Product Description
The F156 Extended Coverage Glass Bulb Sprinkler com-
bines the durability of a standard sprinkler with the attrac-
tive 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 F156 Recessed Extended Coverage glass bulb
sprinkler. Recessing the sprinkler enhances its already
low profile decorative appearance, and facilitates a rapid
and perfect installation.
Model F156 Recessed Extended Coverage escutcheon
is highly adjustable. The two piece construction makes
field installation a very easy and rapid task. This also al-
lows ceiling panels to later be removed without shutting
down the fire protection system, thus facilitating mainte-
nance of above ceiling services.
The Model F156 Extended Coverage Sprinkler utilizes
a frangible glass bulb. The glass bulb consists of an ac-
curately 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 F156 Extended Coverage Sprinkler temperature rat-
ing is identified by the color of the glass bulb capsule as
well as frame color where applicable.
