For AERO, AERO Lite, AERO CO2, CARBON, SENSE, ATMO models. The calibration process is performed automatically by the device every 8 days. No maintenance required. The reliability of CO2 measurements is guaranteed throughout the product’s lifetime. You can also calibrate the CO2 sensor manually: 1. Place your product near an open window for at least […]

NDIR (Non-Dispersive Infrared) sensors offer highly accurate measurement of CO2 levels. They use infrared spectroscopy to specifically detect CO2 molecules, enabling reliable and consistent measurements. NDIR sensors are designed to maintain their calibration and accuracy over long periods, making them a durable choice for continuous monitoring of CO2 levels. NDIR sensors are effective and reliable […]

Correct ventilation of communal areas helps reduce the risk of viruses spreading through the air. Measuring CO2 levels enables you to quickly check the quality of air renewal, and encourages occupants to air the room if necessary. CO2 can cause headaches, drowsiness, difficulty concentrating, mild nausea and rapid heart rate. NEXELEC’s CO2 sensors provide reliable […]

Moisture comes from a variety of sources, including human activity, breathing and architectural design problems. Air that’s too dry dries out the respiratory tract, and humidity that’s too high promotes allergies. Ideally, the humidity level in an enclosed space should be between 40% and 60%.

The heat detector (DAAT) identifies rapid temperature changes that could indicate the start of a fire. This product monitors rooms such as kitchens, garages and laundry rooms, where smoke detectors (DAAF) cannot be installed.    

The REMOTE and REMOTE+ remote control is used to operate ORIGIN, ORIGIN+ smoke detectors or AIR, AIR+ carbon monoxide detectors. The remote control can stop the alarm and/or put the detectors on standby for a few minutes. A single REMOTE or REMOTE+ remote control can operate the detectors in all homes. The REMOTE remote control […]

Our detectors are certified by the LNE (Laboratoire National de Métrologie et d’Essais), giving them a high level of safety and performance. Factory-tested, our products are compatible with regulatory devices.

In an enclosed space, heat rises and stagnates at the ceiling, where the temperature is de facto a little higher than in the rest of the room. To ensure correct measurement of ambient temperature, we recommend mounting the detector on a wall 50 cm below the ceiling.

The detector can emit various visual (LED flashing) and/or audible (beep) signals: Normal operation: one green/minute LED flash Audible alarm mode: one red LED flash/second + one beep/second Audible alarm pause mode: one red LED flash/second Low battery: one flashing orange LED + one beep/minute Malfunction: one green LED flash/minute + two orange LED flashes/minute […]

The carbon monoxide detector (DAACO) can quickly detect high concentrations of this gas in the air and warn occupants of a room so they can take appropriate action. This gas is odorless, invisible and toxic: inhaling CO can trigger headaches, fatigue, nausea and vomiting, and can even be fatal. Carbon monoxide emissions   The source […]

To interconnect ORIGIN / GUARD smoke detectors or AIR carbon monoxide detectors, simply press : Press the central button of the first detector twice Press the central button of the second detector twice An orange LED appears on each product. When the devices are connected, the LEDs on both detectors go out. To add an […]

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 […]
