This object is a bitmask reporting whether the unit's minor and critical alarm contacts are currently active, with both bits starting inactive at power-up. An admin monitors this to catch hardware-level alarm conditions signaled through the unit's physical alarm relay contacts, distinct from the LED status object. For example, seeing the criticalAlarm bit set would indicate a serious fault condition on that wireless link needing immediate attention, versus only the minorAlarm bit being set for a lower-priority issue.
