6.3 Alarm Log and View History
The number of active alarms showing in the upper right corner of the screen next to the bell icon, reflects the number of active
alarms without including alarms that have been acknowledged “ACK” and muted “MUTE.”
The number of active alarms on the Alarm page (when the bell icon is clicked) is counting all active alarms including alarms that
have been acknowledged “ACK” and muted “MUTE.” Therefore there may be a difference between these two alarm counts.
Select the Active Alarms icon to open the Alarm Log screen and view the list of active alarms in the system:
The alarm name appearing in the Description column is the default name or custom name assigned to the alarm. Click View
History to see the collection of alarms that have been resolved.
Active alarms also appear as default on the Home screen.
