Product Description
The F1FR-FS LO Flat Spray Sprinklers are designed for
installation in accordance with CEA 4001 or EN 12845
(Automatic Sprinkler Systems - Design, Installation and
Maintenance). The spray pattern created by this sprin-
kler makes this an excellent choice for applications with
lower clearance above the suspended open ceilings and
in racks.
The F1FR-FS LO Flat Spray Sprinkler utilizes a frangible
3.0mm glass bulb. The glass bulb consists of an accurate-
ly 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 deflec-
tor to distribute the discharging water.
The F1FR-FS LO Flat Spray Sprinkler temperature rating
is identified by the color of the glass bulb capsule.

Maintenance
The Model F1FR-FS LO Pendent should be inspected
quarterly. Do not clean sprinklers with soap and water, am-
monia 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 replacement 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-operation.
