First Claim
Patent Images
1. A water detector comprising:
- a housing;
flow connectors carried by the housing;
at least one water presence sensor carried by the housing;
an electrically actuatable valve, carried by the housing, and having first and second states; and
control circuits, carried by the housing, coupled to the sensor and valve, and, responsive to a leakage indicating signal from the sensor, the circuits actuate the valve causing it to change state.

Abstract
A modular water leakage detector includes a housing which carries a plurality of water leakage sensors, an electrical water shutoff valve and circuitry coupled thereto. In response to sensing water leakage, the circuitry actuates the valve to shut off the water supply. Detectors can communicate alarm indicating signals directly with one another. The detectors can include a wireless transmitter and communicate with a displaced alarm monitoring system.
