External Power Low / Disconnect
Alarm triggers when the external power (either AC or DC) drops below minimum
level (~11 VDC as supplied by either the AC/DC Power Supply or a direct DC
source) or power is intentionally disconnected. Since the device operates with
either external power or using its internal battery this is a low priority alarm that
clears when the user presses the Mute/Cancel button. Pressing the Mute/Cancel
button is the user’s acknowledgment that the device is operating on internal
battery. If this alarm occurs and the user believes that the device is still
connected to external power the user should investigate the external power
source and contact the service center for additional information.
Mitigation/Info: Internal Battery Operation, Check Power Connection/
Supply, Monitor Battery Status **Contact Service Center**
3422
Battery Fault - Battery Power Not Available
Alarm triggers when the internal battery has been removed or communication
between the battery and CPU has failed. When external power is applied the
device is capable of operation however, loss of external power will result in loss
of ventilation and a high priority alarm. Operating in this state should only be
done when no other alternatives are available.
Mitigation/Info: Battery Power Not Available, DO NOT Remove External
Power!, Maintain External Power **Contact Service Center**
3423
Battery Charging Fault
Alarm triggers when the battery charging circuit fails. When this alarm is active,
the battery cannot be charged. The device can only run with external power. If
power is lost, ventilation will stop and a high priority alarm will trigger. Operating
in this state should only be done when no other alternatives are available.
Contact the service center for additional information.

Low Battery - < 30 Minutes Operation
Alarm triggers when the device detects that there is < 30 minutes of battery
operation remaining and no external power is connected. The user should seek a
source of external power and/or plan to provide manual ventilation. Attaching
external power will immediately clear the alarm however, alarm #3431 will occur
in its place, see below.
Mitigation/Info: < 30 Minutes Operation, Connect External Power,
Ensure Ability to Manually Ventilate, **Contact Service Center**

Low Battery - < 30 Minutes Operation
This triggers when external power is connected to a device that has an internal
battery that has drained to a low battery status. The device is warning the user

backup. This alarm will resolve when the internal battery charge has > 30
minutes of operation. The user must maintain constant monitoring of the device
and the patient during this period.
Mitigation/Info: < 30 Minutes Operation, Operating With External Power,
Continue Charging With External Power, Ensure Ability To Manually
