Motion detector with a 360° detection area for ceiling mounting. It has a range of up to 24 m in diameter at a recommended mounting height of 3 m, making it suitable for small rooms and passageways with very little or no daylight. 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 and includes automatic light control. There is an additional pushbutton input. The standard version is designed as a surface-mounted device, with options for recessed ceiling mounting using accessories. The detection area can be extended by parallel connection, and targeted blanking of areas is possible with the enclosed lens mask.
