Types of Alarms - viewLinc 5.1

Alarms indicate issues that may require immediate resolution, provide notification about interruptions in communication between devices or hosts and the viewLinc Enterprise Server, updates about system status or configuration changes, and reminders about upcoming maintenance requirements.

Alarms are viewable in the Alarms window (device and system alarms and threshold alarms for Locations you have permission to view), the Sites window (device and threshold alarms for the Locations you have permission to view), or in the Overview window (device and threshold alarms for the Locations assigned to your views).

All alarm events are recorded in the event log, to ensure a secure audit trail.
