Tyco\u00ae Model AV-1-300 alarm check valves are waterflow alarm check valves with a rubber-faced clapper and divided seat seal, intended for use in wet pipe (automatic sprinkler) fire protection systems. They can be installed vertically or horizontally and are designed to automatically actuate electric and\/or hydraulic alarms when there is a steady flow of water into the system equivalent to the discharge rate of one or more sprinklers. A Model RC-1 retard chamber (TFP920), ordered separately, is required for installations subject to variable pressures. It is used to help prevent false alarms associated with pressure variations in the public water supply. The AV-1-300 alarm check valve trim includes gauges to monitor system pressure conditions, a bypass check valve, a main drain valve and an alarm test valve. The bypass check valve reduces the possibility of false alarms by allowing slow, small transient increases in water supply pressure to pass through to the system without opening the waterway clapper.<\/p>\n
