Presence sensors contribute to energy savings by detecting the presence or absence of people in a space. This means that lighting, heating, ventilation and other systems can be automatically adjusted according to this detection. By reducing unnecessary energy consumption, NEXELEC presence sensors contribute to significant energy savings and lower energy costs.

A presence detector is a device that detects the presence of people in a given area for a defined period of time. NEXELEC presence sensors are designed to react quickly to movements and provide precise data on the actual occupancy level of spaces.

To reduce noise pollution, it is useful to implement corrective measures: Use quiet machines Soundproof premises or buildings Equip occupants with earplugs Create isolated areas for noisy calls or machines. NEXELEC noise and sound level sensors help reduce noise pollution in indoor spaces.

Generally speaking, at 80 dB and above, the danger threshold is considered to have been reached after 8 hours of noise exposure. Above 130 dB, any exposure to noise, even short-term, is considered highly harmful. NEXELEC noise sensors measure the sound environment in interior spaces, helping to ensure the well-being of occupants.

Poor noise management will also have an impact on occupants’ concentration levels, influencing their alertness too. The impact is not only physical, but can also be psychological. Studies show that exposure to noise increases levels of the stress hormone cortisol. This can lead to increased anxiety, fatigue, depression and even sleep disturbance. NEXELEC noise sensors […]

Noise is a constant feature of everyday life. But unfortunately, it can be harmful to humans. In France, 3 million employees are exposed to excessive noise levels in the workplace. Without realizing it, hearing loss can set in very quickly and lead to deafness. To anticipate these risks, NEXELEC noise sensors help you keep an […]

There are several ways to improve light levels: Maximize natural light: make the most of natural light by positioning desks close to windows and using skylights where possible. Natural light helps regulate our circadian rhythm and raises our alertness level. Choose the right artificial lighting: if you need artificial lighting, opt for energy-efficient LED bulbs, […]

In any indoor environment, lighting plays a crucial role in the productivity, concentration and well-being of occupants. Good lighting can boost energy, improve mood and reduce eyestrain. Measuring brightness is therefore essential to guarantee the visual comfort, safety, energy efficiency and functionality of interior spaces.

To secure the product with the FIX adhesive fastener :   Place the adhesive on the mounting base and press firmly with your fingers for 10 seconds. Remove the adhesive backing and stick the mounting base to the wall or ceiling. Press down hard with your fingers for 10 seconds and wait 30 seconds before […]

To secure the base to the wall or ceiling: Use a level to draw a line about 5 centimetres wide on your wall. Position the base on the line with the “UP” marking and the arrows pointing upwards. The small ears on either side of the base should be on the lower edge of the […]

Ceiling or wall installation Install the detector on the ceiling in the center of the room, at least 50 cm from corners, walls, beams or any other obstacle. Install the detector on the wall at a distance of between 50 cm and 60 cm below the ceiling. Fixing to a sloping ceiling Install the detector […]

Sealed-battery detector Follow the commissioning procedure for INSAFE and INSAFE+, ORIGIN and ORIGIN+ detectors: Switch on single-use switch (1) Wait a few seconds, then press the detector button for 3 seconds until the alarm sounds, then release to stop the alarm (2) The detector initializes for 10 minutes. After 10 minutes, the detector is ready […]
