<P>PROBLEM TO BE SOLVED: To appropriately and promptly deal with the case where a fire occurs while failure alarm sound is outputted from a speaker during a checking operation. <P>SOLUTION: In the case where a check instructing operation using an alarm stop switch 20 under a normal state is detected by an event detection section 58, on the basis of a low-battery failure flag 78 or a sensor failure flag 80 that is failure information stored in a memory 32, a check processing section 74 outputs failure alarm sound indicating a failure source from a speaker 56 of an alarm section 36. In the case where an event signal indicating an abnormality from another alarm is received effectively by the event detection section 58 while failure information is outputted by the check processing section 74, a failure alarm interruption section 76 interrupts the failure alarm sound from the speaker 56 and outputs fire alarm sound indicating an interlock destination. <P>COPYRIGHT: (C)2012,JPO&INPIT |
