| Ack Required | true or false |
Indicates that any alarm assigned to this alarm class requires acknowledgment. Only selected component state transitions (normal to offnormal, fault or alert) require acknowledgment. |

| Total Alarm Count | read-only | Reports the total number of alarms assigned to the alarm class from all sources. |
