Product Description
F1FR56-300 Upright, Pendent, Recessed Pendent,
and Concealed Pendent
Reliable Models F1FR56–300 QR Upright, Pendent and
Recessed Pendent Sprinklers are high pressure rated au-
tomatic sprinklers which can handle a maximum service
pressure of 300 psi (20,7 bar).
The Reliable Model F1FR56-300/CCP Quick Response
Concealed Sprinkler is an attractive, low profile concealed
sprinkler assembly. This sprinkler assembly utilizes a
Model F1FR56-300 pendent sprinkler in a Model CCP
cup and cover plate assembly. The cup is securely fac-
tory threaded on the sprinkler inlet end. The assembly is
shipped with a protective cap. The sprinkler and cup are
easily installed into the drop nipple using the Model GFR2
Sprinkler Wrench. The cover plate assembly is attached to
the sprinkler cup using a cover plate assembly with flex-
ible tabs for threaded engagement. Simply push on the
cover plate, then turn to adjust or remove the cover plate
assembly.
The cover plate is attached to the skirt using 135°F
(57°C) or 165°F (74°C) ordinary temperature classifica-
tion solder. When the ceiling temperature rises, the solder
holding the cover plate melts, allowing the release of this
part and thus exposing the Model F1FR56-300 sprinkler
inside to the rising ambient temperature.

These automatic sprinklers are quick response sprin-
klers which utilize a 3.0mm frangible glass bulb. They
have demonstrated response times in laboratory tests
which are five to ten times faster than standard response
sprinklers. This quick response enables Model F1FR56-
300 sprinklers to apply water to a fire much faster than
standard response sprinklers of the same temperature rat-
ing.
The glass bulb contains an accurately controlled amount
of special fluid hermetically sealed inside. The other sprin-
kler 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.
