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. General Description The TYCO RAPID RESPONSE Series LFII Residential Pendent and Recessed Pendent Sprinklers (TY2234) are decorative, fast response, frangible bulb sprinklers designed for use in residential occu-pancies such as homes, apart-ments, dormitories, and hotels. When aesthetics and optimized flow charac-teristics are the major consideration, the Series LFII Residential Sprinklers (TY2234) should be the first choice. The Series LFII Residential Sprinklers are intended for use in the following scenarios: • wet and dry pipe residential sprin-kler systems for one- and two-family dwellings and mobile homes per NFPA 13D • wet and dry pipe residential sprin-kler systems for residential occu-pancies 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 recessed version of the Series LFII Residential Sprinklers is intended for use in areas with finished ceilings. It employs a two-piece Style 20 Recessed Escutcheon. The Recessed Escutcheon provides 1/4 inch (6,4 mm) of recessed adjustment or up to 1/2 inch (12,7 mm) of total adjustment from the flush ceiling position. The adjustment provided by the Recessed Escutcheon reduces the accuracy to which the pipe drops to the sprinklers must be cut. The Series LFII Residential Sprinklers have been designed with heat sensi-tivity and water distribution charac-teristics proven to help in the control of residential fires and to improve the chance for occupants to escape or be evacuated. Dry Pipe System ApplicationThe Series LFII Residential Pendent and Recessed Pendent Sprinklers offers a laboratory approved option for designing dry pipe residential sprinkler systems, whereas, most residential sprinklers are laboratory 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 Pendent and Recessed Pendent Sprinklers (TY2234) 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 Residential 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 Pendent and Recessed Pendent Sprinklers (TY2234) described herein must be installed and maintained in compliance with this document and the applicable stan-dards of the National Fire Protection Association, in addition to the stan-dards of any authorities having jurisdic-tion. 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 condi-tion. Contact the installing contractor or sprinkler manufacturer with any questions.

The sprinkler flow rate is the minimum required discharge from each of the total number of “design sprinklers” as specified in NFPA 13D or NFPA 13R. 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 discharge from each of the four sprinklers is to be the greater of the following: • The flow rates given in Tables A or B as a function of temperature rating and the maximum allowable coverage area. • A minimum discharge of 0.1 gpm/ft2 over the “design area” comprised of the four most hydraulically demanding sprinklers for actual coverage areas protected by the four sprinklers. The number of “design sprinklers” specified in NFPA 13 for wet pipe systems is to be applied when designing dry pipe systems. Dry Pipe System Water DeliveryWhen using the Series LFII Residential Sprinklers (TY2234) in dry pipe sprin-kler systems, the time for water delivery must not exceed 15 seconds for the most remote operating sprinkler. Obstruction to Water DistributionSprinklers are to be located in accor-dance with the obstruction rules of NFPA 13D, 13R, and 13 as appli-cable for residential sprinklers as well as with the obstruction criteria described within the Technical Data Sheet TFP490. Operational SensitivitySprinklers are to be installed with a deflector-to-ceiling distance of 1-1/4 to 4 inches. Sprinkler SpacingThe minimum spacing between sprin-klers is 8 feet (2,4 m). The maximum spacing between sprinklers cannot exceed the length of the coverage area (Table A or B) being hydraulically calculated (e.g., maximum 12 feet for a 12 ft. x 12 ft. coverage area, or 20 feet for a 20 ft. x 20 ft. coverage area). Installation The TYCO RAPID RESPONSE Series LFII Residential Pendent and Recessed Pendent Sprinklers (TY2234) must be installed in accor-dance with this section: General InstructionsDo not install any bulb type sprin-kler if the bulb is cracked or there is a loss of liquid from the bulb. With the sprinkler held horizontally, a small air bubble should be present. The diam-eter of the air bubble is approximately 1/16 inch (1,6 mm). A leak-tight 1/2 inch NPT sprinkler joint should be obtained by applying a minimum-to-maximum torque of 7 to 14 ft.-lbs. (9,5 to 19,0 Nm). Higher levels of torque can distort the sprin-kler Inlet with consequent leakage or impairment of the sprinkler. Do not attempt to compensate for insufficient adjustment in an Escutcheon Plate by under- or over- tightening the sprinkler. Re-adjust the position of the sprinkler fitting to suit. Series LFII Residential Pendent SprinklersThe Series LFII Residential Pendent Sprinklers must be installed in accor-dance with the following instructions. Step 1. Install pendent sprinklers in the pendent position with the deflector parallel to the ceiling. Step 2. With pipe thread sealant applied to the pipe threads, hand-tighten the sprinkler into the sprinkler fitting. Step 3. Tighten the sprinkler into the sprinkler fitting using only the W-Type 6 Sprinkler Wrench (Figure 3). With reference to Figure 1, apply the W-Type 6 Sprinkler Wrench to the wrench flats. Series LFII Residential Recessed Pendent SprinklersThe Series LFII Residential Recessed Pendent Sprinklers must be installed in accordance with the following instructions. Step A. Install recessed pendent sprinklers in the pendent position with the deflector parallel to the ceiling. Step B. After installing the Style 20 Mounting Plate over the sprinkler threads and with pipe thread sealant applied to the pipe threads, hand-tighten the sprinkler into the sprinkler fitting. Step C. Tighten the sprinkler into the sprinkler fitting using only the W-Type 7 Recessed Sprinkler Wrench (Figure 4). With reference to Figure 1, apply the W-Type 7 Recessed Sprinkler Wrench to the sprinkler wrench flats. Step D. After the ceiling has been installed or the finish coat has been applied, slide on the Style 20 Closure over the Series LFII Residential Sprinkler and push the Closure over the Mounting Plate until its flange comes in contact with the ceiling.

Absence of the outer piece of an escutcheon, which is used to cover a clearance hole, can delay sprinkler operation in a fire situation. The owner must assure that the sprinklers are not used for hanging any objects and that the sprinklers are only cleaned by means of gently dusting with a feather duster; other-wise, non-operation in the event of a fire or inadvertent operation 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 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. Sprinklers 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. (Ref. Installation Section.) The owner is responsible for the inspection, testing, and mainte-nance of their fire protection system and devices in compliance with this document, as well as with the appli-cable standards of the National Fire Protection Association (e.g., 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.
