Patent ID: 7817048

Claim:
A system for detecting a fire at an electric cook-stove and for interrupting the supply of electricity to burners of the electric cook-stove upon the occurrence of a fire, comprising: a sensor for detecting the occurrence of a fire; a shut-off switch that when opened interrupts for interrupting the supply of electricity to the burner of the cook-stove; a source of current for the shut-off switch; an audible alarm connected to the sensor to emit an audible signal upon the sensor detecting a fire; an interface arrangement disposed between the source of electric current for the shut-off switch and the shut-off switch, the interface arrangement being external to a control panel; an electrical connector at the interface arrangement, and a hardwire connection for connecting the electrical connector on the interface arrangement to the shut-off switch when the alarm is not acoustically connected to the shut-off switch, and a sonic receiver separate from the shut-off switch for acoustically detecting the occurrence of an alarm signal the sonic receiver generating an output signal to an electrical connector attached thereto when connected to the connector on the interface arrangement so as to operate the shut-off switch acoustically when the sonic receiver replaces the hardwire connection.
