Alarm missing response system and alarm missing response method

摘要

[Problem] To propose a highly accurate scheme for addressing lost alarms.[Solution] A lost alarm addressing system includes communication devices (11) configured to transmit an alarm to a management device (20) and transmit a number-of-alarms notification for notifying the number of transmitted alarms to the management device (20), and the management device (20) configured to count the number of alarms received from each of the communication devices (11), collate the counted number of alarms with the number of alarms notified using the number-of-alarms notification, and cause the communication device (11) to retransmit a lost alarm when the two numbers of alarms do not match. Further, the management device (20), when the management device (20) does not receive the number-of-alarms notification within a predetermined time after receiving the alarm from the communication device (11), causes the communication device (11) to retransmit the lost number-of-alarms notification.
