Niko PIR presence detector Swiss Garde 180 Master UP IP20, White

Infrared presence sensor for wall mounting. Detection range of up to 8 m (in a radius of 176°). Full and semi-automatic modes as well as corridor mode for all application areas. Master presence detector with integrated push button. Timer with built-in short pulse function. Operating temperature: -10 °C to 45 °C. Can be combined with slave ceiling and wall detectors. Detects relevant movements using a PIR sensor. The sensor with PIR technology - PIR stands for passive infrared - responds to minimal local temperature changes that it perceives as infrared light with a specific wavelength. This allows it to register people, vehicles, and animals entering the detection area while ignoring swirling leaves or moving branches. It also disregards fluctuations in general temperature, such as those caused by sunlight. In this way, the motion detector avoids false triggers and ensures reliable detection of relevant objects.
