When analarm occurs, it appears in the Alarm List of all users in the user groups configured to receivethat alarm. When any one of these users starts to work on the alarm, it disappears from theAlarm List of all other users.Alarms are displayed on a workstation’s alarm monitor and optionally on analog monitors. Thisbehavior is described in the following paragraphs.Alarm flow1. An alarm occurs in the system.2. Alarm notifications appear in the Alarm Lists of all users configured for this alarm. Alarmvideo is immediately displayed on configured monitors. If it is an automatically displayedalarm (auto pop-up), the alarm video is also automatically displayed on the OperatorClient workstation’s alarm monitors.If the alarm is configured as an auto-clear alarm, the alarm is removed from the Alarm Listafter the auto-clear time (configured in the Configuration Client).On analog monitors, any quad views from VIP XDs are temporarily replaced by full-screendisplays.3. One of the users accepts the alarm. The alarm video is then displayed on this user'sworkstation (if it is not already displayed via auto pop-up). The alarm is removed from allother Alarm Lists and alarm video displays.4. The user who accepted the alarm invokes a workflow that can include reading an actionplan and entering comments.
