Water Leak Detector - Four Zone with open/short-circuit detection
© Copyright Annicom
The AX-WLDF is a four zone water leak detection module
with open or short circuit sensor cable detection. The module
must be used with one of the AX-WLDF-C or AX-WLDF-P
range of sensor types. The AX-WLDF can have a total of
200m of cable connected to each input. Relay outputs
provide alarm signals for each individual zone, together with
a combined alarm relay. A multiplexed analogue 0-10V
output signal indicates zone status. The input sensitivity of
each zone is adjustable to ensure false returns are not given.
