Shop request to exit devices for compatible security and access control systems. Also known as REX devices, these products signal when someone requests to exit through a controlled door. Choose from request-to-exit motion sensors, infrared detectors, touchless exit switches, and push-button devices for commercial and professional security installations.
Whether you are installing a new controlled entry or replacing an existing exit sensor, verify the device's operating method, relay configuration, power requirements, mounting style, and compatibility with the connected access control system.
Request to exit devices provide a signal to a compatible access control or door-control system when someone wants to leave through a controlled opening. Depending on the installation, the signal may initiate an authorized door-release sequence or another programmed response.
REX devices can use motion detection, infrared sensing, touchless activation, or a physical push button. The appropriate choice depends on the door hardware, controller, installation requirements, and intended exit method.
REX motion sensors detect movement within a configured area near a controlled door. When movement meets the sensor's detection criteria, the device sends a request-to-exit signal to compatible equipment.
Motion-based devices can support hands-free exit operation. Before choosing a sensor, review its detection range, adjustable sensing area, mounting position, output contacts, and compatibility with the door-control system.
Infrared request to exit sensors detect activity within a defined sensing area and provide an output to the connected system. Some models offer adjustable detection zones to help target the intended approach to a door.
Review the manufacturer's guidance for sensor positioning, detection coverage, environmental suitability, and installation height. Proper selection and placement are important to the intended operation of the door and the overall system.
Touchless exit switches allow users to request door release without physically pressing a button. Depending on the product, activation may use an infrared or other proximity-based sensing method, such as a hand-wave gesture.
Touchless devices are available in different faceplate styles, mounting configurations, and indicator options. Check the required activation distance, power supply, relay output, and environmental rating before selecting a model.
Request to exit push buttons provide a physical control for signaling an exit request. They are available in different sizes, faceplate materials, mounting formats, and labeling options.
When selecting a push button, check whether it uses momentary operation, its normally open or normally closed contact configuration, electrical ratings, and compatibility with the connected controller or door hardware.
Hands-free exit devices use a compatible sensor or touchless switch to initiate an exit request. These products may be suitable for facilities seeking sensor-activated door release rather than a conventional push-to-exit control.
Compare activation technology, sensing area, mounting requirements, relay configuration, and supported operating voltage. Confirm that the selected device is intended for the specific door-control application.
Commercial request to exit detectors are used with compatible access control and door-control equipment in offices, commercial buildings, and other controlled-entry environments. Certain models include adjustable detection zones, timers, tamper features, sounders, or multiple relay outputs.
For example, Kantech T.Rex devices include models with adjustable detection areas and additional door-monitoring or signaling features. Features vary by model, so verify the individual product specifications before purchasing.
Request-to-exit devices are typically selected as part of a complete controlled-door installation. The REX signal may be connected to an access control panel, door controller, or compatible door-release circuit, depending on the system design.
Confirm the required interface and operating sequence with the system documentation and the installer. A request-to-exit sensor is not necessarily a complete locking or door-release system, and the correct installation depends on compatible controllers, locking hardware, and applicable egress requirements.
REX stands for request to exit. It describes a signal or device used to indicate that someone wants to exit through a controlled door.
A REX sensor detects activity or presence using a supported sensing technology, while a request-to-exit button requires a physical press. Touchless switches provide another activation option.
No. Compatibility depends on the device's electrical ratings, output configuration, wiring, and the input requirements of the connected controller or door system.
Some installations support either option, but the choice depends on system compatibility, the intended activation method, installation requirements, and applicable egress rules.
Identify the existing model and confirm the operating voltage, relay contacts, mounting method, sensing technology, and controller compatibility. Also check whether the installation uses any additional timer, sounder, or door-monitoring functions.
