Abstract
A safety device for breaking power supplied to the plug of an appliance cord from a standard, preexisting electrical receptacle. The device plugs into the standard receptacle, and in turn accepts the plug of the appliance in an exposed corresponding receptacle. The device detects an audible alarm signal from a standard, preexisting smoke detector, and operates an automatic switch provided in the device. The automatic switch interrupts a power circuit which normally conducts power from the preexisting receptacle to the corresponding receptacle provided in the safety device. A control circuit operates the automatic switch responsive to detection of the audible alarm. An alarm condition indicator and manual reset are provided. The device is compact and unobtrusive, plugs manually into the preexisting receptacle, and requires no modification to the preexisting receptacle, smoke detector, or appliance in order to operate automatically. In an alternative embodiment, the device is intended for incorporation into the building wiring system, and forms a permanent component thereof.
