Product Description
Models F156-300 EC Pendent and F156-300 EC Recessed
Pendent Sprinklers are high pressure rated automatic sprin-
klers which can handle a maximum service pressure of 300
psi (20,7 bar).
The Model F156-300 EC Pendent glass bulb sprinkler com-
bines durability of a standard sprinkler 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, F2, and FP Recessed Escutcheons provide
convenient adjustment for Model F156-300 EC Sprinklers.
The two-piece construction makes field installation an easy
and rapid task. This also allows ceiling panels to later be re-
moved without shutting down the fire protection system, thus
facilitating maintenance of above ceiling services.
The Models F156-300 EC 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 and 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 increas-
es. 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 temperature rating of the sprinkler is identified by the
color of the glass bulb capsule as well as frame color where
applicable.
Application
The most common applications for Model F156-300 EC
Pendent and Recessed EC Pendent Sprinklers will be in fire
protection systems for high rise buildings or where the pres-
sure entering the sprinkler system is in excess of 175 psi (12
bar). The use of these sprinklers will provide an opportunity to
reduce or eliminate the need for pressure reducing valves.
