Product Description
The Reliable Model F3Res44 Dry sprinkler is a Dry Horizontal
Sidewall sprinkler, where the sealing washer is located at
the inlet end of the sprinkler assembly. The position of the
sealing washer is controlled by a fluid-filled glass bulb thermal
element at the opposite end of the sprinkler assembly. The
sprinkler is installed with the thermal element in a protected
space that may be subject to freezing temperatures and the
inlet orifice located in a heated area that is separated from
the protected space. Operation of thermal element allows
the sealing washer to move out of the inlet orifice admitting
water from the supply piping. The sprinkler uses a fast-
response thermal element with an Ordinary, 155°F (69°C), or
Intermediate, 175°F (79°C), temperature classification.

mount installation (standard escutcheon), recessed installa-
tion (F2 escutcheon) and extended installation (HB escutch-
eon). The standard escutcheon includes up to 1-1/2-inch (38
