(Refer to Figure 1.) They are suppression-mode sprinklers that are especially advantageous as a means of eliminating the use of in-rack sprinklers when protecting high-piled storage. The Model ESFR-25 is typically used for the following commodities and storage arrangements: Most encapsulated or non-encapsulated common materials including cartoned, unexpanded plastics Uncartoned (exposed) expanded plastics in accordance with NFPA 13 and FM Global standards Some storage arrangements of rubber tires, roll paper, flammable liquids, aerosols, and automotive components For specific criteria, refer to the tables in this data sheet as well as the applicable design standard. The ESFR-25 provides the system designer with hydraulic and sprinkler placement options not presently available to the traditional ESFR sprinklers having a nominal K-factor of 14.0. In particular, the Model ESFR-25 has been designed to IMPORTANT Always refer to Technical Data Sheet TFP700 for the INSTALLER WARNING that provides cautions with respect to handling and installation of sprinkler systems and components. Improper handling and installation can permanently damage a sprinkler system or its components and cause the sprinkler to fail to operate in a fire situation or cause it to operate prematurely. operate at substantially lower-end head pressures, as compared to ESFR sprinklers having a nominal K-factor of 14.0. This feature offers flexibility when sizing system piping, as well as possibly reducing or eliminating the need for a system fire pump. Also, the Model ESFR-25 permits use of a maximum deflector-to-ceiling distance of 18 inches (460 mm) versus 14 inches (360 mm). Additionally, a storage arrangement of 40 ft. (12,2 m) with a ceiling height of 45 ft. (13,7 m) does not require in-rack sprinklers as do other ESFR sprinklers having a nominal K-factor of 14.0. Applications for the Tyco ESFR Sprinklers are expanding beyond currently recognized installation standards. For information on research fire tests (with flammable liquids and aerosols, for example) that may be acceptable to an Authority Having Jurisdiction, contact the Technical Services department. NOTICE The Model ESFR-25 Sprinklers described herein must be installed and maintained in compliance with this document, as well as with the applicable standards of the National Fire Protection Association, in addition to the standards of any authorities having jurisdiction (for example, FM Global). 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 installing contractor or sprinkler manufacturer should be contacted with any questions. In all cases, the appropriate NFPA or FM installation standard must be referenced to ensure applicability and to obtain complete installation guidelines. The general guidelines in this data sheet are not intended to provide complete installation criteria.

Installation The Tyco Model ESFR-25 Pendent Sprinklers are to be installed in accordance with the following instructions. NOTICE Damage to the fusible Link Assembly during installation can be avoided by handling the sprinkler by the frame arms only (that is, do not apply pressure to the fusible Link Assembly), and by using the appropriate sprinkler wrench. Failure to do so can lead to an unstable link assembly and premature activation of the sprinkler. Damaged sprinklers must be replaced. Obtain a leak-tight 1-inch NPT sprinkler joint by applying a minimum-tomaximum torque of 20 to 30 ft.lbs. (26,8 to 40,2 Nm). Higher levels of torque can distort the sprinkler Inlet with consequent leakage or impairment of the sprinkler. Step 1. Install the ESFR-25 Pendent Sprinkler in the pendent position. Step 2. With pipe-thread sealant applied, hand-tighten the sprinkler into the sprinkler fitting. Do not apply pressure to the Link Assembly, and handle the ESFR-25 Sprinkler only by the Frame arms. Step 3. Wrench-tighten the ESFR- 25 Sprinkler using only the W-Type 1 Sprinkler Wrench (Figure 2) and by fully engaging (seating) the wrench on the sprinkler wrench flats. Step 4. After installation, inspect the Link Assembly of each ESFR-25 Sprinkler for damage. In particular, verify that the Link Assembly and Hook are positioned as illustrated in Figure 1, and that the Link Assembly has not been bent, creased, or forced out of its normal position in any way. Replace damaged sprinklers. WRENCH RECESS "FITTING SIDE" TOWARDS SPRINKLER FITTING FIGURE 2 W-TYPE 1 SPRINKLER WRENCH

Replace sprinklers that: were modified or over-heated. were damaged by dropping, striking, wrench twisting, wrench slippage, or the like. are leaking or exhibiting visible signs of corrosion. Responsibility lies with the owner 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 authorities having jurisdiction. Contact the installing contractor or sprinkler manufacturer regarding any questions. Automatic sprinkler systems are recommended to be inspected, tested, and maintained by a qualified Inspection Service in accordance with local requirements and/or national codes.
