IV. 4. alarms - safety devices
IV. 4. 1. alarms
• No volt detection:
In the event of a mains power cut, a continuous audible alarm is tripped.
• Operating fault:
In the case of a distribution fault, an audible intermittent alarm is tripped.
IV. 4. 2. safety devices
• compressor motor:
Thermal safety is ensured by a thermostat situated in the stator winding (145 ± 5 °C).
• Electrical protection of the NewLife ® Intensity :
A circuit breaker is located on the front panel I.1 (2).
• Safety valve:
This is fitted on the compressor outlet and is calibrated to 3 bar.
• 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 NewLife ® Intensity concentrator.
The Oxygen Monitor detects any drop in the concentration below a pre-set level and activates an
audible and visual alarm. A yellow LED indicates a concentration level of below 85 ± 3%.
When the LED is yellow for more than 15 minutes
(± 2 minutes), an intermittent audible alarm is tripped.
Note: when the NewLife ® Intensity is started, the Oxygen Monitor module operates as follows:
1) in addition to the normal NewLife ® Intensity test, the Oxygen Monitor yellow LED lights up.
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 85 ± 3% O
2
.
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 to 85 ± 3%, and there is
no need to alter the settings.
