A door exit button is used to unlock a door from the inside to allow someone to leave a secured area without needing a key or badge.
Request-to-Exit (REX): It signals an access control system to momentarily cut power to an electronic lock, such as a maglock or electric strike, so the door can be opened.
Emergency Egress: It provides a fast, manual way to exit during fires or power outages, ensuring building code and safety compliance.
Accessibility: It offers a simple, easy-to-use alternative for individuals who may struggle with heavy manual door handles.
Common Locations
Next to Doors: Typically mounted on the wall or door frame (jamb) right beside the exit.
Remote Desks: Sometimes installed under a receptionist's desk to allow them to remotely unlock a front door for visitors.
