Bosch DS150I

The Bosch DS150I is a request-to-exit (REX) motion detector designed to integrate with access control and door control systems in commercial buildings, providing automatic exit detection when personnel approach secured doorways. The detector monitors a 2.4 x 3.0 meter (8 x 10 feet) coverage area using passive infrared motion sensing technology, with adjustable relay latch time up to 60 seconds. When motion is detected in the monitored zone, the device triggers its dual Form C relay contacts to command door strike release or similar access control functions, supporting both fail-safe and fail-secure programming modes for flexible security integration.
