Sound Control Priorities
When the audible alarms are re-enabled, and at least one alarm
condition exists, the sound cycle for the highest priority alarm
condition in effect at that time will be started.
Note: The critically low battery state overrides the audible alarm
disable. If a critically low battery condition occurs and the audible
alarms are either temporarily or permanently disabled, the audible
alarms will become re-enabled. A medium priority alarm will sound
unless there is a high priority alarm condition in effect.
Informational beeps will occur only during the "quiet" part of any
alarm sound in progress (or the beep volume can be set to OFF).
