Model AV-1-300 Alarm Check Valve, 300 psi (20,7 bar)
2-1/2, 4, 6, & 8 Inch (DN65, DN100, DN150 & DN200)
Vertical or Horizontal* Installation
General
Description
The 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 protec-
tion systems. They may be installed
vertically or horizontally*, and they are
designed to automatically actuate
electric and/or hydraulic alarms when
there is a steady flow of water into the
system that is equivalent to the dis-
charge 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
monitor 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 waterway clapper.
WARNING
The Model AV-1-300 Alarm Check
Valves described herein must be in-
stalled and maintained in compliance
with this document, as well as with the
applicable standards of the National
Fire Protection Association, in addition
to the standards of any other authori-
ties having jurisdiction. Failure to do
so may impair the integrity of these
devices.
The owner is responsible for maintain-
ing their fire protection system and de-
vices in proper operating condition.
The installing contractor or manufac-
turer should be contacted relative to
any questions.
