By spotting water in drip pans in air handler units, beneath raised floors in data centers, or on floors near sump pumps and drains, the Series WD3 Water Leak Detectors guard equipment against water damage. Once the water has risen to a point where it spans the two conductive strips on the housing's bottom, it is detected. Depending on the model selected, local notice of the alarm situation is provided by audio and visual alerts, and remote indication or control is provided by an internal switch to stop additional water buildup. The Model WD3-BP-D1-A is battery-powered for use in situations where power is not available. Alternatively, the water detector can be powered by either AC or DC supply voltages. By using the provided adjustable mounting bracket, the sensing height can be reduced to as little as 1/32". The mounting bracket can be fastened to any flat surface using either the mounting screws or the connected adhesive strips.
