RAPID RESPONSE Series LFII Residential Sprinklers

5.6 K-factor Horizontal Sidewall, NFPA 13 Optimized

Wet Pipe Systems

General

Description

The TYCO RAPID RESPONSE Series

LFII (TY3334) Residential Horizontal

Sidewall Sprinklers are decorative, fast response, frangible bulb sprinklers designed for use in residential occupancies such as homes, apartments, dormitories, and hotels. When enhanced flow characteristics for residential portions of any occupancy per

NFPA 13 is the major consideration, the

Series LFII (TY3334) should be the first choice.

When higher flow demands are required for residential sprinklers used in an NFPA 13 design, the large 5.6

K-factor of the Series LFII (TY3334) is an attractive choice. Although mostly intended where residential sprinklers are to be used in an NFPA 13 design, the Series LFII (TY3334) can also be used in wet pipe residential sprinkler systems for one- and two-family dwellings and mobile homes per NFPA

13D, and wet pipe residential sprinkler systems for residential occupancies up to and including four stories in height per NFPA 13R.

The recessed version of the Series

LFII (TY3334) 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 position. The adjustment provided by the Recessed

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.

Escutcheon reduces the accuracy to which the pipe nipples to the sprinklers must be cut.

The Series LFII (TY3334) has been designed with heat sensitivity and water distribution characteristics proven to help in the control of residential fires and to improve the chance for occupants to escape or be evacuated.

NOTICE

The Series LFII (TY3334) Residential Horizontal Sidewall Sprinklers described herein must be installed and maintained in compliance with this document and with the applicable standards of the National Fire Protection Association, 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 maintaining their fire protection system and devices in proper operating condition.

The installing contractor or sprinkler manufacturer should be contacted with any questions.

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 activate and flow water.

Design

Criteria

The TYCO RAPID RESPONSE Series

LFII (TY3334) 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 manufacturer’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 sprinkler 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 discharge 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/ft 2 over the “design area” comprised of the four most hydraulically demanding sprinklers for the actual coverage areas being protected by the four sprinklers.

Obstruction To Water Distribution

Sprinklers are to be located in accordance 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 TYCO Technical Data Sheet

TFP490.

Operational Sensitivity

The sprinklers are to be installed with an end-of deflector-boss to wall distance of 1-1/4 to 6 inches.

In addition the top-of-deflector-to-ceiling distance is to be within the range

(Table A) being hydraulically calculated.

Sprinkler Spacing

The minimum spacing between sprinklers is 8 feet (2,4 m) when installed with a top-of-deflector-to-ceiling distance of 4 to 6 inches (100 to 150 mm). The minimum spacing between sprinklers is 9 feet (2,7 m) when installed with a top-of-deflector-toceiling distance of 6 to 12 inches

(150 to 300 mm). The maximum spacing between sprinklers cannot exceed the width of the coverage area

(Ref. Table A) 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 (TY3334) Residential Horizontal

Sidewall Sprinkler 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 sprinkler 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 the Sprinkler by under- or over-tightening the sprinkler. Re-adjust the position of the sprinkler fitting to suit.

Series LFII Horizontal Sidewall

Sprinklers

The Series LFII Horizontal Sidewall

Sprinklers must be installed in accordance with the following instructions.

Step 1. Horizontal sidewall sprinklers are to be installed in the horizontal 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 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 reference to Figure 1, the W-Type 6 Sprinkler Wrench is to be applied to the wrench flats.

Series LFII 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 horizontal 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. 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 (Ref. Figure 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 LFII

(TY3334) 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 sprinklers are not used for hanging of any objects and that the sprinklers are only cleaned by means of gently dusting with a feather duster; otherwise, nonoperation 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 otherwise 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 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 standards of any other authorities having jurisdiction. The installing contractor or sprinkler manufacturer should be contacted relative to 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 code.
