Table 5: Audible Indicator Sound Control Priorities
Normal sound operation; steadily illuminated low battery
indicator only.
Medium priority audible alarm unless a prior high priority patient
alarm is "latched". When "latched" it will sound a high priority
patient alarm.
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.
The medium priority sound cycle will not be restarted should a
new equipment alarm condition occur; the existing sound will be
maintained.
The onset of a high priority patient alarm condition will cause the
initiation of the high priority patient alarm.
If a medium priority equipment alarm condition occurs after the
onset of a patient alarm condition, the patient alarm state will be
latched and will not be overridden by the equipment alarm.
When the patient alarm condition is cleared and there is an
equipment alarm in effect, then the medium priority sound will be
started.
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".)
