Product Description
Reliable Models F1-300 Upright, Pendent and 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 F1-300 glass bulb sprinkler combines dura-
bility with the attractive low profile of a decorative sprinkler.
Whether installed on exposed piping or below an office ceil-
ing, 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 Pen-
dent 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 liq-
uid 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 distrib-
ute the discharging water.

Application
The most common applications for Model F1-300 sprin-
klers will be in fire protection systems for high rise build-
ings or where the pressure entering the sprinkler system
is in excess of 175 psi (12 bar). The use of these sprin-
klers will provide opportunity to reduce or eliminate the
need for pressure reducing valves.
