General Description TYCO RAPID RESPONSE Series LFII Residential 4.9K Pendent and Recessed Pendent Sprinklers (TY2234) are decorative, fast response, frangi-ble bulb sprinklers designed for use in residential occupancies such as homes, apartments, dormitories, and hotels. When aesthetics and optimized flow characteristics are the major con-sideration, 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-fam-ily 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 ceilings.

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 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.

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.

Dry Pipe System Application The Series LFII Residential Pendent and Recessed Pendent Sprinklers offers a laboratory approved option for designing dry pipe residential sprin-kler 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 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.

NOTICE

The Series LFII Residential Pendent and Recessed Pendent Sprinklers (TY2234) described herein must be installed and maintained in compli-ance with this document and the appli-cable 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.

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 tem-perature 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.

The number of design sprinklers speci-fied in NFPA 13D and 13R for wet pipe systems is to be applied when design-ing 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 Table 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 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 Residential Sprinklers (TY2234) in dry pipe sprin-kler systems, the time for water deliv-ery must not exceed 15 seconds for the most remote operating 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.

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 (Table A or B) being hydraulically calcu-lated, 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.

Installation TYCO RAPID RESPONSE Series LFII Residential 4.9K Pendent and Recessed Pendent 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 min-imum-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 an Escutch-eon Plate by under- or over- tightening the sprinkler. Re-adjust the position of the sprinkler fitting to suit.

Pendent Sprinklers The 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 par-allel 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.

Recessed Pendent Sprinklers The Series LFII Residential Recessed Pendent Sprinklers must be installed in accordance with the following instructions:

Step A. Install recessed pendent sprin-klers 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 Sprin-kler and push the Closure over the Mounting Plate until its flange comes in contact with the ceiling.

Care and Maintenance TYCO RAPID RESPONSE Series LFII Residential 4.9K Pendent and Recessed Pendent 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 that it controls, permission to shut down the affected fire protection system must be obtained 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 sprinkler that has a cracked bulb or that has lost liquid from its bulb. See the 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, for example, NFPA 25, in addition to the standards of any 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.
