PURPOSE:To cut off power supply to an oil feeder automatically to prevent a fire and to report and intrusion, by judging the identity between a stored number and a dialed number to generate a prescribed output. CONSTITUTION:Specified numbers such as ''110'' and ''119'' are stored in a storage circuit 3, and one terminal of the circuit 3 is connected to a terminal 9a of an output terminal 9, and the other terminal is connected to a terminal 9b. When a fire occurs in an oil station, a transmission signal A is supplied to a judging circuit 2 of a transmission destination confirming device 22 in accordance with the operation of a dial 1; and if it coincides with contents of the storage circuit 3, an output signal H passes through the terminal 9a to cut off power supply to the oil feeder. Simultaneously, an output signal D of a control circuit 4 is sent to a transmitting/receiving circuit 5 to make the communication with a fire station possible. In case of the intrusion, when it is reported to the police by calling ''110'', a burglar buzzer sounds in associating with this reporting. |
