4.3.5-1 User-Selectable Alarm System Configuration

If the alarm system provides user-selectable operational configurations, then these configuration changes should be coupled with an indication of the present configuration.

Additional Information:
Alarm systems 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. Another example may be operator selection of an alarm message suppression mode in which low priority messages are not presented via the alarm displays but may be accessed through operator action. It is important that the alarm system informs the operators that a requested change in system configuration has been successfully achieved. In addition, a prominent display of the present configuration should be available.
