Abstract (en)
[origin: EP3179459A1] A slave (10) for an automatic fire alarm system (A1) electrically connected to a pair of electric wires to which a voltage is applied includes a storage (17), a communicator (14) and a processor (19). The storage (17) stores identification information unique to the slave. The communicator (14) receives a synchronization signal transmitted from a master (20) in order to synchronize with another slave (10), the synchronization signal being a signal indicated by a change in the voltage applied to the pair of electric wires. The processor (19) performs a fire detection operation by using a consumption current supplied from the master (20) in an operation time slot allocated according to the identification information stored in the storage (17) when the communicator (14) receives the synchronization signal.
