Product Description
The F1S5-FS56, F1S5-FS42 and F1S5-FSLO Flat Spray
Sprinklers are designed for installation in accordance with
CEA 4001 or EN 12845 (Automatic Sprinkler Systems - De-
sign, Installation and Maintenance). The spray pattern cre-
ated by this sprinkler makes this an excellent choice for ap-
plications with lower clearance above the suspended open
ceilings and in racks.
The F1S5-FS56, F1S5-FS42 and F1S5-FSLO Flat Spray
Sprinklers with shield are used in applications where there
are high and lower level sprinklers. The shield is to help pre-
vent the lower level sprinklers from getting wet by the higher
level sprinklers.
The F1S5-FS56, F1S5-FS42 and F1S5-FSLO Flat Spray
Sprinkler utilize a special response frangible 5.0mm glass
bulb. The glass bulb consists of an accurately controlled
amount of special fluid hermetically sealed inside of a pre-
cisely manufactured glass capsule. This glass bulb is special-
ly constructed to provide fast thermal response.
Pendent
Pendent with shield
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 F1S5-FS56, F1S5-FS42 and F1S5-FSLO Flat Spray
Sprinkler temperature ratings are identied by the color of
the glass bulb capsule.

Installation
Models F1S5-FS56, F1S5-FS42 and F1S5-FSLO Flat Spray
Sprinklers are special response sprinklers intended for instal-
lation as specied in CEA 4001 and EN 12845. They must
also be installed with the Model D Sprinkler Wrench speci-
cally designed by Reliable for use with these sprinklers.
When installing Models F1S5-FS56, F1S5-FS42 and F1S5-
FSLO Pendent with shield use the Model GFR2 Sprinkler
Wrench. Any other type of wrench may damage these sprin-
klers.
Note: A leak tight ½” NPT sprinkler joint can be obtained
with a torque of 8-18 ft-lbs (10,8 - 24,4 N-m). Do not tight-
en sprinklers over maximum recommended torque. It may
cause leakage or impairment of the sprinklers.

Maintenance
The Models F1S5-FS56, F1S5-FS42, F1S5-FSLO Pendent,
F1S5-FS56, F1S5-FS42 and F1S5-FSLO Pendent Sprinklers
with shield should be inspected quarterly. Do not clean sprin-
klers with soap and water, ammonia or any other cleaning
fluid. Remove any sprinkler which has been painted (other
than factory applied) or damaged in any way. A stock of
spare sprinklers should be maintained to allow quick replace-
ment of damaged or operated sprinklers. Prior to installation,
sprinklers should be maintained in the original cartons and
packaging until used to minimize the potential for damage to
sprinklers that would cause improper operation or non-oper-
ation.
