 Rearm Sensors
The rearm is a request for the event status for a sensor to be rechecked and updated
upon a transition between good and bad states. Rearming the sensors can be done
manually or automatically. This column indicates the type supported by the sensor. The
following abbreviations are used to describe a sensor:
- A: Auto-rearm
- M: Manual rearm
 Default Hysteresis
The hysteresis setting applies to all thresholds of the sensor. This column provides the
count of hysteresis for the sensor, which can be 1 or 2 (positive or negative hysteresis).
 Criticality
Criticality is a classification of the severity and nature of the condition. It also controls
the behavior of the Control Panel Status LED.
 Standby
Some sensors operate on standby power. These sensors may be accessed and/or
generate events when the main (system) power is off, but AC power is present.
