Keri Systems NXT-RM3 Reader Interface Module for Wiegand and MS Compatibility

Optimize access control deployments with the Keri Systems NXT-RM3 reader interface module — a plug-on reader interface designed to reduce wiring, speed installations and improve system reliability. This reader interface module supports industry-standard Wiegand output and Keri MS Series proximity readers, making it ideal for mixed environments and legacy system migrations. The NXT-RM3 mounts directly to NXT controllers or to NXT-4X4 and GIOX I/O expansion modules, allowing you to move reader terminations closer to the door and run only four wires back to centrally located controllers. Multi-format adjustment and secure plug-on connections simplify field setup and reduce commissioning time, while the module’s rugged build delivers consistent performance for access control, security and surveillance applications. Use the NXT-RM3 to cut installation time, lower cabling expenses, and maintain compatibility with existing credentials and controllers. Contact your reseller or add the NXT-RM3 to your next security project to streamline monitoring and entry control across facilities.
