11.1 Stage 1 Functional testing
11.1.1 Complete Power Fail Alarm Test.
Step 1 The ventilator has a complete power fail alarm. This alarm is activated when both
mains power and back-up battery power fail. This alarm is a high pitched,
continuous tone emitted by the ventilator in the event of complete power failure.
Turn ON the ventilator allow the start up screen to clear and wait for it to enter the
Ventilation Off mode.
Calibrate Flow Sensor (for this calibration there is no need to occlude the flow
sensor).
Turn the ventilator OFF at the mains power switch
located on the rear of the machine.
This will trigger the mains power fail alarm.
Slowly depress the battery power termination
switch. Before the switch reaches the end of its full
travel, the audible complete power fail alarm
should be initiated. Once the alarm has been
triggered release the button, the alarm should
continue.
Re-press the battery power termination switch
fully to cancel the alarm.
Turn ON the ventilator and wait for it to enter the ventilation off mode.
