PROBLEM TO BE SOLVED: To easily perform operation for inspection alarms in an alarm device such as a fire alarm in a user's own house or an alarm device in a nearby house. SOLUTION: A radio unit 20 is connected to an interlocking connector 8 of a fire alarm 10. A message instructing the start of an inspection alarm and the stop of the inspection alarm is transmitted from a remote controller by a remote controller message similar to a message in the radio unit 20. Since the radio unit 20 can perform transmission/reception with a radio unit in another fire alarm, the radio unit 20 can perform operation for inspection alarms interlocking also with the alarm device in a nearby house.
