High quality presence detector from Servodan in Denmark. The 41-750 is a mini control system built into one sensor. DALI light fittings can be individually addressed and grouped into four zones, zones can be automatically controlled based on movement and availability of natural light, manual control can be enabled with the use of momentary switches and there is even a built in relay for switching standard loads (HVAC, blackboards in class rooms etc), coverage can simply be extended by using slave sensors that are wired directly to the DALI bus (no mains connection required), excellent sensor for large areas, like classrooms, open plan offices, board rooms and etc.
The sensor uses a triple element detector arrangement for a large coverage pattern while being exceptionally good at detecting small movements (desktop motion).
