Model AV-1-300 Alarm
Check Valves are divided seat ring,
rubber-faced clapper, waterflow alarm
check valves that are intended for use
in wet pipe (automatic sprinkler) fire
protection systems. They may be in-
stalled vertically or horizontally*, and
they are designed to automatically ac-
tuate electric and/or hydraulic alarms
when there is a steady flow of wa-
ter into the system that is equivalent
to the discharge rate of one or more
sprinklers.
A separately ordered Model RC-1 Re-
tard Chamber (TFP920) is required for
installations subject to variable pres-
sures. It is used to help prevent false
alarms associated with pressure vari-
ations in public water supplies.
The AV-1-300 Alarm Check Valve Trim
includes pressure gauges to moni-
tor system pressure conditions, a by-
pass check valve, a main drain valve,
and an alarm test valve. The bypass
check valve reduces the pos sibility of
false alarms by permitting slow as well
as small transient in creases in water
supply pressure to be passed through
to the system without opening the wa-
terway clapper.
