Product Description
Reliable Models F156-300 Upright, Pendent and Re-
cessed Pendent Sprinklers are high pressure rated au-
tomatic sprinklers which can handle a maximum service
pressure of 300 psi (20,7 bar).
The Model F156-300 glass bulb sprinkler combines
durability with the attractive low profile of a decorative
sprinkler. Whether installed on exposed piping or below
an office ceiling, it is functional and attractive.
The Model F1 Series Recessed Escutcheon provides
convenient adjustment for Model F156-300 Sprinklers.
The two-piece construction makes field installation an
easy and rapid task. This also allows ceiling panels to
later be removed without shutting down the fire protec-
tion system, thus facilitating maintenance of above ceil-
ing services.
The Models F156-300 Upright, Pendent and Recessed
Pendent automatic sprinklers are standard response
sprinklers which utilize a 5.0mm frangible glass bulb.
The glass bulb contains an accurately controlled amount
of special fluid hermetically sealed inside. The other
sprinkler parts are made of brass, copper or beryllium
nickel.
At normal temperatures, the glass bulb contains fluid in
both the liquid and vapor phases. 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.

Application
The most common applications for Model F156-300
sprinklers will be in fire protection systems for high rise
buildings or where the pressure entering the sprinkler
system is in excess of 175 psi (12 bar). The use of these
sprinklers will provide opportunity to reduce or eliminate
the need for pressure reducing valves.
