Radionix DS151I PIR Request-to-Exit Sensor

Detect motion in front of a controlled egress door and support a request-to-exit signal with the Radionix DS151I. This black-enclosure sensor uses PIR sensing for REX applications, where an occupant approaching an exit needs to initiate the door-release sequence without operating a manual device. Its stated coverage area is 2.4 m x 3 m (8 ft x 10 ft). The coverage footprint gives installers a concrete starting point for positioning the sensor over the approach area rather than the entire room. It suits access-controlled openings where the detection area must be aligned with the path through the doorway. PIR detection focuses the device on motion within its coverage zone, making placement, mounting height, and field orientation important parts of the installation design. DS151I is specified with a black enclosure for installations where the sensor is intended to visually blend with dark door frames, ceilings, or surrounding security hardware. Select it when the required REX detection zone is approximately 2.4 m by 3 m and the application calls for a black PIR request-to-exit sensor. Confirm the coverage area against the actual doorway approach path before final placement.
