What is a Request to Exit Device?

A REX device, short for Request to Exit, is a device in access control systems that provides a simple and convenient way to exit through access-controlled doors. A REX device is required for any door secured with a magnetic lock (mag lock). This ensures that individuals inside a secured area can exit in an emergency.

There are a few kinds of REX devices. One is the push button. Located near the exit, individuals must physically press the button to unlock the door. This manual operation is reliable and easy to use.

Another commonly used REX device is motion sensors, which detect movement and automatically activate the door to open when someone approaches it. This hands-free solution is well-suited to high-traffic areas where employees may have their hands occupied with belongings or equipment. It is also a more sanitary option than push buttons.

The last common solution is touchless buttons. These buttons detect proximity or hand gestures, allowing individuals to trigger the door's release without any physical contact. This is another sanitary option that is suitable for environments where cleanliness is of utmost importance.
