The Unacknowledge Alarms permission defines whether a user account or User Group has access to the Unacknowledge Alarms action for a database item. When available, this action can be used to undo an Acknowledge Alarm action that has been performed on an alarm that has not been cleared. It also applies to the Unacknowledge with Comment action.
For more information, see Unacknowledge an Alarm in the ClearSCADA Guide to Alarms and see Unacknowledge an Alarm with Comment in the ClearSCADA Guide to Alarms.
Availability: Can be restricted via the Permission Restrictions settings (see Define whether any Permissions are Restricted). By default, the Unacknowledge Alarms permission is restricted on a per server basis.
