Product Description
The F156, F142, F1XLH & F128 Series 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 ceil-
ing, it is functional and attractive.
Beautifully versatile is the description for the Reliable
Models F156, F142, F1XLH & F128 Series Recessed
glass bulb sprinkler. Recessing the F156, F142, F1XLH &
F128 Series enhances its already low profile decorative
appearance, and facilitates a rapid and perfect installa-
tion.
The recessed escutcheon of the Models F156, F142,
F1XLH & F128 are highly adjustable. The two piece con-
struction 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 fa-
cilitating maintenance of above ceiling services.
The F156, F142, F1XLH & F128 Series Automatic Sprin-
kler utilizes a 5.0 mm frangible glass bulb. The glass bulb
consists of an accurately controlled amount of special
fluid hermetically sealed inside 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 F156, F142, F1XLH & F128 Series Sprinkler tem-
perature rating is identified by the color of the glass bulb
capsule as well as frame color where applicable.
