For System M. Presence detection indoors. If the KNX ARGUS Presence detects small movements in the room, data telegrams are sent via KNX to control lighting, blinds or heating, for example. With brightness-dependent motion detection for lighting control, the device constantly checks the brightness in the room. If there is sufficient natural light, the device switches off the artificial light even if a person is present. The run-on time can be set via the ETS. With integrated bus coupler. For wall mounting in a 60 mm installation box, optimal use at 2.2 m. With creep-under protection. KNX software functions Five motion/presence blocks Up to four functions can be triggered per block. Telegrams 1 bit, 1 byte, 2 bytes. Normal operation, master, slave, monitoring, safety pause, blocking function. Two motion sensors Sensitivity and range can be set separately for each sensor. Learnable staircase lighting time. Actual brightness value Can be recorded via the internal and/or an external light sensor. Actual value correction. Detection angle 180 degrees. Range 8 m right/left, 12 m forwards (at a mounting height of 2.20 m). Mounting height 2.2 m or 1.1 m with half the range. Time can be set in steps from 1 s to 8 min (potentiometer) or adjustable from 1 s to 255 hours (ETS). Number of levels 6. Number of zones 46. Number of motion sensors 2, separately adjustable. Light sensor internal light sensor continuously adjustable from approx. 10 to 2000 lux (ETS), external light sensor via KNX. EC directives Low Voltage Directive 2006/95/EC and EMC Directive 2004/108/EC. Scope of delivery With bus connection terminal and support plate. With cover segments to limit the detection range. Material brilliant thermoplastic. Color glossy polar white.
