For system design. Motion detector for indoor use with creep-under protection. The sensor module detects moving heat sources (e.g. people) in an adjustable detection range and starts a stairwell lighting time. The sensor module has a light sensor with an adjustable brightness threshold so that the lighting is only switched on below a certain brightness threshold. Switchable presence function. Functions: Brightness-dependent stairwell lighting function, permanently on/off: -Electronic switching insert. -Relay switching insert. -Universal dimmer insert. -Control insert 1-10 V. -DALIi control insert. Brightness-dependent stairwell lighting function with channel 1, brightness-independent stairwell lighting function with channel 2, permanently on/off: -Electronic switching insert, 2-way. -Relay switching insert, 2-way. -Universal dimmer insert, 2-way. Detection range: 180 degrees. Control element: manual switch (0, auto, 1). Number of levels: 6. Number of zones: 46. Recommended installation height: 1.1 m. Range: 8 m right/left, 12 m forward. Sensitivity: continuously adjustable. Light sensor: continuously adjustable from approx. 10 to approx. 1000 lux. Time: continuously adjustable from approx. 10 s to approx. 30 min. To be completed with: Central station insert MEG5190-0000. Electronic switching insert MEG5151-0000. Electronic switching insert, 2-way MEG5152-0000. Relay switching insert MEG5161-0000.
