Keri Systems NXT-2D Legacy Door NXT Controller for 2-Door or Single Door Access/Egress with Enclosure

Optimize site security and reduce installation time with the Keri Systems NXT-2D legacy door controller — a 2-door/4-reader access control panel engineered for modern IT networks. Built-in Ethernet/TCP-IP connectivity eliminates costly adapters and lets you leverage existing LAN/WAN or a dedicated CAT-5/6 backbone, cutting cabling expenses while preserving valuable bandwidth through on-board decision-making.

The NXT-2D supports up to 48,000 cardholders and a 10,000-event buffer, providing scalable access control and reliable event monitoring for offices, campuses, and secure facilities. Installers benefit from a locking metal enclosure, quick-disconnect connectors, embedded MAC addressing for one-button auto-configuration, and flexible I/O expansion via RS-485 NXT-4X boards. Compatible with Keri’s Doors.NET software and multiple reader types (Wiegand, NXT Prox, MS Series), the controller integrates smoothly into security, surveillance, and access management solutions.
