Model F1-300
300 psi (20,7 bar) Rated
Standard Response
Sprinklers
Product Description
Reliable Models F1-300 Upright, Pendent and
Recessed Pendent Sprinklers are high pressure rated
automatic sprinklers which can handle a maximum
service pressure of 300 psi (20,7 bar).
The Model F1-300 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 Recessed Escutcheon provides
convenient adjustment for Model F1-300 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 protection
system, thus facilitating maintenance of above ceiling
services.
The Models F1-300 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.
The temperature rating of the sprinkler is identified by
the color of the glass bulb.
Application
The most common applications for Model F1-300
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.
