This option is disabled if the AllowAckSelected property is set to False.
The All events of the current filter option is only available if there are visible alarms on this E3Alarm. Users can select this option without clicking any alarm. To do so, click any area on this E3Alarm and the Acknowledgment window is then displayed. When clicking it, the acknowledgment dialog box appears. This option is disabled if the AllowAckCurrentFilter property is set to False.
The All events in the system option is always available, even if there is no visible alarm on this E3Alarm. This option is disabled if the AllowAckAll property is set to False.

For this option, the only item available is All events in the system, that is, all alarms not linked to an Alarm Source are removed. This contextual menu option of E3Alarm is disabled if the AllowDeleteUnboundAlarms property is set to False.
NOTE |
An alarm is considered unbound when it is present on alarm summary but its Alarm Source was deactivated. Unbounded alarms can occur in some situations, such as when changing an Alarm Source's name, when using the Deactivate method on an Alarm Source on a script, or when removing an Alarm Source. |
Alarm acknowledgment can also be performed by clicking or double-clicking an alarm's row. To do so, specify in the properties of a column, on E3Alarm's Properties Window, Columns tab, Properties option, the way to acknowledge this alarm at run time, by clicking or double-clicking its column.
