The water leak system comprises of a Main zone water leak panel, interface modules, sensor cable and alarm sounders. The water leak panel has potential free relay contacts which extends alarms to BMS.
The Water leak detection sensor cable typically used to detect water leaks in critical rooms to monitor leakage and optionally extend alarm in the BMS. The Cable draws excitation signal from a start of the line module. It serves as an interface between the Water leak detection panel and the Sensor Cable. The Start of Line Interface Module is locally placed in the False Flooring, and shall be connected to the WLD Panel through standard Cu- Ar Cable.
The WLD Panel is be capable of supplying power to the interface modules, and serves as the annunciation of alarms through LCD fascia. The panel activates common sounder. Testing procedure involves physical application of a wet cloth to the cable, to test the relay operation. The Panel sounds the Alarms, and optionally notifies the BMS system.
