For system design. Indoor presence detection. When the KNX ARGUS presence sensor detects small movements in the room, data telegrams are sent via KNX to simultaneously control lighting, blinds, or heating, for example. In brightness-dependent motion detection for lighting control, the device continuously checks the brightness in the room. If there is sufficient natural light, the device turns off artificial light even if a person is present. The delay time is adjustable via ETS. With integrated bus coupler. Designed for wall mounting in a 60mm installation box, optimal use at 2.2m height. Equipped with anti-creep protection. KNX software functions: five motion/presence blocks, with up to four functions that can be triggered per block. Telegrams: 1 bit, 1 byte, 2 bytes. Normal operation, master, slave, monitoring, security pause, lock function. Two motion sensors: sensitivity and range can be set separately for each sensor. Learnable stair light duration. Brightness value can be detected via the internal and/or an external light sensor. Value correction. Detection angle of 180 degrees. Range of 8m to the sides, 12m forward (at a mounting height of 2.20m). Mounting height of 2.2m or 1.1m at half range. Time adjustable in steps from 1s to 8min (potentiometer) or adjustable from 1s to 255 hours (ETS). Number of levels: 6. Number of zones: 46. Number of motion sensors: 2, adjustable separately. Light sensor: internal light sensor continuously adjustable from approximately 10 to 2000 Lux (ETS), external light sensor via KNX. EU directives: Low Voltage Directive 2006/95/EC and EMC Directive 2004/108/EC. Delivery includes: bus connection terminal and mounting plate. With cover segments to limit the detection area. Material: painted thermoplastics. Color: Moccametallic.
