Product Description
Conventional (or “old-syle” 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 F1 Conventional Sprinklers are standard
response fire sprinklers utilizing a 5.0 mm glass bulb thermal
element.
Reliable Model F1FR Conventional Sprinklers are quick
response fire sprinklers utilizing a sensitive 3.0 mm thermal
glass bulb element.
These sprinklers are available in 5.6 (80 metric) and 8.0 (115

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).
