NPT AND ISO 7-R 1 DRY-TYPE SPRINKLER ASSEMBLY FIGURE 1 SERIES DS-1, 3/4 IN. NPT, DRY-TYPE SPRINKLER ASSEMBLY Operation When the TYCO Series DS-1 Dry-Type Sprinklers, 5.6K Pendent, Upright, and Horizontal Sidewall, Quick Response (3 mm bulb) and Standard Coverage are in service, water is prevented from entering the assembly by the Plug with Sealing Assembly in the Inlet of the Sprinkler. See Figures 1 and 2. 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 Sealing Assembly from the Inlet and allowing the sprin kler to activate and flow water. Design Criteria The TYCO Series DS-1 Dry-Type Sprin- klers, 5.6K Pendent, Upright, and Hor- izontal Sidewall, Quick Response (3 mm bulb) and Standard Cover- age are intended for use in fire sprin- kler systems designed in accordance with the standard installation rules recognized by the applicable Listing or Approval agency; for example, UL Listing is based on NFPA 13 requirements. Sprinkler Fittings Install the 3/4 or 1 in. NPT Series DS-1 Dry-Type Sprinklers in the 3/4 or 1 in. NPT outlet or run of the follow- ing 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 the DS-1 Sprinklers into an elbow fittings. The Inlet of the sprinkler can contact the interior of the elbow, potentially damaging the Inlet seal. The unused outlet of the threaded tee is plugged as shown in Figure 13. You can also install the Series DS-1 Dry-Type Sprinklers in the 3/4 or 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. TFP510 Page 3 of 10 1 in.

See the Exposure Length section. For wet pipe system installations of the 1 in. NPT Series DS-1 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 wet pipe system installations of the the 3/4 in. NPT Series DS-1 Sprinklers connected to CPVC piping, use in the 3/4 in. x 3/4 in. NPT Female Adapter (P/N 80142). For dry pipe system installa- tions, use only the side outlet of maximum 2-1/2-in. reducing tee when locating the Series DS-1 Sprinklers directly below the branch line. Other- wise, use the configuration shown in Figure 13 to assure complete water drainage from above the Series DS-1 Dry-Type Sprinklers and the branch line. Failure to do so may result in pipe freezing and water damage. NOTICE Do not install the Series DS­1 Dry­Type Sprinkler 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 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.

TABLE C EXPOSED SPRINKLER BARRELS IN WET PIPE SYSTEMS MINIMUM RECOMMENDED LENGTHS meet the requirements of the Design Criteria section. See the Design Crite- ria 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 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 286°F (141°C) rating. • A leak-tight 3/4 in. NPT sprinkler joint should be obtained by applying a minimum-to-maximum torque of 10 to 20 lb-ft (13,4 to 26,8 N·m). • A leak-tight 1 in. NPT sprinkler joint should be obtained by applying a minimum-to-maximum torque of 20 to 30 lb-ft (26,8 to 40,2 N·m). Higher levels of torque can distort the sprinkler 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. Step 1. Install pendent sprinklers only in the pendent position, and install upright sprinklers only in the upright position. The deflector of a pendent or upright sprin kler must be parallel to the ceiling. Install horizontal sidewall sprinklers in the horizontal position with their cen- terline of waterway perpen dicular to the back wall and parallel to the ceiling. Ensure the word “TOP” on the De flector faces the ceiling. Step 2. With a non-hardening pipe- thread sealant such as TEFLON tape 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 (see Figures 1 and 2) • the W-Type 7 Sprinkler Wrench on the Wrench Flat (see Figure 16) Apply the Wrench Recess of the W-Type 7 Sprinkler Wrench to the Wrench Flat. 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 Figures 14 and 15, can provide the recommended seal. Installation The TYCO Series DS-1 Dry-Type Sprin- klers, 5.6K Pendent, Upright, and Hori- zontal Sidewall, Quick Response (3 mm bulb) and Standard Coverage must be installed in accordance with this section. General Instructions The Series DS-1 Dry-Type Sprinklers must only be installed in fittings that Table C 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 11 for an example. Clearance Space In accordance with NFPA 13, when connecting an area subject to freez- ing and an area containing a wet pipe sprinkler system, 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 sub- sequent ice build-up is increased. If this condensation is not controlled, ice TFP510 Page 8 of 10 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 sprinkler that has a cracked bulb or that has lost liquid from its bulb. See the Installation Section. The owner is responsible for the in spection, 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 PROTEC TION ASSOCIATION, for example, 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. Limited Warranty For warranty terms and conditions, visit www.tyco-fire.com. Note: If sprinkler removal becomes necessary, remove the sprinkler using the same wrenching method noted above. Sprinkler removal is easier when a non­hardening sealant was used and torque guidelines were followed. After removal, inspect the sprinkler for damage. Step 4. After installing the ceiling or wall and applying a ceiling finish, slide on the outer piece of the escutcheon until it comes in contact with the ceiling or wall. 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 The TYCO Series DS-1 Dry-Type Sprin- klers, 5.6K Pendent, Upright, and Hori- zontal Sidewall, Quick Response (3 mm bulb) and Standard Coverage must be maintained 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 es cutcheon, which is used to cover a clearance hole, can delay the time to sprinkler operation in a fire situation. A Vent Hole is provided in the Bulb Seat (see Figures 1 and 2) to indicate if the Dry-Type Sprinkler is remaining dry. Evi dence 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 (for example, 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.
