Keri Systems NXT-3R Mullion Mount NXT Proximity Reader for NXT Controllers, Access/Entry Version

Designed for tight spaces and high-demand sites, the Keri Systems NXT-3R mullion-mount proximity reader delivers secure, reliable access control where compact form factor matters. As a Keri Systems proximity reader, the NXT-3R mounts directly to metal window mullions or door frames without spacers, saving labor and hardware costs while preserving a low-profile aesthetic. Installers benefit from up to 1,000 ft (300 m) wiring distance over shielded CAT-5, reducing the need for repeaters and simplifying network cabling for IT and security teams. The reader provides up to a 4" read range, encrypted reader-to-card communications, and a supervised connection to NXT controllers for immediate notification of faults—ideal for access control, security, surveillance, and facility monitoring applications. Measuring under 4" high and drawing 14V DC, it supports compact retrofit projects and new installations alike.
