Acknowledgment (or confirmation) should be required if a significant alarm system configuration change is to be made automatically.
Additional Information:
Alarm systems may allow users to select alternative functional configurations of the alarm system under some alarm situations, such as automatic silence of auditory alerts for lower priority alarms under high-alarm conditions. It is important that the alarm system informs the users that a requested change in system configuration has been successfully achieved. In addition, a prominent display of the present configuration should be available.
