Reliable F1FR-FS Series Bedienungsanleitung

Model F1FR-FS

Model F1FR-FS with optional water shield. Water shields

are used in applications where there are multiple levels of

sprinklers. The shield will prevent lower level sprinklers

from being wetted by upper level sprinklers.

Features

• Specially designed flat spray pattern

• Quick response glass bulb thermal element

• Low prole, compact design

Product Description

Reliable Model F1FR-FS Series Sprinklers are designed for

installation in accordance with CEA 4001 (Sprinkler Systems:

Planning and Installation) or EN 12845 (Fixed re ghting systems-

Automatic sprinkler systems - Design, installation and maintenance).

The flat spray pattern created by this sprinkler makes this an

excellent choice for applications with lower clearance above ceilings

and in racks.

Reliable Model F1FR-FS Series Sprinklers utilize a frangible 3.0mm

glass bulb. The glass bulb consists of an accurately controlled

amount of special fluid hermetically sealed inside of a precisely

manufactured glass capsule. This glass bulb is specially constructed

to provide fast thermal response.

At normal temperatures, the glass bulb contains the fluid in both the

liquid phase and in the vapor phase. The vapor phase can be seen

as a small bubble. As heat is applied, the liquid expands forcing

the bubble smaller and smaller as the liquid pressure increases.

Continued heating forces the liquid to push out against the bulb,

causing the glass to shatter, opening the waterway and allowing the

deflector to distribute the discharging water. The temperature rating

of Reliable Model F1FR-FS Series Sprinklers is identied by the color

of the liquid in the glass bulb thermal element in accordance with

NFPA 13.

Application

Reliable Model F1FR-FS Series Flat Spray Sprinklers are intended

for use in concealed spaces, open suspended ceilings, and in

racks in accordance with CEA 4001 (Sprinkler System Planning)

and EN 12845 (Automatic Sprinkler Systems - Design, Installation,

and Maintenance), as well as any authorities having jurisdiction

over the project.

Installation

Model F1FR-FS Series sprinklers must be installed in accordance

with CEA 4001 and EN 12845, and the requirements of all

applicable authorities having jurisdiction. Model F1FR-FS Series

sprinklers must be installed with the Reliable sprinkler installation

wrench identied in this Bulletin. Any other wrench may damage

the sprinkler.

When installed without a water shield, the Model W2 wrench

must be used. When installed with a water shield, the Model

W4 wrench must be used. The Models W2 and W4 wrenches

have two sets of jaws. Use the smallest set of jaws that t on

the wrench flats of the sprinkler. A leak tight sprinkler joint can

be obtained with a torque of 8 to 18 lb-ft (11 to 24 N.m). Do not

tighten sprinklers over the maximum recommended installation

torque. Exceeding the maximum recommended installation torque

may cause leakage or impairment of the sprinkler.

Glass bulb sprinklers have orange bulb protectors to minimize

bulb damage during shipping, handling and installation. Reliable

sprinkler installation wrenches are designed to install sprinklers

with bulb protectors in place. Remove the bulb protector at

the time when the sprinkler system is placed in service for re

protection. Removal of the bulb protector before this time may

leave the bulb vulnerable to damage. Remove bulb protectors

by undoing the clasp by hand. Do not use tools to remove bulb

protectors.

Maintenance

Reliable Model F1FR-FS Series sprinklers should be inspected

and the sprinkler system maintained in accordance with NFPA 25,

as well as the requirements of any Authorities Having Jurisdiction.

Prior to installation, sprinklers should remain in the original

cartons and packaging until used. This will minimize the potential

for damage to sprinklers that could cause improper operation or

non-operation.

Do not clean sprinklers with soap and water, ammonia liquid or

any other cleaning fluids. Remove dust by gentle vacuuming

without touching the sprinkler.

Replace any sprinkler which has been painted (other than factory

applied). A stock of spare sprinklers should be maintained to

allow quick replacement of damaged or operated sprinklers.

Failure to properly maintain sprinklers may result in inadvertent

operation or non-operation during a re event.
