PROBLEM TO BE SOLVED: To provide a wireless reception repeater and a wireless repeater which flexibly and easily adding or replacing a fire sensor at a low cost by connecting the fire sensor to a sensor line, and causing a fire notification facility for monitoring a fire and a wireless fire notification facility to cooperate with each other. SOLUTION: The wireless reception repeater 16 can be electrically and mechanically attached to/detached from a sensor base 14 by a base fitting structure. The wireless reception repeater 16 establishes an electric interface with the sensor line 12 through the sensor base 14, and when receiving an event signal showing an abnormal state from the wireless sensor 20, supplies notification currents to the sensor line 12 to cause a P type receiver 10 to issue a fire warning. A cable type sensor 18 may be fit into the wireless reception repeater 16, so that a fire can be monitored. COPYRIGHT: (C)2010,JPO&INPIT |
