4.2.6.3-2 Auditory Coding of Remote Alarms

Auditory coding techniques should be used when the workstation associated with the alarm is not in the main operating area.

Additional Information:
During off-normal conditions, the designer should consider the suppression of the auditory code for those alarms that (1) do not require immediate response and (2) do not indicate a challenge to plant safety and technical specifications. This will prevent operators from being distracted by less important alarms while attending to more significant ones.
