The State property represents if the alarm is Active or Inactive and Acknowledged or Unacknowledged.  Below are the possible values and meaning for the State property in OPC A&E.

1 = Inactive and Unacknowledged
3 = Active and Unacknowledged
5 = Inactive and Acknowledged
7 = Active and Acknowledged
