Product Description
The Reliable Model G5-56 Dry sprinkler is a Dry Pendent

of the sprinkler assembly. The position of the sealing washer is
controlled by a fusible element at the opposite end of the sprin-

sealing washer to move out of the inlet orifice admitting water
from the supply piping. The sprinkler uses a fast-response fus-
ible element with an Ordinary, 165°F (74°C), or Intermediate,
212°F (100°C), temperature classification.
The Model G5-56 Dry sprinkler has a dropdown deflector
design that allows the sprinkler to be recessed into the ceiling
and concealed by a flat cover plate. The cover plate assembly
threads into the sprinkler' s cup and provides ½-inch (13mm) of
cover adjustment. The cover plate assembly consists of a flat
cover plate that is attached to the skirt using either 135°F (57°C)
or 165°F (74°C) temperature rated solder. The 135°F (57°C)
cover plates are for use with Ordinary temperature classifica-
tion sprinklers and the 165° (74°C) cover plates are for use with
Intermediate temperature classification sprinklers.
The Model G5-56 Dry sprinkler is available in lengths rang-
ing from 4¼ inches (108mm) to 48 inches (1219mm) in ¼-inch
(6.35mm) increments (see Fig. 1). The length of the sprinkler
must be selected to provide the Exposed Minimum Barrel
Length in a Heated Area required by Fig. 2.
The Model G5-56 Dry sprinkler is available with 1-inch NPT
or ISO 7-1 R1 threaded inlet fittings. The standard inlet fitting in-
cludes a long inlet designed to minimize the potential for water,
scale, and sediment to accumulate on the sprinkler inlet in wet-
and dry-pipe sprinkler systems. For wet-pipe sprinkler system
applications where the standard inlet interferes with installation
into existing plastic pipe fittings, an inlet fitting is available with a
short ("PL") inlet. See Fig. 3 for further information.
