1. DESCRIPTION
Viking Mirage® Standard and Quick Response Concealed Pendent Sprinkler VK462 and HP Sprinkler VK463 are thermosensitive glass-bulb spray sprinklers designed for installation on concealed pipe systems where the appearance of a smooth ceiling is desired.
The sprinkler is pre-assembled with a threaded adapter for installation with a low-pro-file cover assembly that provides up to ½” (12.7 mm) of vertical adjustment. The two-piece design allows installation and testing of the sprinkler prior to installation of the cover plate. The “push-on”, “thread-off” design of the concealed cover plate assembly allows easy installation of the cover plate after the system has been tested and the ceiling finish has been applied. The cover assembly can be removed and reinstalled, allowing temporary removal of ceiling panels without taking the sprinkler system out of service or removing the sprinkler. The Electroless Nickel PTFE (ENT) coating has been investigated for installation in corrosive atmospheres and is cULus Listed as cor-rosion resistant as indicated in the Approval Charts. The ENT finish is only available for the sprinkler assembly, the cover plate is not plated.

4. INSTALLATIONRefer to appropriate NFPA Installation Standards.
5. OPERATION
During fire conditions, when the temperature around the sprinkler approaches its operating temperature, the cover plate detaches.
Continued heating of the exposed sprinkler causes the heat-sensitive liquid in the glass bulb to expand and the bulb to shatter, releasing the yoke, pip-cap and sealing spring assembly. Water flowing through the sprinkler orifice strikes the sprinkler deflector,
forming a uniform spray pattern to extinguish or control the fire.

Other limits may apply, depending on fire loading, sprinkler location, and other requirements of the Authority Having Jurisdiction. Refer to specific installation standards.3 The corrosion-resistant coatings have passed the standard corrosion test required by the approving agencies indicated on pages 51c-e. These tests cannot and do not represent all possible corrosive environments. Prior to installation, verify through the end-user that the coatings are compatible with or suitable for the proposed environment. For automatic sprinklers, the coatings indicated are applied to the exposed exterior surfaces only. Note that the spring is exposed on sprinklers with Polyester, ENT, and PTFE coatings. For ENT coated automatic sprinklers, the waterway is coated.

General
Description
TYCO Series DS-C Dry Type Sprinklers, 5.6K Concealed Pendent, Standard (5 mm Bulb) and Quick Response (3 mm Bulb) and Standard Coverage, are decorative sprinklers featuring a flat cover plate designed to conceal the sprinkler. This type of sprinkler is typically used to provide a sprinkler drop from an unheated attic into an area where aesthetics is a concern, such as nursing homes, restaurants, and schools.
Each unit includes a Cover Plate Assembly that conceals the sprinkler operating components above the ceiling. The separable two-piece design of the Cover Plate and Support Cup Assemblies allows installation of the sprinklers and pressure testing of the fire protection system prior to installation of a suspended ceiling or application of the finish coating to a fixed ceiling. They also permit removal of suspended ceiling panels for access to building service equipment without having to first shut down the fire protec-tion system and remove sprinklers. Also, the separable two-piece design of the Sprinkler provides for 1/2 inch (12,7 mm) of vertical adjustment.
Series DS-C Sprinklers are shipped with a Disposable Protective Cap. The Protective Cap is temporarily removed for installation, and then it can be replaced to help protect the sprinkler while the ceiling is installed or finished. The tip of the Protective Cap
can also be used to mark the center of the ceiling hole into plaster board and ceiling tiles by gently pushing the ceiling product against the Protective Cap. When the ceiling installation is complete the Protective Cap is removed and the Cover Plate Assembly installed.
NOTICE
Series DS-C Dry Type Concealed Pendent Sprinklers described herein must be installed and maintained in compliance with this document and the applicable standards of the National Fire Protection Association, in addition to the standards of any authorities having jurisdiction. Failure to do so may impair the performance of these devices.
The owner is responsible for main-taining their fire protection system and devices in proper operating condition. The installing contractor or sprinkler manufacturer should be contacted with any questions.
Series DS-C Dry Type Concealed Pendent Sprinklers must only be installed in fittings that meet the requirements of the Design Criteria section.

Operation
When TYCO Series DS-C Dry Type Concealed Pendent Sprinklers is in service, water is prevented from entering the assembly by the Plug with Gasketed Spring Plate Seal (Figure 1) in the Inlet of the Sprinkler.
When exposed to heat from a fire, the Cover Plate, which is normally soldered to the Retainer at three points, falls away to expose the Sprinkler Assembly. At this point the Deflector supported by the Guide Pins drops down to its opera-tional position.
The glass bulb contains a fluid that expands when exposed to heat. When the rated temperature is reached, the fluid expands sufficiently to shatter the glass bulb, and the Bulb Seat is released.
The compressed Spring is then able to expand and push the Water Tube as well as the Guide Tube outward. This action simultaneously pulls inward on the Yoke, withdrawing the Plug with Gasketed Spring Plate Seal, from the Inlet, allowing the sprinkler to activate and flow water.

Criteria
TYCO Series DS-C 3 mm bulb-type Dry Type Concealed Pendent Sprinklers (TY3535) are UL and C-UL Listed as quick response, standard spray sprinklers for use in accordance with the current NFPA standard.
Series DS-C 5 mm bulb-type Dry Type Concealed Pendent Sprinklers (TY3555) are UL and C-UL Listed as standard response, standard spray sprinklers for use in accordance with the current NFPA standard.
Series DS-C Dry Type Sprinklers are only listed when installed with Series RFII Concealed Cover Plates having a factory-applied painted or metallic finish.
Series DS-C Dry Type 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 could delay sprinkler operation in a fire situation.
Sprinkler FittingsInstall 1 inch NPT Series DS-C Dry Type Concealed Pendent Sprinklers in the 1 inch NPT outlet or run of the following fittings:
• malleable or ductile iron threaded tee fittings that meet the dimen-sional requirements of ANSI B16.3 (Class 150)
• cast iron threaded tee fittings that meet the dimensional requirements of ANSI B16.4 (Class 125)
Do not install Series DS-C Dry Type Concealed Pendent Sprinklers into elbow fittings. The Inlet of the sprinkler can contact the interior of the elbow.
The unused outlet of the threaded tee is plugged as shown in Figures 5 and 6.
You can also install Series DS-C Dry- Type Sprinklers in the outlet.
The configuration shown in Figure 5 is only applicable for wet pipe systems where the sprinkler fitting and water-filled pipe above the sprinkler fitting are not subject to freezing and where the length of the Dry Type Sprinkler has the minimum exposure length depicted in Figure 7. Refer to the Exposure Length section.
For wet pipe system installations of 1 inch NPT Series DS-C Dry Type Sprinklers connected to CPVC piping, use only the following TYCO CPVC fittings:
• 1” x 1” NPT Female Adapter (P/N 80145).
• 1” x 1” x 1” NPT Sprinkler Head Adapter Tee (P/N 80249).
For dry pipe system installations, use only the side outlet of maximum 2-1/2 inch reducing tee when locating Series DS-C Dry Type Sprinklers directly below the branch line. Otherwise, use the configuration shown in Figure 6 to assure complete water drainage from above Series DS-C Dry Type Sprinklers and the branch line. Failure to do so may result in pipe freezing and water damage.
NOTICE
Do not install Series DS-C Dry Type Sprinklers into any other type fitting without first consulting the Technical Services Department. Failure to use the appropriate fitting may result in one of the following:
• failure of the sprinkler to operate properly due to formation of ice over the Inlet Plug or binding of the Inlet Plug
• insufficient engagement of the Inlet pipe-threads with consequent leakage
DrainageIn accordance with the minimum requirements of the National Fire Protection Association for dry pipe sprinkler systems, branch, cross, and feed-main piping connected to Dry Sprinklers and subject to freezing temperatures must be pitched for proper drainage.
Exposure LengthWhen using Dry Type Sprinklers in wet pipe sprinkler systems to protect areas subject to freezing temperatures, use Table A to determine a sprinkler’s appro-priate exposed barrel length to prevent water from freezing in the connecting pipes due to conduction. The exposed barrel length measurement must be taken from the face of the sprinkler fitting to the surface of the structure or insulation that is exposed to the heated area. Refer to Figure 7 for an example.
For protected area temperatures between those given above, the minimum recommended length from the face of the fitting to the outside of the protected area may be determined by interpolating between the indicated values.
Do not attempt to add additional insu-lation around the barrel in the heated area as a method to minimize conden-sation. This will reduce the calculated “Exposure Length”.
Clearance SpaceIn accordance with Section 8.4.9.2 of the 2010 edition of NFPA 13, where dry sprinklers are connected to wet pipe sprinkler systems protecting insulated freezer structures, the clearance space around the sprinkler barrel of Dry Type Sprinklers must be sealed. Due to temperature differences between two
areas, the potential for the formation of condensation in the sprinkler and subsequent ice build-up is increased. If this condensation is not controlled, ice build-up can occur that might damage the dry type sprinkler and/or prevent proper operation in a fire situation.
Use of the Model DSB-2 Dry Sprinkler Boot, described in technical data sheet TFP591 and shown in Figure 8, will provide the recommended seal.
NOTICE
For applications where a bore greater than 1-3/4 inches in diameter has been cut through the entire height of an insulated freezer ceiling creating a cavity above the sprinkler support cup (Figure 8), the cavity must not be filled.

Installation
TYCO Series DS-C Dry Concealed Pendent Sprinklers must be installed in accordance with this section.
Series DS-C Dry Type Concealed Pendent Sprinklers must only be installed in fittings that meet the requirements of the Design Criteria section. Refer to the Design Criteria section for other important require-ments regarding piping design and sealing of the clearance space around the Sprinkler Casing.
Do not install any bulb type sprinkler if the bulb is cracked or there is a loss of liquid from the bulb. With the sprinkler held horizontally, a small air bubble should be present. The diameter of the air bubble is approximately 1/16 inch (1,6 mm).
A leak-tight 1 inch NPT sprinkler joint should be obtained by applying a minimum-to-maximum torque of 20 to 30 ft. lbs. (26,8 to 40,2 Nm). Higher levels of torque may distort the sprinkler Inlet with consequent leakage or impair-ment of the sprinkler.
Do not attempt to compensate for insufficient adjustment in the Sprinkler Assembly by under or over-tightening the Sprinkler/Support Cup Assembly. Re-adjust the position of the sprinkler fitting to suit.
Step 1. Install the sprinkler in the pendent position with the centerline of the sprinkler perpendicular to the mounting surface.
Step 2. With a non-hardening pipe-thread sealant such as TEFLON pipe-thread sealant applied to the Inlet threads, hand-tighten the sprinkler into the sprinkler fitting.
Step 3. Wrench-tighten the sprinkler using either:
• a pipe wrench on the Inlet Band or the Casing (Figure 1).
• the RFII Sprinkler Wrench on the wrench flat (Figure 4).
Apply the wrench recess of the RFII Sprinkler Wrench to the wrench flat.
Note: If sprinkler removal becomes necessary, remove the sprinkler using the same wrenching method noted above. Sprinkler removal is easier when a non-hardening sealant was used and torque guidelines were followed. After removal, inspect the sprinkler for damage.
When using the RFII Sprinkler Wrench, temporarily remove the Protective Cap. Replace the Protective Cap (Figure 4) by pushing it upwards until it bottoms out against the Support Cup. The Protective Cap helps prevent damage to the Deflector and Arms during ceiling installation and/or during application of the finish coating of the
ceiling. It may also be used to locate the center of the clearance hole by gently pushing the ceiling material up against the center point of the Protective Cap.
As long as the Protective Cap remains in place, the system is considered to be “Out of Service”.
Step 4. After installing the ceiling and applying a ceiling finish, with the 2-1/2 inch (63,5 mm) diameter hole and in preparation for installing the Cover Plate 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.
Step 5. Screw on the Cover Plate/Retainer Assembly until the Retainer (Figure 2) 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 Support Cup or the Cover Plate/Retainer Assembly cannot be engaged suffi-ciently to contact the ceiling, reposition the Sprinkler Fitting.

Absence of the Cover Plate Assembly may delay sprinkler operation in a fire situation.
A Vent Hole is provided in the Bulb Seat (Figure 1) to indicate if the Dry Sprinkler is remaining dry. Evidence of leakage from the Vent Hole indicate potential leakage past the Inlet seal and the need to remove the sprinkler to determine the cause of leakage; for example, an improper installation or an ice plug. Close the fire protection system control valve and the system drain before removing the sprinkler.
When properly installed, there is a nominal 3/16 inch (4,8 mm) air gap between the lip of the Cover Plate and the ceiling, as shown in Figure 2. This air gap is necessary for proper operation of the sprinkler. If the ceiling is to be repainted after the installation of the Sprinkler, care must be exercised to ensure that the new paint does NOT seal off any of the air gap.
Do not pull the Cover Plate relative to the Enclosure. Separation may result.
Sprinklers which are found to be leaking or exhibiting visible signs of corrosion must be replaced.
Automatic sprinklers must never be painted, plated, coated, or otherwise altered after leaving the factory. Modified sprinklers must be replaced. Sprinklers that have been exposed to corrosive products of combustion, but have not operated, should be replaced if they cannot be completely cleaned by wiping the sprinkler with a cloth or by brushing it with a soft bristle brush.
Care must be exercised to avoid damage to the sprinklers - before,
during, and after installation. Sprinklers damaged by dropping, striking, wrench twist/slippage, or the like, must be replaced. Also, replace any sprinkler that has a cracked bulb or that has lost liquid from its bulb. (Ref. Installation Section.)
If a sprinkler must be removed, do not reinstall it or a replacement without reinstalling the Cover Plate Assembly. If a Cover Plate Assembly becomes dislodged during service, replace it immediately.
The owner is responsible 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. The installing contractor or sprinkler manufacturer should be contacted relative to any questions.
Automatic sprinkler systems are recom-mended to be inspected, tested, and maintained by a qualified Inspection Service in accordance with local requirements and/or national codes.
