Technical Overview
The WD-AMX water leak detection modules are designed for use with the WD-CS, WD-PS and WD-RS water leak detection sensors.
The modules have LED Indication of the water leak status and a sounder that can be enabled or disabled. The relay output can be used in manual or
auto reset, and can be used as an alarm signal for connection to a BMS controller or remote alarm annunciation panel, such as the UI-AA-1-F.
The cable excitation used is an isolated AC signal which ensures the detector cable will not be subject to oxidation or erosion over time, avoiding the
degradation problems associated with DC systems

- Page 1 Technical Overview The WD-AMX water leak detection modules are designed for use with the WD-CS, WD-PS and WD-RS water leak detection sensors.

The relay output can be used in manual or auto reset, and can be used as an alarm signal for connection to a BMS controller or remote alarm annunciation panel, such as the UI-AA-1-F.
- Page 2 Maximum cable is 2.5mm², care must be taken not to over tighten terminals. When mounting the WD-AMX care should be taken not to stress the PCB when fitting to the DIN rail. If it is necessary to remove the module from the DIN rail, be sure to use a flat bladed screwdriver to release the DIN clips.
- Page 3 Reset: The WD-AMX will report all flood alerts by releasing the relay and activating the sounder (if enabled). Any transition will be reported for a minimum of two seconds. When the sensor stops indicating a flood, the unit resets automatically.
