Product Description
The F1FR-FS56 and F1FR-FS42 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 sprinkler makes this an excellent choice for
applications with lower clearance above the suspended
open ceilings and in racks.
The F1FR-FS56 and F1FR-FS42 Flat Spray Sprinklers
with shield are used in applications where there are high
and lower level sprinklers. The shield is to help prevent the
lower level sprinklers from getting wet by the higher level
sprinklers.
The F1FR-FS56 and F1FR-FS42 Flat Spray 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 F1FR-FS56 and F1FR-FS42 Flat Spray Sprinklers
temperature rating are identied by the color of the glass
bulb capsule.
