<P>PROBLEM TO BE SOLVED: To provide an alarm device which preferentially maintains a function of an abnormal alarm output of itself and minimizes battery consumption related to functions other than that when an abnormality is detected even in a normal state of a battery voltage. <P>SOLUTION: An alarm device 10-1 operating with a battery power supply 40 outputs an alarm indicating an interlocking source from a notification section 36 when a fire or an event other than a fire is detected by an alarm processing section 60, and transmits an interlock signal to other alarm devices through a transmission control section 62 to output an alarm indicating an interlocking destination. When a battery voltage is at a prescribed level or higher and an event other than a fire is detected, a prescribed first reception mode is set by a reception control section 64 to receive the interlock signal from other alarm devices. When the battery voltage is at a prescribed level or higher and a fire is detected, a second reception mode in which power consumption is smaller than that in the first reception mode is set by the reception control section 64 to receive the interlock signal from other alarm devices. <P>COPYRIGHT: (C)2013,JPO&INPIT |
