ABSTRACT:
A gas monitoring system for a kitchen environment in a house and the like which is supplied with gas from a pressurized gas container or from a public gas supply to sense a possibly occurring gas leak. The system comprises a valve controlling the flow of gas from the container to a cooking range. Leaked gas is detected by a sensor which activates a visual and an audible alarm circuit and which operates a valve to terminate gas flow. The electronic alarm circuit is an integrated circuit, so that it can be located in a small hermetically sealed container, together with the power supply. The alarms stay on even after the gas leaked has been removed, until the system is reset by a manual switch. A manual override is provided to allow gas flow in the event of power failure or system failure in areas where service may be delayed.
