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 prole, 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 identied 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 identied 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.
