Introduction
The alarm panel is part of the Live tab, and sorts alarms into five categories:
Live Alarms: alarms that are active, and indicate a rule is currently being broken.
Pending Acknowledge Alarms: alarms that have been cleared but require manual acknowledgement by a user.
System Alarm: alarms concerning the system e.g. network connection, radar connection, Track Engine health etc.
Tracks: the recorded history of a detected target within a defined area.
Retained Tracks: if Track Retention has been enabled, tracks that trigger alarms are retained for a temporary period of time, and can be located on the PPI and examined in this time period.
