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 fire fighting 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 identified 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.
