How we use BEG Luxomat

PD9-KNX series: the PD9-KNX-DX is BEG's most popular ceiling-mounted presence detector. PIR passive infrared detection (360° horizontal, 10m diameter at 2.5m mounting height) with integrated daylight measurement (photocell, 1-1000 lux range). Native KNX TP BCU (bus coupling unit) built into the sensor housing — no external module needed. ETS6 application: download from KNX Product Database (KNX.org) or directly from beg-luxomat.com. KNX objects: movement detection (1-bit DPT 1.002), absence detection (1-bit DPT 1.002, delayed), daylight value (2-byte float DPT 9.001, lux), constant-light setpoint output (2-byte float, for DALI/1-10V dimmer), orientation light (1-bit, dim to 10% when room empty but occupied building). The PD9-KNX-DX dimensions are identical to a standard 100mm ceiling luminaire knockout — can be installed flush in a suspended ceiling tile without tools. PD4-KNX corridor sensor: designed for corridors and stairwells where ceiling height reaches 3-5m. PIR detection: 120° horizontal, 1.0m wide × 12m long detection field at 3m mounting height — optimised for linear corridor detection rather than area coverage. Dual-action output: movement detection 1-bit AND a separate reduced-level output (1-bit) — corridor lighting steps from 10% orientation to 100% occupied level on detection, back to 10% on absence (without full off, maintaining egress illumination). ETS6 programming: standard 4-step corridor logic programmed natively in the PD4-KNX ETS6 application, without additional ETS6 logic blocks — reduces commissioning time significantly. LC-Click-KNX constant-light controller: for installations requiring constant illuminance (office EN 12464-1: 500 lux working plane), the LC-Click-KNX adds a separate KNX constant-light controller to any DALI or 1-10V luminaire circuit. The LC-Click clips to the DALI line inside the luminaire junction box, measures actual lux from a remote photocell, and sends DALI or KNX output signals to maintain target illuminance regardless of daylight contribution. LC-Click eliminates the need for KNX HVAC constant-light setpoint logic in ETS6 — the function runs locally within the LC-Click device, sending only trimmed DALI level commands. KNX group address output: actual measured lux (DPT 9.001) for BMS energy monitoring, and a 'setpoint reached' flag (DPT 1.001) for fault alarm if daylight gain cannot maintain setpoint (window obstructed, sensor dirty). Outdoor and weatherproof sensors: BEG PD2-KNX: IP44 wall-mounted PIR for outdoor security lighting (140° horizontal, 12m range at 2m mounting height), KNX TP connection via watertight cable gland, -25°C to +55°C operating temperature. Suitable for villa gate pillars, building facade soffit mounting. ETS6 application: same pattern as indoor PD9-KNX but with outdoor-specific time delay options (10-60 minutes holdoff). PD2-KNX + DALI outdoor LED driver (e.g., Tridonic CLE 60W Compact): KNX PIR event → DALI ON command via KNX actuator → outdoor flood at 100% for 5 minutes, then dim to 30% orientation if building still occupied (ETS6 timer logic), full OFF at 30min absence.

All BEG sensors are native KNX TP devices, programmed in ETS6. Movement detection (DPT 1.002), absence detection, daylight value (DPT 9.001), and constant-light trim output (DPT 5.001) all communicate directly on KNX bus without bridges. BEG sensors integrate with any KNX actuator brand via group addresses — no vendor lock-in. Typical wiring: 2-wire YCYM KNX cable from panel bus bar to ceiling junction box, then short stub to sensor BCU terminal.
