Option 3.2.1. Ack Button: Alarm ID Acknowledged

A user can acknowledge an alarm to inform other users that the alarm has been seen and, if necessary, the condition that set off the alarm is being investigated and worked on.

How the Alarm Viewer responds when a user clicks Ack, depends on what was configured on the Alarm Options tab in the Alarm Definition (or Point Properties) dialog box.
