Alarm Check Valves 300 psi 2-1/2, 4, 6, and 8 Inch
AV-1-300
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 protection 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 discharge rate of one or more sprinklers.
The Model CV-1FR Fire Protection Riser Check Valve is a compact and rugged swing-type unit that allows water flow in one direction and prevents flow in the opposite direction. A resilient elastomer seal facing on the spring loaded clapper ensures a leak tight seal and non-sticking operation. All Model CV-1FR Riser Check Valves are designed to minimize water hammer caused by flow reversal.
The Riser Manifold is approved for installation in either the horizontal or the vertical position. The optional relief
valve assembly is available for locations which require relief valves on gridded systems.
The ModelWMA-1 Water Motor Alarm is a hydraulically operated outdoor alarmdesigned for use with fire protection system waterflow detection valves. It is lightweight yet rugged, and it can be used in conjunction with alarm check, dry pipe, deluge, and preaction valves to sound a local
alarm.
The Model RC-1 Retard Chamber is required in installations that will be subject to pressure variations, as are generally associated with public water supplies in order to help prevent false alarms. The RC-1 is specifically intended for use as a separately ordered item for the Model AV-1-300 (TFP910) and AV-1-175 (TFP912) Alarm Check Valves. It can, however, also be used as a separately ordered item for changing out older style Retard Chambers used with the Central Model F/G,
Gem Model A, or Star Model E/F Alarm Check Valves.
