The amount of air in the expansion chamber will not change over time. The pressure, temperature, and volume of the air at different times will be related in accordance with this formula. The antifreeze in the system is essentially incompressible, so the air volume in the expansion chamber will decrease by an amount equal to the expansion of the antifreeze. It is assumed that there is no trapped air in the system piping, so the only air in the system is in the expansion chamber. This is a conservative assumption, since more air is better. In reality, there will be at least some trapped air. However, only the air in the expansion chamber can be relied upon to be available when needed. At precharge, the chamber will be completely full of air. NFPA 13 (02) 1Density is based on -100F for 50% propylene glycol and is an estimate of the lowest expected temperature of the mixture in the entire system for a ranch style house. A higher temperature might be expected for a tri-level home. Use density for glycerine under the same conditions 2 Density is based on 1300F for 50% propylene glycol and is an estimate of the highest expected temperature of the mixture in the entire system for a ranch style house. A lower temperature might be expected for a tri-level home. Use density for glycerine under the same conditions 3 It is believed that values for V cancel since the total volume within the chamber does not change 4 The pre-charge pressure will be the same as static pressure at the street or pump churn pressure 5 The maximum allowable working pressure is the same as the maximum listed pressure for the sprinkler heads 6 The temperature chosen is based on expansion tanks installed in heated basements Revised 12/06/05 7 Density values come from Fig 7.5.2.5 (a-c) Pg 33-34 8 Left column = glycol; right column = glycerine 60% (-10 to 130) 9 Add 15 to all pressure values to include atmospheric pressure 10Add 459 to F to change to R ~G~L Pumps Series NPE Size 1 x 11/4-6 Pump Performance Curves METERS 50 150 140 40 ~ 120 '" ~ u 30 100 ~ -< ~ :g 80 0 20 60 40 10 20 0 NOTE: NOl f(!comrnen ded for operation beyond [,),inlCli H-G c:Jrve PSI 67.5 64.5 6/·D 3500 RPM 61>/11 D JO '2.0 30 so 0 10 20 30 40 50 60 Ii S.

The Cover Plate/Retainer Assembly con- ceals the sprinkler operating compo- nents above the ceiling. The flat profil of the Cover Plate provides the optimum aesthetically appealing sprinkler design. Additionally, the concealed design of the Series LFII Residential Flat-Plate Con- cealed Pendent Sprinklers provides 1/2 inch (12,8 mm) vertical adjustment. This adjustment provides a measure of flex ibility when cutting fixed pipe drops. The Series LFII Residential Flat-Plate Concealed Pendent Sprinklers are in- tended for use in the following systems: • per NFPA 13D, wet pipe residential sprinkler systems for one- and two- family dwellings and mobile homes; • per NFPA 13R, wet pipe residential sprinkler systems for residential oc- cupancies up to and including four stories in height; and • per NFPA 13, wet pipe sprinkler sys- tems for the residential portions of any occupancy. The Series LFII Residential Flat-Plate Concealed Pendent Sprinkler has a 4.9 (60,5) K-factor that provides the required residential flow rates at reduced pres sures, enabling smaller pipe sizes and water supply requirements. This sprinkler has been designed with heat sensitivity and water distribution characteristics proven to help in the con- trol of residential fires and to improve the chance for occupants to escape or be evacuated. The Series LFII Residential Flat-Plate Concealed Pendent Sprinklers are shipped with a Disposable Protective Cap. The Protective Cap protects the sprinkler during ceiling installation or finish. After ceiling installation is com plete, the Protective Cap is removed and the Cover Plate/Retainer Assem- bly is installed. Removing the Protec- tive Cap is required for proper sprinkler performance. NOTICE The Series LFII Residential Flat-Plate Concealed Pendent Sprinklers (TY2524) described herein must be installed and maintained in compliance with this doc- ument and with the applicable standards of the National Fire Protection Associa- tion, in addition to the standards of any authorities having jurisdiction. Failure to do so may impair the performance of these devices. Owners are responsible for maintaining their fire protection system and devices in proper operating condition. The in- stalling contractor or sprinkler manu- facturer should be contacted with any questions.

At this point, the Deflector, sup ported by the Guide Pins, drops down to its operated position. The Solder Link Element of the Sprinkler/ Support Cup Assembly is comprised of two link halves that are soldered togeth- er with a thin layer of solder. When the rated temperature is reached, the sol- der melts and the two link halves sepa- rate, allowing the sprinkler to activate and flow water. 1 Registered trademark of Dupont Design Criteria The TYCO RAPID RESPONSE Series LFII Residential Flat-Plate Concealed Pendent Sprinklers (TY2524) are UL and C-UL Listed for installation in ac- cordance with the following criteria. NOTICE When conditions exist that are outside the scope of the provided criteria, re- fer to the Residential Sprinkler Design Guide TFP490 for the manufacturer's recommendations that may be accept- able to the Authority Having Jurisdiction. The Series LFII Residential Flat-Plate Concealed Pendent Sprinklers must not be used in applications where the air pressure above the ceiling is greater than that below. Down drafts through the Support Cup can delay sprinkler op- eration in a fire situation System Type Only wet pipe systems may be utilized. Hydraulic Design Table A provides the minimum required sprinkler flow rate for systems designed to NFPA 13D or NFPA 13R as a function of temperature rating and the maximum allowable coverage areas. The sprinkler flow rate is the minimum required dis charge from each of the total number of “design sprinklers” as specified in NFPA 13D or NFPA 13R. For systems designed to NFPA 13, the number of design sprinklers is to be the four most hydraulically demanding sprinklers. The minimum required dis- charge from each of the four sprinklers is to be the greater of the following: • flow rates given in Table A for NFPA 13D and 13R as a function of tem- perature rating and the maximum al- lowable coverage area • minimum discharge of 0.1 GPM/ sq. ft. over the “design area” com- prised of the four most hydraulically demanding sprinklers for actual cov- erage areas protected by the four sprinklers Obstruction To Water Distribution Locate sprinklers in accordance with the obstruction rules of NFPA for residential sprinklers as well as obstruction criteria described within TYCO technical data sheet TFP490. Operational Sensitivity Install sprinklers relative to the ceiling mounting surface as shown in Figure 3. Sprinkler Spacing The minimum spacing between sprin- klers is 8 feet (2,4 m). The maximum spacing between sprin- klers cannot exceed the length of the coverage area (Table A) being hydrau- lically calculated; for example, a maxi- mum of 12 feet for a 12 ft. x 12 ft. cov- erage area or 20 feet for a 20 ft. x 20 ft. coverage area. (a) For coverage area dimensions less than or between those indicated, use the minimum required flow for the next highest coverage area for which Hydraulic Design section under the Design Criteria are stated. (b) The Minimum Flow requirement is based on minimum flow in GPM (LPM) from each sprinkler. The associated residual pressures are calculated using the nominal K-factor. Refer to “Hydraulic Design” in the Design Criteria section for details.

NOTICE Damage to the Solder Link Element dur- ing installation can be avoided by han- dling the sprinkler by the Support Cup only; that is, do not apply pressure to the Solder Link Element (Figure 1). Obtain a leak-tight 1/2 inch NPT sprinkler joint by applying a minimum-to-maxi- mum torque of 7 to 14 ft.-lbs. (9,5 to 19,0 Nm). Higher levels of torque can distort the sprinkler inlet with consequent leak- age or impairment of the sprinkler. Do not attempt to compensate for in- sufficient adjustment in the Cover Plate Retainer Assembly by under- or over- tightening the sprinkler. Re-adjust the position of the sprinkler fitting to suit 1. Install pendent sprinklers in the pendent position, with the center- line of the sprinkler perpendicular to the mounting surface. 2. Remove the Protective Cap. 3. With pipe-thread sealant applied to the pipe threads, and using the W-Type 18 Wrench shown in Figure 2, install and tighten the Sprinkler/ Support Cup Assembly into the fit ting. The W-Type 18 Wrench ac- cepts a 1/2 inch ratchet drive. 4. Replace the Protective Cap by pushing it upwards until it bottoms out against the Support Cup. The Protective Cap helps prevent dam- age to the Deflector and Guide Pins during ceiling installation and/ or during application of the finish coating of the ceiling. NOTICE As long as the protective Cap re- mains in place, the system is con- sidered “Out Of Service”. 5. After the ceiling has been com- pleted with the 2-1/2 inch (63 mm) diameter clearance hole and in preparation for installing the Cover Plate/Retainer Assembly, remove and discard the Protective Cap, and verify that the Deflector moves up and down freely. If the Sprinkler has been damaged and the Deflector does not move up and down freely, replace the entire Sprinkler assembly. Do not attempt to modify or repair a damaged sprinkler. 6. Screw on the Cover Plate/Retainer Assembly until its flange contacts the ceiling. Do not continue to screw on the Cover Plate/Retainer Assembly such that it lifts a ceiling panel out of its normal position. If the Cover Plate/Retainer Assembly cannot be engaged with the Mounting Cup or the Cover Plate/Retainer As- sembly cannot be engaged sufficiently to contact the ceiling, the Sprinkler Fitting must be repositioned. Care and Maintenance The TYCO RAPID RESPONSE Series LFII Residential Flat-Plate Concealed Pendent Sprinkler (TY2524) must be maintained and serviced in accordance with the following instructions. NOTICE Before closing a fire protection system main control valve for maintenance work on the fire protection system that it con trols, obtain permission to shut down the affected fire protection system from the proper authorities and notify all person- nel who may be affected by this action. When properly installed, there is a nomi- nal 1/8 inch (3,2 mm) air gap between the lip of the Cover Plate and the ceil- ing, as shown in Figure 3. This air gap is necessary for proper operation of the sprinkler by allowing heat flow from a fire to pass below and above the Cover Plate to help assure appropriate release of the Cover Plate in a fire situation. If the ceiling needs repainting after sprinkler installation, exercise care to ensure that the new paint does NOT seal off any of the air gap. Failure to do so may impair sprinkler operation. Absence of a Cover Plate can delay the sprinkler operation in a fire situation Do not pull the Cover Plate relative to the Enclosure. Separation may result. Exercise care to avoid damage to sprin- klers before, during, and after installa- tion. Never paint, plate, coat, or other- wise alter automatic sprinklers after they leave the factory. Never repaint factory-painted Cover Plates. When necessary, replace cover plates with factory-painted units. Non- factory applied paint can adversely de- lay or prevent sprinkler operation in the event of a fire Replace sprinklers that: • were damaged by dropping, striking, wrench twisting, wrench slippage, or the like. • were modified or over-heated • are leaking or exhibiting visible signs of corrosion. Responsibility lies with owners for the inspection, testing, and maintenance of their fire protection system and devices in compliance with this document, as well as with the applicable standards of the National Fire Protection Association (for example, NFPA 25), in addition to the standards of any other authorities having jurisdiction. Contact the install- ing contractor or sprinkler manufacturer regarding any questions. Automatic sprinkler systems are rec- ommended to be inspected, tested, and maintained by a qualified Inspec tion Service in accordance with local requirements and/or national codes.

TYPICAL APPLICATION Typical pressure reducing valve station using two Model ZW109 in parallel to handle a wide range of fow rates. Larger Model ZW109 valve takes care of peak loads and smaller Model ZW109 handles low fows. Suggested fow calculations are based on fow through Schedule 40 Pipe. Maximum continuous fow is approx. 20 ft./sec (6.1 meters/sec) & maximum intermittent is approx. 25 ft./sec (7.6 meters/sec) and minimum continuous fow is approx. 1 ft./sec (0.3 meters/sec). The Model ZW109 utilizes a pressure reducing pilot valve that installs on the discharge side of the control circuitry. The pilot is a direct acting, normally open, spring loaded, diaphragm actuated valve; the spring being adjustable within a 10:1 ratio. The operation of the ZW109 begins with accurately sizing the valve, then fne tuning the control circuit by adjusting the pilot spring to the desired downstream pressure. Inlet pressure is piped to the inlet port of the pressure reducing pilot. A sensing line runs internally from the discharge side of the pilot to its lower control chamber under the diaphragm. Thus, downstream pressure exceeding the preset acts to close the pilot while the adjustable spring seeks to keep it open. The result is a modulating action in the pilot that is transmitted to the bonnet of the main valve. This creates a mirror modulation of the diaphragm assembly in the main valve. Downstream pressure is maintained within narrow limits regardless of changing fow rates or varying inlet pressures.
