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. General Description TYCO Series DS-2 Dry-Type Sprin- klers, 11.2K Pendent, Standard (5 mm bulb) and Quick Response (3 mm bulb), and Standard Coverage are decorative glass bulb automatic sprinklers typi- cally used where: • pendent sprinklers are required on dry pipe systems that are exposed to freezing temperatures (e.g., sprin- kler drops from unheated portions of buildings) • sprinklers and/or a portion of the connecting piping may be exposed to freezing temperatures (e.g., sprin- kler drops from wet systems into freezers) NOTICE Series DS-2 Dry-Type Sprinklers described herein must be installed and maintained in compliance with this document, as well as with the applica- ble standards of the NATIONAL FIRE PROTECTION ASSOCIATION (NFPA), in addition to the standards of any other 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 con- dition.

Sprinkler Fittings Install 1 in. NPT Series DS-2 Dry-Type Sprinklers in the 1 in. NPT outlet or run of the following fittings: • malleable or ductile iron threaded tee fittings that meet the dimensional 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-2 Dry-Type 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 Figure 9. You can also install Series DS-2 Dry- Type Sprinklers in the 1 in. NPT outlet of a GRINNELL Figure 730 Mechanical Tee. However, the use of the Figure 730 Tee for this arrangement is limited to wet pipe systems. The configuration shown in Figure 8 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 10. See the Exposure Length section. For wet pipe system installations of 1 in. NPT Series DS-2 Dry-Type Sprin- klers connected to CPVC piping, use only the following TYCO CPVC fittings: • 1 in. x 1 in. NPT Female Adapter (P/N 80145) • 1 in. x 1 in. x 1 in. NPT Sprinkler Head Adapter Tee (P/N 80249) For dry pipe system installations, use only the side outlet of maximum 2 1/2 in. reducing tee when locat- ing Series DS-2 Dry-Type Sprinklers directly below the branchline. Oth- erwise, use the configuration shown in Figure 9 to assure complete water drainage from above Series DS-2 Dry- Type Sprinklers and the branchline. Failure to do so may result in pipe freezing and water damage.

TABLE B EXPOSED SPRINKLER BARRELS IN WET PIPE SYSTEMS MINIMUM RECOMMENDED LENGTHS NOTICE Do not install Series DS-2 Dry-Type Sprinkler into any other type fitting. 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 Drainage In 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 tem- peratures must be pitched for proper drainage. Clearance Space In accordance with Section 8.4.9.2 of the 2010 edition of NFPA 13, when con- necting an area subject to freezing and an area containing a wet pipe sprinkler system, the clearance space around the sprinkler barrel of dry-type sprin- klers must be sealed. Due to tempera- ture differences between two areas, the potential for the formation of conden- sation in the sprinkler and subsequent ice build-up is increased. If this con- densation 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 Sprin- kler Boot, described in Technical Data Sheet TFP591 and shown in Figure 11, can provide the recommended seal. Exposure Length When using dry sprinklers in wet pipe sprinkler systems to protect areas subject to freezing temperatures, use Table B to determine a sprinkler’s appropriate exposed barrel length to prevent water from freezing in the con- necting 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. See Figure 10 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.

General Instructions Series DS-2 Dry-Type Sprinklers must only be installed in fittings that meet the requirements of the Design Cri- teria section. See the Design Criteria section for other important require- ments regarding piping design and sealing of the clearance space around the sprinkler Casing. With reference to Figure 7, do not grasp the sprinkler by the Deflector. Failure to follow this instruction may impair performance of the device. Do not install any bulb-type sprinkler if the bulb is cracked or there is a loss of liquid from the bulb. With the sprin- kler held horizontally, a small air bubble should be present. The diameter of the air bubble is approximately 1/16 in. (1,6 mm) for the 135°F (57°C) rating to 1/8 in. (3,2 mm) for the 360°F (182°C) rating. A leak-tight 1 in. NPT sprinkler joint should be obtained by applying a min- imum-to-maximum torque of 20 to 30 lb-ft (26,8 to 40,2 N·m). Higher levels of torque may distort the sprin- kler Inlet with consequent leakage or impairment of the sprinkler. Do not attempt to compensate for insufficient adjustment in an Escutch- eon Plate by under or over-tightening the sprinkler. Re-adjust the position of the sprinkler fitting to suit. Note: Install pendent sprinklers only in the pendent position. The Deflector of a pendent sprinkler must be parallel to the ceiling. Step 1. With a non-hardening pipe- thread sealant such as TEFLON applied to the Inlet threads, hand-tighten the sprinkler into the sprinkler fitting. Do not grasp the sprinkler by the Deflec- tor, see Figure 7. Step 2. Wrench-tighten the sprinkler using either: • a pipe wrench on the Inlet Band or the Casing, see Figure 1 • the W-Type 17 Sprinkler Wrench on the Wrench Flat, see Figure 2 Apply the Wrench Recess of the W-Type 17 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. Step 3. After installing the ceiling and applying a ceiling finish, slide on the outer piece of the escutcheon until it comes in contact with the ceiling. Do not lift the ceiling panel out of its normal position. When using the Deep Escutcheon, hold the outer piece in contact with the mounting surface (ceiling or wall). Then rotate the inner piece approximately 1/4 turn with respect to the outer piece, to hold the Deep Escutcheon firmly together.

Care and Maintenance TYCO Series DS-2 Dry-Type Sprin- klers, 11.2K Pendent, Standard (5 mm bulb) and Quick Response (3 mm bulb), and Standard Coverage must be main- tained and serviced in accordance with this section. Before closing a fire protection system main control valve for maintenance work on the fire protection system that it controls, obtain permission to shut down the affected fire protection systems from the proper authorities and notify all personnel who may be affected by this action. Absence of the outer piece of an escutcheon, which is used to cover a clearance hole, may delay the time to 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 indicates potential leakage past the Inlet seal and the need to remove the sprinkler to determine the cause of leakage (e.g., an improper installation or an ice plug). Close the fire protection system control valve and drain the system before removing the sprinkler. 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 other- wise 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. Sprin- klers damaged by dropping, striking, wrench twist/slippage, or the like, must be replaced. Also, replace any sprin- kler that has a cracked bulb or that has lost liquid from its bulb, see Installation Section. 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, such as NFPA 25, in addition to the standards of any other authorities having jurisdiction. Contact the installing contractor or product manufacturer with 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.
