The detector features Air 360° technology for ambient air analysis. Featuring large openings at the rear, this exclusive design allows gases to flow into the heart of the product for fast, reliable analysis.

By entering the detector, insects can disrupt the device and cause false alarms. The device is therefore equipped with reinforced anti-insect protection. The product’s external design forms a barrier that effectively limits the entry of large insects.

The product features a powerful audible alarm, with a range of 85dB at 3m. By way of comparison, this represents the same sound volume as a TGV passing through your corridor.

Frequently Asked Questions

Our experts answer your questions

Check beforehand the precautions and limits of use of the detector, as well as the maintenance recommendations given in the user manual.

The presence of dust, the immediate proximity of an artificial light source, or nearby air movement caused by a convector, air-conditioning or ventilation unit, can cause the detector to go off for no apparent reason.
To maintain it, simply clean your detector (at least once a year) using the brush attachment of a vacuum cleaner and, if necessary, change its location.

Do not install the smoke detector in :

  • Less than 1.5 m from lighting fixtures: ceiling lights, incandescent, halogen or fluorescent lamps, etc.
  • A place where the detector is exposed to direct sunlight
  • Close to or above heaters, windows or other equipment that can generate air flows
  • Proximity to stray fumes: chimneys, furnaces, boilers, combustion radiators, etc.
  • A place where the temperature is below 4°C or above 45°C. A place where humidity is below 10% or above 95%: bathroom, laundry room, etc.
  • A dusty or dirty area: garage, workshop, etc.
  • An insect-infested or outdoor location

The detector emits a beep

If the detector beeps every minute, this indicates a low or discharged battery.
There are several reasons for battery discharge:

  • Failure to maintain the detector (dust at least once a year)
  • Repeated false alarms or sub-optimal operating conditions

 

The detector emits three beeps

Three repetitive beeps every minute or so indicate that the detector has detected a fault in its smoke sensor. Follow the test procedure below to clean and test the detector:

  • Remove the detector from its base (1/4 turn to the left).
  • Clean the detector using the brush attachment of a vacuum cleaner to remove any dust that may have accumulated and interfered with the product’s operation.

  • Check detector operation. Press the central button for at least 3 seconds:

    • Case 1: If the detector emits a loud beep and the Red LED flashes, the detector is functional and should be reinstalled on its mounting base.
    • Case n°2: If the detector does not sound and the Red LED flashes dimly, the battery is low and the detector must be replaced.
    • Case 3: If the detector does not sound and the Red LED does not flash: wait 2 minutes.
      If the detector emits 3 consecutive beeps every minute, the sensor is faulty and the product must be replaced. If the detector does not beep, the battery is empty. The detector is no longer operational and must be replaced.

Our sealed-battery detectors are fitted with a battery with a maximum life of 10 years under normal conditions of use (with proper product maintenance). The detector battery is not replaceable. The end of battery life means you need to replace your detector.

On replaceable-battery detectors, you can change the battery whenever you need to. The product’s end-of-life is reached after 10 years of operation. End-of-life means that you must replace your detector.

Recycling the detector: A used detector is electronic waste and must be recycled. The detector must be deposited in a dedicated collection bin available from supermarkets, household appliance stores or waste collection centers.
If the detector is replaced by an identical product, the new detector must be compatible with the existing mounting base.
