The Alarm Mute button temporarily resets the audible Low Pressure/Power
Failure/Service alarms. Should the situation not be resolved and the fault condition
continues the alarm will resume notifying carer.
9. Alarms & Fault Findings
The system is equipped with audible and visual alarm indicators. These alert the user to the status of
the available mains supply and any mattress defect.
9.1
Low pressure alarm
Upon detection of low pressure, an audible alarm will be heard and the Low Pressure indicator will
illuminate. The audible alarm may be cancelled by touching the Alarm Mute button. The Low
Pressure indicator will continuously illuminate until the low pressure fault condition is resolved.
This condition could be caused, for example, by incorrect fitting of the air pipe connector, opening of
the CPR valve or a leak in the mattress due to a cut or puncture.
9.2
Power failure alarm
If at any time the mains power should be removed from the power unit or the power cable is
unplugged without turning the power unit OFF, an audible alarm will be heard and the Power Failure
indicator will illuminate. The audible alarm may be cancelled by touching the Alarm Mute button.
The mattress is capable of supporting the patient in static mode for a period of time.
