Product Description
Reliable Model G Series sprinklers are standard-response
standard spray automatic sprinklers using a solder capsule
thermal element. The solder is captured in the cylinder of the
capsule by a stainless steel ball. When the solder melts, the ball
moves into the cylinder allowing the thermal element to fall away
from the sprinkler. When this occurs, the compressed strut and
lever spring free from the sprinkler. System pressure then clears
the waterway of all operating parts allowing the deflector to
evenly distribute water.
Pendent and horizontal sidewall sprinklers may be installed
exposed or surface mounted using escutcheons such as the
Reliable Models B, C, or HB (reference Technical Bulletin 204).
When installed recessed, the Model G Series sprinklers are
specifically listed with and may only be installed with listed
Reliable escutcheons. Refer to the technical information on the
following pages for specific listings for recessed installations and
Figures 6 and 7 for dimensional information.
