STATE DESCRIPTION
Active This is the initial state of an alarm, which means this alarm is new and no one has
assumed responsibility for handling it yet.
Acknowledged This means that one administrator has decided to respond to the cause of this
alarm. Other administrators see that person’s name in their alarm screen and so
duplicate effort in solving the same problem is avoided.
Cleared After the administrator has solved the cause of the alarm, he/she can clear the
alarm. When an alarm is cleared, it is removed from the current alarm screen and
becomes an historical alarm.
