Abstract
An interlocking source alarm output processing unit outputs alarm indicating an interlocking source and transmits event signal indicating the abnormality to other alarm device. An interlocking destination alarm output processing unit outputs alarm indicating an interlocking destination. An interlocking source alarm stop processing unit transmits the event signal and stops an output of the alarm, upon detecting an operation to an alarm stopping unit while outputting the alarm indicating the interlock source. An interlocking destination alarm stop processing unit stops an output of the alarm indicating the interlocking destination and transmits the event signal for stopping the alarm, when an operation to the alarm stopping unit is detected while outputting the alarm indicating the interlocking destination, while the interlocking destination alarm stop processing unit stops an output of the alarm indicating the interlocking destination, when the event signal from the other alarm device is received.
