Symbol of Nexelec's know-how
ATMO is the most complete detector of our range. This 10-in-1 sensors provides information on the air quality and the working environment of your teams. ATMO can discriminate specific Volatile Organic Compounds (VOC) such as formaldehyde (HCHO).

Spot high concentrations of Formaldehyde
Formaldehyde is frequently present in the indoor air of buildings due to air pollution linked to certain coatings, floors, or furniture.
ATMO will continuously analyse formaldehyde emissions to help you identify the most exposed spaces.

Control exposure to VOCs
Volatile Organic Compounds (or VOCs) are characterized by their high volatility and spread easily in the atmosphere.
VOCs can induce nausea and contribute to olfactive pollution.
ATMO will continuously measure VOCs and characterise their evolution over time in order to help ventilate the premises at the right time.
Your workspace under control
With its multi-parameter measurement sensors, SENSE is specifically designed to analyse the working environment and thus quickly identify possible improvements.
Thanks to its microphone, capable of determining the average noise level and the noise peaks, SENSE keeps track of working conditions.
The light and motion sensors allow to determine the real activity rate of the spaces to adapt the heating and ventilation strategies of the buildings accordingly.

Warning
In collective spaces, the display of the CO2 level on a screen is potentially stressful for users and can make it harder to interpret the measurements.
The Green / Orange / Red indicator simplifies immediate understanding and the implementation of actions adapted to the air renewal.
The detector's indicator light is fully configurable.
Simply download the free App.Nexelec application from the Google Play Store on your Android smartphone and configure your detector in "contactless" NFC to change the thresholds that trigger the indicator light.
By default, the light turns Orange at 1000 ppm and Red at 1700 ppm

Does your detector emit a single repetitive beep approximately every 45 seconds?This beep is a signal of a low or discharged battery. There may be several reasons for the battery draining. A lack of regular maintenance of the detector, such as the non-dusting (at least once a year) recommended in the detector's user manual, affects battery life. Without any maintenance for several years, the battery of the detector can discharge more quickly. Repeated false alarms or sub-optimal usage conditions can also impact battery life. For security reasons, your detector is fully sealed and cannot be dismantled. The battery is not replaceable. A dead battery requires you to replace your smoke detector. For detectors manufactured between 2014 and 2015 (date of manufacture indicated on the back of the detector), the depleted battery is not covered under the 10-year warranty. The conditions of application of the 10-year warranty are clearly indicated in the user manualsupplied with the detector.

Why is my detector beeping ?1.1- My detector beeps If the detector beeps every minute, it means that the battery is low or discharged. There are several reasons why the battery may be discharged: - A lack of maintenance of the detector (dusts must be removed at least once a year) - Repeated false alarms or non-optimal operating conditions 1.2- My detector emits three beeps Three repetitive beeps every minute indicate that the detector has detected an issue in its smoke sensor. The following test procedure should be followed to clean and test the detector : 1. Remove the detector from its base (1/4 turn to the left). 2. Clean the detector with the brush tip of a vacuum cleaner to remove any dust that may have accumulated and interfered with the product's operation. 3. Check the operation of the detector. Press the central button for at least 3 seconds : Case n°1: If the detector emits a strong sound signal and the red light diode flashes, the detector is functional and must be reinstalled on its mounting base. Case n°2: If the detector does not beep and the red LED flashes weakly, the battery is low and the detector should be replaced. Case n°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, then the detector has a sensor fault and the product must be replaced. If the detector does not beep, then the battery is empty and the detector must be replaced.
