Product Description

Reliable Model F1FR series sprinklers are quick-response

standard spray automatic re sprinklers utilizing a sensitive 3.0 mm

glass bulb thermal element.

Pendent and horizontal sidewall sprinklers may be installed

exposed or surface mounted using escutcheons such as the

Reliable Models B, C, or HB (reference Technical Bulletin 204).

When installed recessed, the Model F1FR42 series sprinklers

are specically listed with and may only be installed with listed

Reliable escutcheons. Refer to the technical information on the

following pages for specic listings for recessed installations and

refer to Figure 3 for dimensional information.

When tted with an approved water shield, these sprinklers may

considered intermediate sprinklers for use in racks, below grated

walkways, and other areas where intermediate level sprinklers are

required.

Table A provides a summary of the approvals and availability of

specic Model F1FR series sprinkler congurations. Additional

technical information for each sprinkler model is provided on the

following pages.

Note: This bulletin may contain information on New and Legacy

sprinklers that reflects a dimensional change only. Sprinkler

Identication Number (SIN), application, performance, and

listings/approval are not otherwise affected. Sprinklers with new

frames can be identied by a rotoclip indent on one side of the

wrench boss and in some cases an installed rotoclip. Sprinklers

Installation

Model F1FR Series sprinklers must be installed in accordance with

NFPA13 and the requirements of all applicable authorities having

jurisdiction. Model F1FR Series sprinklers must be installed with

the Reliable sprinkler installation wrench identied in this Bulletin.

Any other wrench may damage the sprinkler. A leak tight sprinkler

joint can be obtained with a torque of 6 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 or protective

caps 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.

Finishes(1) Table B

Maintenance

Reliable Model F1FR 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.
