Claims

[Scope of Claim for Utility Model Registration] (1) A smoke sensor that detects smoke generated in electrical equipment, and a cutoff circuit that operates upon receiving the output of this smoke sensor and stops power supply to the electrical equipment. Safety equipment for electrical equipment. (2) The safety device for electrical equipment according to claim 1, wherein the cutoff circuit has a single-action type configuration that completes its mission upon receiving the output of the smoke sensor. (3) The safety device for electrical equipment according to claim 1, further comprising a notification means for receiving an output from the smoke sensor and giving audible notification that the cutoff circuit has been activated. (4) A central monitoring device that monitors and controls multiple electrical devices via power lines, a smoke sensor installed in one electrical device that detects smoke generated inside, and a smoke detection signal from this smoke sensor. A control adapter for transmitting data to the central monitoring device and stopping power supply to the electrical device incorporating the smoke sensor upon receiving a reply from the central monitoring device. (5) A central monitoring device that monitors and controls multiple electrical devices via dedicated signal cables, a smoke sensor installed in one electrical base machine that detects smoke generated inside, and a smoke sensor for this smoke sensor. A safety device for electrical equipment, comprising a terminal controller that transmits a signal to the central monitoring device and stops power supply to the electrical equipment incorporating the smoke sensor in response to a reply from the central monitoring device.
