
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.
