This product has not been certified by an NRTL (UL, ETL, CSA or equivalent). Installation in USA projects may require a Field Evaluation by a recognized laboratory. Consult your local AHJ before specifying.
~ Low Voltage · SELV
This device operates on a Safety Extra Low Voltage circuit — such as the KNX 29V bus or a DALI 16V bus (NEC Class 2). When powered by an NRTL-listed power supply, many AHJs accept non-listed SELV devices. Verify with your local AHJ before specifying.

The Eelectron PD00E21KNX is the Corridor KNX presence and motion detector in white, designed for long, narrow spaces — hotel and hospital corridors, office hallways, warehouse aisles, underground car-park lanes — where a round-pattern sensor wastes most of its coverage. Two PIR sensing elements are arranged for a reach of roughly 40 m (131 ft) along the corridor and 5 m (16 ft) across at 2.5 m (8 ft) mounting height, and each element can be given its own behaviour in ETS, for example to switch luminaire groups ahead of the person walking.

An integrated illuminance sensor supports daylight-dependent and constant-light control, 5 independent presence channels serve lighting, HVAC and monitoring with different timings, and a rear connector provides 2 dry-contact inputs with the second switchable to an NTC probe for the on-board 2-stage PI thermostat. A plug-in port accepts the SM03E01/02/03 air-quality sensors. Mounting hardware for junction box and false ceiling is in the box; PD00E05ACC is the optional surface enclosure. The black version is PD00E21KNX-3.
