Alarm Controls SREX-100 Infrared Motion Sensor for Request to Exit Applications, 28:-48", Built in Buzzer

For secure, reliable request-to-exit control, the Alarm Controls by ASSA ABLOY SREX-100 infrared motion sensor delivers focused, tamper-resistant detection where you need it most. Designed specifically for access control and exit monitoring, this motion sensor limits activation to the door-handle zone (28"–48") to stop cross-traffic and reduce nuisance triggers. Its active focused infrared technology cannot be fooled by objects placed under the door and is immune to thermal changes—ideal for high-traffic entryways, data centers, medical facilities, and secure office suites.

The SREX-100 operates on 12 or 24 VAC/VDC, offers a DPDT relay with 2A contacts, and includes inputs for request-to-exit, card reader/keypad, and door position switches. A built-in buzzer provides audible exit feedback and can be silenced when needed, while the adjustable 1–60 second time delay lets you fine-tune performance for your environment. UL 294 listing ensures it meets access control safety standards. Integrate this compact, black motion sensor into your access control and security surveillance systems to improve exit reliability and reduce false alarms—contact your supplier or add the SREX-100 to your next security specification.
