Description
The TYCO RAPID RESPONSE Series LFII Residential Horizontal Sidewall Sprinklers (TY2334) 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 Sprinklers (TY2334) should be the first choice. The Series LFII Residential Sprinklers are intended for use in the following scenarios:
- wet pipe residential sprinkler sys - tems for one-and two-family dwell - ings and mobile homes per NFPA 13D
- wet pipe residential sprinkler sys - tems for residential occupancies up to and including four stories in height per NFPA 13R
- wet pipe sprinkler systems for the residential portions of any occu - pancy 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 in. (6,4 mm) of recessed adjustment or up to 1/2 in. (12,7 mm) of total adjustment from the flush mounting surface position. 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 has been designed with heat sensitivity and water distribution characteristics proven to help in the control of residen- tial fires and to improve the chance for occupants to escape or be evacuated. Corrosion-resistant coatings, where applicable, are utilized to extend the life of copper alloy sprinklers beyond that which would otherwise be obtained when exposed to corrosive atmo - spheres. Although corrosion-resistant coated sprinklers have passed the standard corrosion tests of the appli - cable Approval agencies, the testing is not representative of all possible cor - rosive atmospheres. Consequently, it is recommended that the end user be consulted with respect to the suit - ability of these coatings for any given corrosive environment. The effects of ambient temperature, concentration of chemicals, and gas/chemical velocity should be considered, as a minimum, along with the corrosive nature of the chemical to which the sprinklers will be exposed. NOTICE The Series LFII Residential Horizontal Sidewall Sprinklers (TY2334) 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. Sprinkler Identification Number (SIN) TY2334

Beryllium Nickel w/ TEFLON Operation 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 allowing the sprinkler to acti- vate and flow water. Design Criteria The TYCO RAPID RESPONSE Series LFII (TY2334) Residential Horizontal Sidewall Sprinklers are UL and C-UL Listed for installation in accordance with this section. 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 Type Only wet pipe systems may be utilized. Ceiling Type 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 required sprin- kler flow rate are given in Table A as a function of temperature rating and the maximum allowable coverage 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. 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 Table A 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 demand - ing sprinklers for the actual cover - age areas being protected by the four sprinklers. 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 with an end of defector-boss to wall dis - tance of 1-1/8 in. to 6 in. In addition the top-of-deflector-to- ceiling distance is to be within the range (see Table A) being hydraulically calculated. Sprinkler Spacing The minimum spacing between sprin - klers is 8 ft (2,4 m). The maximum spacing between sprinklers cannot exceed the width of the coverage area (see Table A) being hydraulically calcu- lated (for example, maximum 12 ft for a 12 ft x 12 ft coverage area, or 16 ft for a 16 ft x 20 ft coverage area). Installation The TYCO RAPID RESPONSE Series LFII (TY2334) Residential Horizontal Sidewall Sprinklers 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 in. (1,6 mm). A leak-tight 1/2 in. NPT sprinkler joint should be obtained by applying a minimum to maximum torque of 7 to 14 lb-ft (9,5 to 19,0 N∙m). 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 the sprinkler by under- or over-tightening the sprin - kler. Re-adjust the position of the sprin- kler fitting to suit. Series LFII Residential Horizontal Sidewall Sprinklers The Series LFII Horizontal Sidewall Sprinklers must be installed in accor - dance with the following instructions. Step 1. Horizontal sidewall sprinklers are to be installed in the horizontal position with their centerline of water - way perpendicular to the back wall 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 (see Fig - ure 3). With reference to Figure 1, the W-Type 6 Sprinkler Wrench is to be applied to the wrench flats. Series LFII Residential Recessed Horizontal Sidewall Sprinklers The Series LFII Recessed Horizontal Sidewall Sprinklers must be installed in accordance with the following instructions. Step A. Recessed horizontal sidewall sprinklers are to be installed in the hor- izontal position with their centerline of waterway perpendicular to the back wall and parallel to the ceiling. The word “TOP” on the Deflector is to face towards the ceiling. Step B.

7 Recessed Sprinkler Wrench (see Fig-
ure 4). With reference to Figure 1, the W-Type 7 Recessed Sprinkler Wrench is to be applied 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 Sprinkler and push the Closure over the Mounting Plate until its flange comes in contact with the wall. Care and Maintenance The TYCO RAPID RESPONSE Series LFII (TY2334) Residential Horizontal Sidewall Sprinklers 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 an Escutcheon Plate may delay the 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 sprinkler that has a cracked bulb or that has lost liquid from its bulb. See the Installation section for additional information. 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. 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.
