Alarm check valve is a wet pipe sprinkler system water check valve, which is installed in the wet pipe sprinkler system. It is designed so that water pressure in the piping system will hold back water pressure at the valve until such time as a sprinkler is activated, hence activating the alarm.
Alarm valve includes trim packages valves, gauges, pressure switch, fittings and nipples to provide retard chamber connection, drain connections and alarm test bypass.
Retard Chamber is a valve accessory which we use for variable pressure wet systems where mechanical motor alarms or pressure switches are used. In situations where excessive water pressure surge occur the retarding chamber is needed to collect excess water from the alarm valve and feed water back into the main drain, before activating the alarm.
Water Motor Alarm is a hydraulically driven mechanical gong that automatically sounds a continuous alarm when the sprinkler system activates.
