Always read the user manual

Before handling, read the manufacturer's recommendations: each model may have specific maintenance, cleaning or positioning requirements.
Observe instructions on use limitations, ambient temperature and areas to be avoided.

 

Clean your detector once a month

Monthly cleaning is recommended to prevent the build-up of dust that can interfere with the sensors.
Here's how:

  • Use a clean, dry cloth or the brush attachment of your vacuum cleaner.
  • Do not apply any chemicals, solvents or detergents.
  • Never paint the detector.

 

Beware of sources of interference

Certain elements may cause the detector to trip unexpectedly:

  • A direct artificial light source (neon, powerful LEDs)
  • Close proximity to a ventilation, air-conditioning or convector outlet
  • Rapid temperature variations

If necessary, change the detector's location according to the manufacturer's recommendations.

 

 

Test operation regularly

Once a month, press the detector 's test button to make sure the alarm is working properly.
This test validates the state of the electronic components and ensures that the device is always operational.

 

Who is responsible for maintenance?

In the case of residential property, the occupant (tenant or owner-occupier) is responsible for maintaining the CO detector.
This responsibility is part of the ALUR law, which imposes certain obligations in terms of housing safety.
