Product Description
The Reliable Model G5-56 300 Concealer
quick response fusible element in a standard style sprin-
kler frame with a drop-down deflector. This assembly is re-
cessed into the ceiling and concealed by a flat cover plate
assembly. This threaded engagement provides ¾" (19mm)
of cover adjustment. The flat cover plate is attached to the
skirt using 135°F (57°C) ordinary temperature classification
solder or 165°F (74°C) intermediate temperature classifica-
tion solder. When the ceiling temperature rises, the solder
holding the flat cover plate melts, the flat cover plate re-
leased thus exposing the sprinkler inside to the rising ambi-
ent temperature.
The subsequent fusing of the solder element in the sprin-
kler opens the waterway and causes the deflector to drop
into position to distribute the discharging water. Any secure
engagement between the cover plate and cup will assure
that the drop-down deflector is properly located below the
ceiling.
