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. Worldwide Contacts www.tyco-fire.com General Description The TYCO RAPID RESPONSE Series LFII Residential 4.9K Concealed Pendent Sprinklers (TY3596) are dec- orative, fusible solder sprinklers, avail- able in both ordinary 160°F (71°C) and intermediate 212°F (100 °C) tempera- ture rated configurations. They are designed for use in residential occu- pancies such as homes, apartments, dormitories, and hotels. The cover plate assembly conceals the sprinkler operating components above the ceiling. The flat profile of the cover plate provides the optimum aes- thetically appealing sprinkler design. In addition, the concealed design of the Series LFII Residential Con- cealed Pendent Sprinklers provides 1/2 in. (12,7 mm) vertical adjustment. This adjustment provides a measure of flexibility when cutting fixed sprin- kler drops. The Series LFII Residential Concealed Pendent Sprinklers are intended for use in the following scenarios: • Wet and dry pipe residential sprin- kler systems for one and two fam- ily dwellings and mobile homes per NFPA 13D • Wet and dry pipe residential sprin- kler systems for residential occupan- cies up to and including four stories in height per NFPA 13R • Wet and dry pipe sprinkler systems for the residential portions of any occupancy per NFPA 13 The Series LFII Residential Concealed Pendent Sprinklers have been designed with heat sensitivity and water distri- bution characteristics proven to help in the control of residential fires and to improve the chance for occupants to escape or be evacuated. The Series LFII Residential Con- cealed Pendent Sprinklers (TY3596) are shipped with a Disposable Protec- tive Cap. The Protective Cap is tem- porarily removed for installation, and then it can be replaced to help protect the sprinkler while the ceiling is being installed or finished. The tip of the Pro- tective Cap can also be used to mark the center of the ceiling hole into the plaster board, ceiling tiles, and so on, by gently pushing the ceiling product against the Protective Cap. When the ceiling installation is complete the Pro- tective Cap is removed and the Cover Plate Assembly is installed. Dry Pipe System Application The 160 °F (71°C) temperature rated Series LFII Residential Concealed Pendent Sprinklers offer a laboratory approved option for designing dry pipe residential sprinkler systems, whereas, most residential sprinklers are labora- tory approved for wet systems only. Through extensive testing, it has been determined that the number of design sprinklers (hydraulic design area) for the Series LFII Residential Concealed Pendent Sprinklers need not be increased over the number of design sprinklers (hydraulic design area) as specified for wet pipe sprinkler systems, as is accustomed for density/ area sprinkler systems designed per NFPA 13. Consequently, the Series LFII Residen- tial Concealed Pendent Sprinklers offer the features of non-water filled pipe in addition to not having to increase the number of design sprinklers (hydraulic design area) for systems designed to NFPA 13, 13D, or 13R. NOTICE The Series LFII Residential Concealed Pendent Sprinklers (TY3596) described herein must be installed and main- tained in compliance with this docu- ment and with the applicable standards of the NATIONAL FIRE PROTECTION ASSOCIATION (NFPA), 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 con- dition. Contact the installing contrac- tor or product manufacturer with any questions.

Operation 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 Arms drops down to its operated position. The fusible link of the sprin- kler assembly is comprised of two link halves that are soldered together with a thin layer of solder. When the rated temperature is reached, the solder melts and the two link-halves separate allowing the sprinkler to activate and flow water.

TABLE A WET PIPE SYSTEM SERIES LFII RESIDENTIAL 4.9 K-FACTOR FLAT PLATE CONCEALED PENDENT SPRINKLER (TY3596) NFPA 13D, 13R, AND 13 HYDRAULIC DESIGN CRITERIA TABLE B DRY PIPE SYSTEM RAPID RESPONSE SERIES LFII RESIDENTIAL 4.9 K-FACTOR FLAT PLATE CONCEALED PENDENT (TY3596) NFPA 13D, 13R, AND 13 HYDRAULIC DESIGN CRITERIA TFP442 Page 4 of 6 The number of “design sprinklers” specified in NFPA 13D and 13R for wet pipe systems is to be applied when designing dry pipe systems. Hydraulic Design (NFPA 13) For systems designed to NFPA 13, the number of design sprinklers is to be the four most hydraulically demanding sprinklers. The minimum required dis- charge from each of the four sprinklers is to be the greater of the following: • The flow rates given in Tables A and B as a function of temperature rating and the maximum allowable cover- age area • A minimum discharge of 0.1 GPM/ft2 over the design area comprised of the four most hydrauli- cally demanding sprinklers for actual coverage areas protected by the four sprinklers The number of design sprinklers speci- fied in NFPA 13 for wet pipe systems is to be applied when designing dry pipe systems. Dry Pipe System Water Delivery When using the Series LFII Residen- tial Concealed Pendent Sprinklers in dry pipe sprinkler systems, the time for water delivery must not exceed 15 seconds for the most remote operat- ing sprinkler. Obstruction to Water Distribution Sprinklers are to be located in accor- dance with the obstruction rules of NFPA 13D, 13R, and 13 as applicable for residential sprinklers as well as with the obstruction criteria described within the Technical Data Sheet TFP490. Operational Sensitivity The sprinklers are to be installed rela- tive to the ceiling mounting surface as shown in Figure 2. Sprinkler Spacing The minimum spacing between sprin- klers is 8 ft (2,4 m). The maximum spacing between sprinklers cannot exceed the length of the coverage area (see Table A or B) being hydraulically calculated, for example, maximum 12 ft for a 12 ft x 12 ft coverage area, or 20 ft for a 20 ft x 20 ft coverage area. The Series LFII must not be used in applications where the air pres- sure above the ceiling is greater than that below. Down drafts through the Support Cup could delay sprinkler operation in a fire situation. Installation The TYCO RAPID RESPONSE Series LFII Residential Concealed Pendent Sprinklers (TY3596) must be installed in accordance with this section. General Instructions Damage to the fusible Link Assembly during installation can be avoided by handling the sprinkler by the support cup only. Therefore, do not apply pres- sure to the fusible Link Assembly. A 1/2 in. NPT sprinkler joint should be obtained with a minimum to maximum torque of 7 to 14 lb-ft (9,5 to 19,0 N·m). Higher levels of torque may distort the sprinkler inlet with consequent leakage or impairment of the sprinkler. Do not attempt to compensate for insufficient adjustment in the Cover Plate Assembly by under-or over- tightening the Sprinkler. Readjust the position of the sprinkler fitting to suit. Step 1. The sprinkler must only be installed in the pendent position and with the centerline of the sprinkler per- pendicular to the mounting surface. Step 2. Remove the Protective Cap. Step 3. With pipe thread sealant applied to the pipe threads, and using the W-Type 18 Wrench shown in Figure 3, install and tighten the Sprinkler/ Support Cup Assembly into the fitting. The W-Type 18 Wrench will accept a 1/2 in. ratchet drive. Step 4. Replace the Protective Cap by pushing it upwards until it bottoms out against the Support Cup. The Protec- tive Cap helps prevent damage to the Deflector and Guide Pins 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 against the center point of the Cap. 1/2" NPT 3-3/16" DIA. (81,0 mm) 2-1/2" DIA.

After the ceiling has been com- pleted with the 2-1/2 in. (63 mm) diam- eter clearance 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 6. Push on the Cover Plate Assembly until its flange comes in contact with the ceiling. Do not continue to push on the Cover Plate Assembly such that it lifts a ceiling panel out of its normal position. If the Cover Plate Assembly cannot be engaged with the Mounting Cup or the Cover Plate Assembly cannot be engaged sufficiently to contact the ceiling, the Sprinkler Fitting must be repositioned. Care and Maintenance The TYCO RAPID RESPONSE Series LFII Residential Concealed Pendent Sprinklers (TY3596) 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 which it controls, permission to shut down the affected fire protection system must be obtained from the proper authorities and all personnel who may be affected by this action must be notified. Absence of a Cover Plate may delay the sprinkler operation in a fire situation. When properly installed, there is an air gap between the lip of the Cover Plate and the ceiling. The Ordinary Tem- perature Cover Plate assembly has a nominal 1/8 in. (3,2 mm) air gap. The Intermediate Temperature Cover Plate has a nominal 3/32 (2,4 mm) air gap, as shown in Figure 2. This air gap is necessary for proper operation of the sprinkler by allowing heat flow from a fire to pass below and above the Cover Plate to help assure appropriate release of the Cover Plate in a fire situation. 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. Factory painted Cover Plates must not be repainted. They should be re placed, if necessary, by factory painted units. Non-factory applied paint may adversely delay or prevent sprinkler operation in the event of a fire. 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. Modi- fied or over heated sprinklers must be replaced. Care must be exercised to avoid damage before, during, and after instal- lation. Sprinklers damaged by drop- ping, striking, wrench twist/slippage, or the like, must be replaced. 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. Contact the installing contractor or product manufacturer with any questions. The owner must assure that the sprin- klers are not used for hanging any objects and that the sprinklers are only cleaned by means of gently dusting with a feather duster; otherwise, non- operation in the event of a fire or inad- vertent operation may result. Automatic sprinkler systems should be inspected, tested, and maintained by a qualified Inspection Service in accor- dance with local requirements and/or national codes.
