PROBLEM TO BE SOLVED: To provide a radio communication system for reducing the possibility of erroneously registering an address of a radio station belonging to a different group.SOLUTION: Radio signals are transmitted/received between a plurality of fire alarms TR1 and TR2 through a radio wave, where unique identification codes are assigned to the fire alarms TR1 and TR2 respectively. The fire alarms TR1 and TR2, whose memory units 1a store unique identification codes of their own alarm and communication partner in advance, perform radio communication by identifying at least either of a transmission source and transmission destination by using the identification codes. When the fire alarms TR1 and TR2 perform radio transmission of their mutual identification codes and register them in system construction, a fire alarm on the transmission side transmits a radio signal including an identification code of the fire alarm on the transmission side with a predetermined transmission gain lower than that in normal operation time to a fire alarm on the setting destination side, and the fire alarm on the setting destination side acquires the identification code from the received radio signal and registers the code with the memory unit 1a. |
