for the 120 VAC Electric AUTOMAN Regulated
Release Assembly.Refer to Components Section, Page 3-1,
Figure 3.
1.Simultaneous operation of all independent hood, duct, and
appliance protection systems.See Figure 3.
2.Simultaneous operation of any hood, duct, and appliance pro-
tection system and the system(s) protecting the entire common
exhaust duct.See Figure 4.
