Product Description
The F156 Series Glass Bulb Sprinkler combines the
durability of a standard sprinkler with the attractive low
profile of a decorative sprinkler. Whether installed on ex-
posed piping or in an office ceiling, it is functional and
attractive.
Beautifully versatile is the description for the Reliable
Model F156 Series Recessed glass bulb sprinkler. Re-
cessing the F156 Series enhances its already low profile
decorative appearance, and facilitates a rapid and per-
fect installation.
Model F156 Series Recessed escutcheon is highly ad-
justable. The two piece construction makes field installa-
tion 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 F156 Series Automatic Sprinkler utilizes a 5.0 mm
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 deflector to distribute the discharging wa-
ter.
The F156 Series Sprinkler temperature rating is identi-
fied by the color of the glass bulb capsule as well as
frame color where applicable
