The invention relates to a danger warning system comprising a central station (Z) and appliances (M<SUB>n</SUB>) which are connected thereto by means of a monitoring line (ML). Each appliance (M<SUB>n</SUB>) comprises an insulator switch (S), an unequivocal identification number, and a communication address. In order to determine the configuration of the danger warning system, the appliances (M<SUB>n</SUB>) that can be decoupled by means of the insulator switch (S) are sequentially started and announced to the central station (Z). In the event of simultaneous announcements of more than one appliance (M<SUB>n</SUB>), only the announcement of one of said appliances (M<SUB>n</SUB>) is accepted. During the announcement of appliances (M<SUB>n</SUB>) at the central station (Z) with the communication addresses thereof, when appliances (M<SUB>n</SUB>) with different communication addresses are simultaneous announced, the communication addresses are differed according to an arbitration method, and the two different communication addresses are sequentially registered. When appliances (M<SUB>n</SUB>) with the same communication addresses are simultaneously announced, the collision of said same communication addresses is identified and resolved. |
