Abstract

The invention provides a monitoring system arranged to interrupt a power supply to an appliance, such as a boiler, in the event of detecting the presence of a hazardous substance, such as carbon monoxide, smoke, or natural gas. The power supply may be interrupted in response to an instantaneous measurement of a hazardous substance exceeding a threshold value. Alternatively, the power supply may be interrupted in response to a persistent presence of a hazardous substance exceeding a threshold value. In a further embodiment, the monitoring system may also be arranged to interrupt the power supply to the appliance when a service is due, and to resume power to the appliance when servicing has been carried out.
