Abstract

PURPOSE: To discover fire outbreak regions quickly and let the discovery of faulty detectors to be performed by letting each fire detector output at respectively different output voltages and different periods at the sensing of fire, detecting these with a supervising unit and checking the operations of the individual detectors.
CONSTITUTION: Fire detectors FD1...FDn vary respectively in output power and output voltages at different periods at the detecting of fire. On the other hand, the respective output voltages of the respective detectors FD1...FDn are detected 21 in a supervising unit 10 and the operations of the individual detectors FD1...FDn are checked. Hence, the discovery of the fire regions at the outbreak of fire may be rapidly performed and the fault of each detector installed may be discovered
