Description

The EER503 is a 360° flush-mounted ceiling presence and motion detector with an extended detection diameter of up to 20m. It features a normally open (NO) contact output for direct integration into standard switching circuits, making it well suited to large open-plan areas such as offices, warehouses, sports halls, and open retail spaces.
The combination of presence detection in the central zone and motion detection across the full detection area ensures reliable operation even with slow or minimal occupant movement. Adjustable time delay and sensitivity allow fine-tuning for specific room conditions.
Designed for flush-mounted ceiling installation and operating on 230V AC, the EER503 is RoHS compliant and works in tandem with the EER501 for installations requiring multiple zones of detection coverage.
