PDF Content Summary: Worldwide Contacts tyco-fire.com Series DS-1 Dry-Type Sprinklers 5.6K Horizontal Sidewall Standard and Quick Response, Extended Coverage

General Description TYCO Series DS-1 Dry-Type Sprinklers, 5.6 K-factor Horizontal Sidewall, Stan dard (5 mm Bulb) and Quick Response (3 mm Bulb) and Extended Cover age, are decorative glass bulb auto matic sprinklers typically used where the sprinklers and/or a portion of the connecting piping may be exposed to freezing temperatures; for example, horizontal piping extensions through a wall to protect an unheated area of a building. Series DS-1 Dry-Type Sprin klers are designed for extended cover age use in light hazard occupancies. NOTICE Series DS-1 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 maintain ing their fire protection system and devices in proper operating condition. Contact the installing contractor or product manufacturer with any ques tions. Series DS-1 Dry-Type Sprinklers must only be installed in fittings that meet the requirements of the Design Criteria section. IMPORTANT Refer to Technical Data Sheet TFP2300 for warnings pertaining to regulatory and health information. Always refer to Technical Data Sheet TFP700 for the “INSTALLER WARNING” that provides cautions with respect to handling and instal lation of sprinkler systems and com ponents. Improper handling and installation can permanently damage a sprinkler system or its compo nents and cause the sprinkler to fail to operate in a fire situation or cause it to operate prematurely.

Figure 1) in the Inlet of the sprinkler. 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 and Gasketed Spring Plate Seal from the Inlet allowing the sprinkler to activate and flow water.

Design Criteria TYCO Series DS-1 Dry-Type Sprin klers 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 1 inch NPT Series DS-1 Dry-Type 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-1 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 5. You can also install Series DS-1 Dry Type Sprinklers in the outlet. The configuration shown in Figure 6 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 6. Refer to the Exposure Length section. For wet pipe system installations of 1 inch 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 dry pipe system installations, use only the side outlet of maximum 2-1/2 in. reducing tee when locating Series DS-1 Dry-Type Sprinklers directly below the branch line. Otherwise, use the configuration shown in Figure 4 to assure complete water drainage from above 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 Series DS-1 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 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 HOLE ADHESIVE DSB-2 BOOT STRAP TIES (ENDS ON OPPOSING SIDES OF BOOT) INSULATED FREEZER STRUCTURE DS-1 SHOWN WITH STANDARD ESCUTCHEON sprinkler systems to protect areas subject to freezing temperatures, use 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. Refer to Figure 6 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. 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 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 7, can provide the recommended seal.
