Audible Alarms
When an alarm condition exists, the ventilator will generate a sequence of
audible tones to alert the operator. The sequence varies according to the
urgency and priority level of the alarm:
• High Urgency: The ventilator emits a repeating sequence of five tones.
• Medium Urgency: The ventilator emits a repeating sequence of three
tones.
• Low Urgency: No audible tone emitted. (Med/Low indicator
illuminates and alarm messages appear in the front panel Alerts
window)
When more than one alarm is active, only the highest urgency level alarm is
audibly annunciated. Procedures for silencing audible alarms are described
below.
Alarm Silence
To silence alarms, perform the following:
• Press the ALARM SILENCE key on the front panel. The audible tone
will cease and the alarm silence indicator will illuminate and remain
lit for two minutes. Specific alarms that cannot be silenced are listed
in Table 9-1: “Alarm Alert Messages”.
When ALARM SILENCE is pressed before the end of the two-minute period,
the two-minute timer is reset, and alarm silence begins anew. Pressing ALARM
SILENCE multiple times does not give multiple two-minute silence periods.
If new alarms occur during alarm silence, all visual alarm annunciation
continues. If the Alerts insert is not present, it will appear. The message for
any alarms that occur during the alarm silence period will appear in the Alerts
insert if there are fewer than three messages currently displayed or the new
