Description • hager presence detectors are specially suited for applications like office cabins, conference rooms, cafeteria, classrooms etc. Features & benefits • double lens technology used in hager pirs offers exceptional standards in infrared detection • micro movements are sufficient to switch on and maintain lights on • adjustable head orientation allows adapting the detection zone according to rooms configuration • lights are inhibited from being switched on if natural light is sufficient in the room • direct control of a light load or used as a slave for detection area enlargement • lux level and on delay setting via potentiometers • test mode in order to set lux level and the detection area. Detection zone Covering a rectangular detection zone of 13 x 7m, the hager presence detectors represent an ideal solution for the offices, classrooms, toilets, corridors, markets and garages. In the event of assembly of two detectors in order to increase the range of detection, it is then recommended to respect a zone of covering of approximately a meter. Only two detectors will be thus necessary to cover a 25m length. A possibility of master/slave circuit exists for the communication of only one group of luminaries. The master presence detector ee812 or ee811 measures the lighting and the presence, then commutates and controls the electrical load. Auxiliary presence detectors ee810 detect only the presence and will announce this one to principal, which will carry out commutation and regulate the loads. Obstacles decreasing the range of the detector : • the partition walls, plants or racks, etc can limit the range of detection. Simulated movements : • the presence detectors capture fast modifications of temperature in the environment of the detector as being movements, for example at the time of or the stop starting of lowers with hot air, ventilators etc when the flow of air is directed directly on the lenses or of the objects near the zone of capture of the detector. • objects being heated slowly do not have a negative influence and Do not cause inopportune commutation. A side distance > 0.5m should however be respected. Proximity of the conduits of heating and the bodies of radiators. • luminaries switching on themselves and dying out near the zone of detection can simulate a displacement (p e.g of the lamps incandescence or halogen located at a distance < 1m). • objects moving such as mobile machines, robots, posters can also cause an inopportune detection.
