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 3.0 mm 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 identified by the color of the glass
bulb capsule.
