IV. 4. Alarms - Safety devices
IV. 4. 1. Alarms
• No volt detection:
In the event of a mains power cut, an audible intermittent single alarm is tripped.
• Operating fault:
In the case of a distribution fault, an audible intermittent multiple alarm is tripped.
IV. 4. 2. Safety devices
• Compressor motor:
Thermal safety is ensured by a thermostat situated in the stator winding (135 ± 5°C (275°F)).
• Electrical protection of the VisionAire
A circuit breaker is located on the front panel Fig. I.1 (2).
• Safety valve:
This is fitted on the compressor outlet and is calibrated to 280 kPa.
• Class II devices with insulated casings (IEC 601-1 standard).
IV. 5. Oxygen Monitor function (optional - mandating for Europe and
certain other countries)
IV. 5. 1. Oxygen Monitor operating principle (oxygen concentration indication module)
The Oxygen Monitor is an electronic module capable of checking the effective oxygen
concentration supplied by the VisionAire
The Oxygen Monitor detects any drop in the concentration below 82% ± 3% and activates an
audible and visual alarm. A yellow LED indicates a concentration level of below specification.
When the LED is yellow for more than 15 minutes, an audiible intermittent multiple alarm is tripped.
Note: when the VisionAire
1) in addition to the normal VisionAire
2) in principle, the LED remains lit for a few minutes (10 minutes at maximum) until the
concentration of the gas supplied reaches and exceeds specification.
3) The yellow LED is extinguished after this period, showing that the concentrator is operating
satisfactorily.
IV. 5. 2. Maintenance of the Oxygen Monitor module:
- No special maintenance is required, The alarm trigger is factory pre-set and there is no need to
alter the settings.
IV. 5. 3. Enviromental Limit Conditions:
- Concentrator limits apply.
