Presence detectors for ceiling or wall installation

Presence detectors detect the slightest movements such as typing on a keyboard and ensure you're not left in the dark. Theben passive infrared (PIR) presence detectors are available in many different versions. Our ceiling mounted presence detectors have a square detection area and are therefore ideally suited for use in public buildings such as schools and universities. Wall-mounted presence detectors have a semicircular detection area, which reliably detects movements in hallways, corridors or storage areas. This provides presence dependent and energy-saving lighting control. Overview of Theben presence detectors:
