Alarm Suppressing Sub-Menu
Here you can modify the Alarm Suppression relationships of an alarm signal.
Alarm Suppression Explanation:
If Alarm A suppresses Alarm B, when Alarm A occurs, Alarm B will not be reported even if the conditions
of Alarm B are met. For example, AC failure alarm will suppress AC low voltage alarm. When AC failure occurs, the alarm conditions for
both AC failure alarm and AC low voltage alarm are met, and both alarms should be reported. However, since the AC failure alarm
suppresses the AC low voltage alarm, only AC failure alarm is displayed in the alarm list.
To configure Alarm Suppression, first select the device to which the alarm signal belongs. This displays all the alarm signals of this device.
Locate the alarm signal to be configured for Alarm Suppression and click on the “Modify” button for this alarm signal.
