Motion detector with a 360° detection area for ceiling mounting. It has a range of up to 8 m in diameter with a recommended mounting height of 3 m, making it suitable for small rooms and passageways with very little or no daylight. It features a 10 A high power relay and zero-crossing switching, which prolongs the life of relays and lamps in electronic ballasts, such as fluorescent lights and LEDs, by gentle switching at zero-crossing. The factory setting allows for immediate operational readiness. It includes automatic light control, an additional pushbutton input, and remote control. The standard version is designed as a surface-mounted device, and the detection area can be extended by parallel connection. It also allows for targeted blanking of areas using the enclosed lens mask.
