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 Horizontal Sidewall Sprinklers (TY1334) are decorative, fast response, frangible bulb sprinklers designed for use in residential occu- pancies such as homes, apartments, dormitories, and hotels. When aesthet- ics and optimized flow characteristics are the major consideration, the Series LFII Residential Sidewall Sprinklers (TY1334) should be the first choice. The Series LFII Residential Sprinklers are intended for use in the following scenarios: • wet and dry pipe residential sprinkler systems for one- and two- family dwellings and mobile homes per NFPA 13D • wet and dry pipe residential sprinkler systems for residential occupancies 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 walls. 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 mounting surface posi- tion. The adjustment provided by the Recessed Escutcheon reduces the accuracy to which the pipe nipples 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 Application The Series LFII Residential Horizon- tal and Recessed Horizontal Sidewall Sprinklers offers a laboratory approved option for designing dry pipe residen- tial 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 Horizon- tal Sidewall Sprinklers (TY1334) 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 Resi- dential 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. Non-water filled pipe will permit options for areas sensitive to freezing. NOTICE The Series LFII Residential Horizontal Sidewall Sprinklers described herein must be installed and maintained in compliance with this document and the applicable standards of the National Fire Protection Association, in addi- tion to the standards of any 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. The installing contractor or sprinkler manufacturer should be contacted with any questions.

When the rated temperature is reached, the fluid expands sufficiently to shatter the glass bulb, allowing the sprinkler to activate and flow water. Design Criteria The TYCO RAPID RESPONSE Series LFII Residential Horizontal and Recessed Horizontal Sidewall Sprin- klers (TY1334) are UL and C-UL Listed for installation in accordance with the following criteria. Residential Sprinkler Design Guide When conditions exist that are outside the scope of the provided criteria, refer to the Residential Sprinkler Design Guide TFP490 for the manufactur- er’s recommendations that may be acceptable to the local authority having jurisdiction. System Types Per the UL Listing, wet pipe and dry pipe systems may be utilized. Per the C-UL Listing, only wet pipe systems may be utilized. Refer to Technical Data Sheet TFP485 about the use of Residential Sprinklers in residential dry pipe systems. Ceiling Types Smooth flat horizontal, or beamed, or sloped, in accordance with the 2013 Edition of NFPA 13D, 13R, or 13 as applicable. Hydraulic Design (NFPA 13D and 13R) For systems designed to NFPA 13D or NFPA 13R, the minimum re quired sprinkler flow rates are given in Tables A and B as a function of temperature rating and the maximum allowable cov- erage areas. 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 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 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 design- ing dry pipe systems. Dry Pipe System Water Delivery When using the Series LFII Residential Horizontal Sidewall Sprinklers (TY1334) 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 applica- ble for residential sprinklers as well as with the obstruction criteria described within the TYCO Technical Data Sheet TFP490. Operational Sensitivity The sprinklers are to be installed with an end-of-deflector-boss to wall dis- tance of 1-1/4 to 6 inches. In addition the top-of-deflector-to-ceil- ing distance is to be within the range (Tables A and B) being hydraulically calculated. Sprinkler Spacing The minimum spacing between sprin- klers is 8 feet (2,4 m). The maximum spacing between sprinklers cannot exceed the width of the coverage area (Tables A and B) being hydraulically calculated (e.g., maximum 12 feet for a 12 ft. x 12 ft. coverage area, or 16 feet for a 16 ft. x 20 ft. coverage area.). Installation The TYCO RAPID RESPONSE Series LFII Residential Horizontal and Recessed Horizontal Sidewall Sprin- klers (TY1334) must be installed in accordance with this section. General Instructions 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 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 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. Series LFII Residential Horizontal Sidewall Sprinklers The Series LFII Residential Horizontal Sidewall Sprinklers must be installed in accordance with the following instructions. Step 1. Install horizontal sidewall sprin- klers in the horizontal position with their centerline of waterway perpendicular to the backwall and parallel to the ceiling. The word “TOP” on the Deflector is to face towards the ceiling with the front edge of 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 ref- erence to Figure 1, apply the W-Type 6 Sprinkler Wrench to the wrench flats. Series LFII Residential Recessed Horizontal Sidewall Sprinklers The Series LFII Residential Recessed Horizontal Sidewall Sprinklers must be installed in accordance with the follow- ing instructions. Step A. Install recessed horizontal sidewall sprinklers in the horizontal position with their centerline of water- way perpendicular to the backwall and parallel to the ceiling. The word “TOP” on the Deflector is to face towards 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 wall has been installed or the finish coat has been applied, slide on the Style 20 Closure over the Series LFII Residential Sprin- kler and push the Closure over the Mounting Plate until its flange comes in contact with the wall. TFP410 Page 4 of 6 Care and Maintenance The TYCO RAPID RESPONSE Series LFII Residential Horizontal and Recessed Horizontal Sidewall Sprin- klers (TY1334) 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 escutcheon, which is used to cover a clearance hole, can delay sprinkler operation in a fire situation. 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. 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. Sprin- klers damaged by dropping, striking, wrench twist/slippage, or the like, must be replaced. Also, replace any sprin- kler that has a cracked bulb or that has lost liquid from its bulb. (Ref. Installa- tion Section.) 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 (e.g., NFPA 25), in addition to the stan- dards of any authorities having jurisdic- tion. Contact the installing contractor or sprinkler manufacturer regarding 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. Max.
