Tyco Issue A Bedienungsanleitung

General

Description

Exposure (Outside) Protection Sprin-

klers are utilized to provide protection

from exposure fires on the outside of

buildings . The Issue A and B Window

Type Exposure Protection Sprinklers

areintendedforsprayingwateronwin-

dowglazing at prescibed spacings and

sprinkler locations at a minimum dis-

charge pressure of 7 psi (0,48 bar).

The smaller orifice Issue A Sprinklers

are normally used where exposure is

lightor moderate,theareaofcoverage

is small, or where one horizontal line

of window sprinklers is installed at

each floor. The larger orifice Issue B

Sprinklers are normally used where

exposure is severe, or where one hori-

zontal line of sprinklers is used to pro-

tect windows at more than one floor

level.

Itis recommendedthattheend userbe

consulted with respect tothe suitability

of the materials of construction and

finish for any given corrosive environ-

ment. The effects of ambient tempera-

ture, concentration of chemicals, and

gas/chemical velocity, should be con-

sidered, at a minimum, along with the

corrosive nature to which the sprin-

klers may be exposed.

The Issue A and B Window Type Ex-

posure Protection Sprinklers are a re-

designation for the Gem Issue A and

WARNINGS

The Issue A and B Window Type Ex-

posure Protection Sprinklers de-

scribed herein must be installed and

maintained in compliance with this

document, as well as with the applica-

ble standards of the National Fire Pro-

tection Association, in addition to the

standards ofany other authorities hav-

ing jurisdiction. Failure to do so may

impair the performance of these de-

vices..

The owner is responsible for maintain-

ing their fire protection system and de-

vices in proper operating condition.

The installing contractor or sprinkler

IMPORTANT

Always refer to Technical Data

Sheet TFP700 for the “INSTALLER

WARNING” that provides cautions

with respect to handling and instal-

lation of sprinkler systems and com-

ponents. Improper handling and in-

stallation can permanently damage

a sprinkler system or its compo-

nents and cause the sprinkler to fail

to operate in a fire situation. TABLE A

Criteria

Nozzle Placement. Exposure Protec-

tion Sprinkler Systems must be de-

signed, installed, and calculated in ac-

cordance with NFPA 13. Figures 2 and

3 provide nominal spray patterns.

Main Pipeline Strainers. The use of a

main pipeline strainer per NFPA 13 is

required for sprinklers having a nomi-

nal K-factor less than 2.8 (40,3).

Installation

Issue A and B Window Type Exposure

Protection Window Sprinklers must be

installed in accordance with the follow-

ing instructions:

NOTE

A leak tight 1/2 inch NPTsprinkler joint

should be obtained with a torque of 7

to 14 ft.lbs. (9,5 to 19,0 Nm). A maxi-

mum of 21 ft. lbs. (28,5 Nm) of torque

may be used to install sprinklers with

1/2 NPT connections. A leak tight 3/4

inch NPT nozzle joint should be ob-

tained with a torque of 10 to 20 ft.lbs.

(13,4 to 26,8 Nm). A maximum of 30 ft.

lbs. (40,7 Nm) of torque may be used

to install sprinklers with 3/4 NPT con-

nections. Higher levels of torque may

distort the sprinkler inlet and cause

leakage or impairment of the sprin-

klers.

Step 1. With pipe thread sealant ap-

plied to the pipe threads, hand tighten

the sprinkler into the sprinkler fitting.

Step 2. Tighten the sprinkler into the

sprinkler fitting using an adjustable

crescent wrench. With reference to

Figure 1 the adjustable crescent

wrench is to be applied to wrenchflats.

Care and

Maintenance

The Issue A and B Window Type Ex-

posure Protection Sprinklers must be

maintained and serviced in accord-

ance with the following instructions:

NOTE

Before closing a fire protection system

main control valve for maintenance

work on the fire protection system that

itcontrols,permissiontoshutdownthe

affectedfireprotectionsystemmustbe

obtained from the proper authorities

and all personnel who may be affected

by this action must be notified.

Issue A and B Window Type Exposure

Protection Sprinklers must never be

painted, plated, coated or altered in

any way after leaving the factory; oth-

erwise, the spray performance may be

impaired.

Care must be exercised to avoid dam-

age to the sprinklers - before, during,

and after installation. Sprinkler dam-

aged by dropping, striking, wrench

twist/slippage, or the like, must be re-

placed.

Frequent visual inspections are rec-

ommendedtobeinitiallyperformedfor

nozzles installed in potentially corro-

sive atmospheres to verify theintegrity

of the materials of constructionas they

may be affected by the corrosive con-

ditions present for a given installation.

Thereafter, annual inspections per

NFPA 25 are required.

Exposure protection systems for the

outside of buildings require regularly

scheduled care and maintenance by

trained personnel. In addition to in-

specting sprinklers for proper spray

performance during water flow trip

tests of the system, it isrecommended

that sprinklers be periodically in-

spected for loading/obstructions, or

other evidence of impaired protection.

The inspections should be scheduled

weekly or as frequently as may be

necessary, and corrective action must

be taken to ensure that the sprinkler

will perform as intended in the event of

a fire.

The owner is responsible for the in-

spection, testing, and maintenance of

their exposure protection system and

devices in compliance with this docu-

ment, as well as with the applicable

standards of the National Fire Protec-

tion Association (e.g., NFPA 25), in

addition to the standards of any other

authorities having jurisdiction. The in-

stalling contractor or sprinkler manu-
