Abstract
A self-contained water alarm for monitoring floor moisture comprising a plurality of pairs of sensor electrodes mounted at spaced locations on the bottom of a donut-shaped housing that can be fitted over a standpipe, the sensor electrode pairs being incorporated in feet that support the housing on a floor; the housing contains a horn or other audible alarm device, a battery, and an alarm circuit including an SCR having its main anode-cathode disclosure path connected in series with the horn and the battery and in parallel with a manual test-reset switch, and having its gate electrode connected to one sensor electrode in each pair, the other sensor electrode in each pair being connected to the battery. An auxiliary pair of sensor electrodes are connected in the circuit, in parallel with the housing-mounted sensor electrode pairs, to permit simultaneous monitoring of floor moisture and of the water level in a sump or standpipe. Provision is made for connecting a remote alarm to the device.
