Product Description
The F1 56 Glass Bulb Sprinkler combines the durability of
a standard sprinkler with the attractive low profile of a
decorative sprinkler. Whether installed on exposed piping
or in an office ceiling, it is functional and attractive.
Beautifully versatile is the description for the Reliable
Model F1 56 Recessed glass bulb sprinkler. Recessing the
F1 56 enhances its already low profile decorative
appearance, and facilitates a rapid and perfect installation.
Model F1 56 Recessed escutcheon is highly adjustable.
The two piece construction makes field installation a very
easy and rapid task. This also allows ceiling panels to later
be removed without shutting down the fire protection
system, thus facilitating maintenance of above ceiling
services.
The F1 56 Automatic Sprinkler utilizes a frangible 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 F1 56 Sprinkler temperature rating is identified by the
color of the glass bulb capsule as well as frame color where
applicable.
