Product Description
Conventional (or “old-style” sprinklers) direct approximately 40%
of their water discharge up against the ceiling and the remainder
downward to the floor, and may be used in either the upright or
pendent position.
Reliable Model G Conventional Sprinklers are standard-response
fire sprinklers utilizing a solder capsule/strut and lever thermal
element.
These sprinklers are available in 4.10 (59.1 metric), 5.62 (81.0
metric), and 8.2 (118.2 metric) K factor.
When used in the pendent position, sprinklers may be installed
exposed or surface mounted using escutcheons such as the
Reliable Models B, C, or HB (reference Technical Bulletin 204).
Table A provides a summary of the approvals and availability of
specific Model G Series Conventional sprinkler configurations.
