The Wet Alarm Check (WAC) valve is a clapper and wafer style check alarm valve designed to be installed in wet pipe water mist systems downstream from the system pump where the valve is fitted between two flanges. The valve is capable of detecting the small water flows which are common in the DuraQuench™ system. The valve has built in inlet and outlet pressure gauges, a drain valve, an inductive alarm sensor and Anti‐False Alarm (AFA) unit. The valve’s inductive alarm sensor provides an electrical means to detect water flow through the valve without direct contact with moving parts.
The AFA is connected to the WAC valve and monitors the inductive alarm sensor for indication of water flow. The AFA provides a factory set time delay of 8 – 10 seconds, which reduces the risk of false alarms coming from pressure shocks in the pipe system. The unit provides a relay contact that provides a means to send a signal to the alarm panel for activation of a water flow alarm bell. The unit requires 12 – 24 VDC power for operation.
The WAC valve contains sensitive components (electrical and mechanical) and should be handled with care.
