The Model G5-80, G5-56, G5-42 and G5-28 are designed
for use where aesthetic appearance is important. Offices, hos-
pitals, motels and restaurants are but a few of the applications
where it can be used.
The Model G5-80, G5-56, G5-42 and G5-28 are UL Listed
Quick Response Concealed sprinklers intended for use in
accordance with NFPA 13. FM Approves the G5-56 and the
G5-28 sprinkler as a standard response concealed sprinkler
intended for use in accordance with FM Loss Prevention Data
Sheet 2.0.
The Reliable Model G5-80, G5-56, G5-42 and G5-28 uses
a proven quick response fusible element in a standard style
sprinkler frame with a drop-down deflector. This assembly is
recessed into the ceiling and concealed by a flat cover plate
assembly. The threaded engagement provides ¾” (19mm) of
cover adjustment. The flat cover plate is attached to the skirt
using either 135°F (57°C) or 165°F (74°C) ordinary tempera-
ture classification solder.
When the ceiling temperature rises, the solder holding the
flat cover plate melts, the flat cover plate released thus expos-
ing the sprinkler inside to the rising ambient temperature.
The subsequent fusing of the element opens the waterway
and causes the deflector to distribute the water. Any secure
engagement between the cover plate and cup will assure that
the drop-down deflector is properly located below the ceiling.
