Kantech Us T.REX-LT2-NL Request to Exit Detector

Product Description

The KANTECH US T.REX-LT2-NL is a request-to-exit (REX) detector designed for access control applications requiring passive infrared sensing with integrated timer and relay output logic. The unit includes two relay outputs and a tamper switch, giving installers the ability to monitor enclosure integrity while maintaining a clean, supervised exit detection circuit. It is typically mounted above a door on the secure side and connects to an access control panel as part of a compliant electric door hardware system. Licensed security or low-voltage electricians perform the installation in commercial and light-industrial environments.

This REX detector is used in commercial access control systems where a hands-free, passive infrared exit trigger is required at a controlled door. The two-relay configuration allows independent control of separate door hardware devices or panel inputs, and the built-in timer enables adjustable hold-open timing without external relay timers. It suits single-door and multi-door deployments in office buildings, data centers, healthcare facilities, and similar secured entry points. The tamper switch provides an alarm output if the enclosure is opened or removed from its mounting surface.

Key Features

• Passive infrared request-to-exit sensing for hands-free door release triggering
• Two relay outputs for independent control of door hardware or access panel inputs
• Integrated timer eliminates the need for a separate external relay timer module
• Tamper switch monitors enclosure integrity and generates a supervised alarm condition
• Compact form factor suited for above-door or wall-mount installation on the secure side

Compatibility

Designed as an OEM-style replacement or new-installation REX detector for commercial access control systems requiring a dual-relay passive infrared exit sensor with tamper monitoring.

Installation Notes

Installation should be performed by a licensed low-voltage technician or access control integrator familiar with NEC Class 2 wiring requirements. Power down the access control panel and all connected door hardware before wiring the relay outputs and tamper circuit. Mount the detector at the manufacturer-recommended height above the door on the secured side to ensure reliable detection coverage. Verify relay output polarity and timer settings match the door hardware and panel configuration before restoring power.
