A method is disclosed for detecting a condition indicative of fire or elevated potential for fire, broadcasting a signal in response to its detection and for operating various controlling devices in response to the broadcast signal in order to enable or disable valves or appliances connected to a power supply through the controllers. Also disclosed is a system having a sensor, a transmitter responsive to the sensor, a receiver for receiving signals from the transmitter and controllers responsive to a signal from the receiver for controlling devices in accordance with the method of the invention. Each of the controllers is shifted from its normal position to a second position upon the receipt of a signal from any one of the sensors, and more than one controller device may be controlled by a given receiver. Multiple sensors, each capable of detecting a different condition, indicative of fire or elevated potential for fire such as the presence of smoke or strong vibration, can be used in a single system for activating all the controller devices upon the detection of a condition indicative of fire or elevated potential for fire.
