Acknowledgement-required and self-clearing alarms

Overview

What are cleared alarms?

An alarm “clears” when the criteria for an alarm are no longer met and it is not an alarm that requires acknowledgment.

A cleared alarm no longer appears in the alarm overview. However, a cleared alarm always appears in the ↗ alarm history.

Alarms CANNOT be deleted from the alarm history.
