Product Description

The Reliable Model G5-56 Dry sprinkler is a Dry Pendent
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 fusible element at the opposite end of the
sprinkler assembly. The sprinkler is installed with the fusible
element at the ceiling of a protected space that may be sub-
ject to freezing temperatures and the inlet orifice located in a
heated area above the ceiling. Operation of the fusible ele-
ment allows the sealing washer to move out of the inlet orifice
admitting water from the supply piping. The sprinkler uses a

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 clas-
sification 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.
