In access control systems, a Request to Exit (REX) device is an essential component for safe and convenient egress. The RVN-REX and RVN-REX-T are both square-format push-to-exit buttons designed to work with magnetic locks or electric strikes. Mounted near the door’s interior, these buttons allow authorized personnel to exit without a key or credential, simply by pressing the button. Both models also feature a 12V LED backlight, ensuring clear visibility in low-light conditions.
The RVN-REX is the standard model. It provides a direct and immediate trigger to unlock the door when pressed, making it ideal for most common installations where no delay is necessary. It’s built for reliability and simplicity, with a clean design and universal compatibility with low-voltage access control systems.

The RVN-REX-T builds upon the same core functionality as the RVN-REX but adds an integrated adjustable timer module. This small internal circuit board allows installers to set a local unlock delay ranging from 1 to 60 seconds, making it ideal for situations where additional time is needed for the door to be held open—such as for ADA compliance, commercial entryways, or timed egress paths.
Choosing between the two depends on your installation needs. Use the RVN-REX when instant door release is preferred. Opt for the RVN-REX-T when timing flexibility is required, without needing to configure this behavior at the controller level. The timer is adjusted directly via a dial on the internal board, simplifying field configuration.
