Concept
Acknowledgements
When an alarm is triggered, you acknowledge the alarm to indicate to other users that you have responded to the alarm and intend to troubleshoot the problem that caused the alarm. The name of the user that acknowledges the alarm is displayed in the Alarms pane, Events pane, Alarm Views, and Event Views.
Alarms can be configured to be acknowledged in different ways. The transition between alarm states depends on the Basic evaluation property of the alarm.
No Acknowledge
When you select the acknowledgment type No acknowledgement, the triggered alarm returns to normal state and disappears from the alarm view when the monitored variable no longer meets the criteria to trigger the alarm. You select this user action when the user only needs to see a status and does not need to take any action on the alarm, for example, to see if a space is occupied or not.
For more information, see No Acknowledgement .
Single Acknowledge
When you select the acknowledgment type Single acknowledgment, the user needs to acknowledge the alarm in the alarm view before the alarm returns to normal state and disappears from the alarm view.
For more information, see Single Acknowledgement .
Extended Acknowledge
When you select the acknowledgement type Extended acknowledgment, the user needs to acknowledge the alarm in the alarm view in reset state, before the alarm returns to normal state and disappears from the alarm view.
For more information, see Extended Acknowledgement .
System Information Alarms
No acknowledgement type can be set for simple system alarms. You have to acknowledge the alarm to send it back to Normal state. If you do not acknowledge the alarm, it remains in Alarm state. For more information, see System Alarms .
