The Excelsior (EXL-REX) Request-to-Exit (REX) detector is a passive infrared (PIR) motion sensor designed to detect human presence near secure doors, unlocking them automatically for egress. It is a reliable, often programmable, hands-free solution meant to replace or supplement exit buttons, commonly featuring adjustable detection zones and, in some models, built-in sounders.
Key Features and Functions
Technology: Uses passive infrared technology to detect motion, often featuring digital signal processing to prevent false triggers.
Automatic Operation: Automatically unlocks or shunts doors upon detecting someone walking towards the exit.
Adjustment: Offers adjustable detection zones (often with X-Y targeting) to minimize accidental activation.
Programmable: Models are typically fully programmable for varied applications.
Safety & Security: Integrates with access control systems for both security (preventing unauthorized entry) and life safety (ensuring free egress).
