Abstract:
A liquid or gas leak detection and control apparatus comprising:(a) a plurality of liquid or gas detectors for detecting liquid or gas;(b) a transmitter electronically associated with each liquid or gas detector in said plurality of liquid or gas detectors, said transmitter, when activated by an electronic signal by said liquid or gas detector detecting liquid or gas, transmitting audio or radio signals or electrical signals by wire to a receiver;(c) said receiver for receiving said audio or radio signals or electrical signals by wire transmitted by said transmitter and activating a control mechanism;(d) a control mechanism associated with the receiver, said control mechanism, when activated by an electronic signal from the receiver, activating a shut-off valve associated with said liquid or gas detector which controls an associated source of the liquid or gas; and(e) a power supply for electrically powering each detector, transmitter, receiver and control mechanism,wherein said plurality of liquid or gas detectors are located in separate locations in a network including a central control which electronically communicates with said plurality of liquid or gas detectors, transmitters and receivers and controls valves that regulate the sources of liquid or gas, and wherein said plurality of liquid or gas detectors are remote from said central control and said control valves are independently remotely actuable between open and closed positions in response to said communication from said central control.
