PURPOSE: A distributing board is provided to help a user to easily mange an emergency situation by digitalizing the number of the distributing board to monitor the state of the distributing board. CONSTITUTION: In a distributing board, a wire detection sensor(201) detects the frequency component in a current passing though a wire and also senses the temperature inside the distributing board. A sensor(202) detects the invasion of animals into the distributing board. An A/D converter(203) converts an analog signal which is detected from the frequency component, temperature, and an analog signal into a digital signal. A controller(204) determines whether the digital signal is an electric fire signal or not. An alarm unit(207) transmits electric fire information to outside through the controller. |
