Reliable Models G & F1 Open Sprinklers are similar
in design to Reliable Models G & F1 Automatic
Sprinklers except they are not equipped with fusible
or frangible element parts, and therefore, do not
operate automatically. They are installed in locations
where a blanket of water is desired over a
predetermined area. Open Sprinkler systems can be
operated manually or by quick opening valves that
are pneumatically, hydraulically or electrically
controlled.
Open Sprinklers are available in four types:
Standard Upright, Standard Pendent, Conventional.
and Sidewall.
