Keri Systems NXT-4DNE 4-Door Controller, No Enclosure

Designed for modern IT-driven security environments, the Keri Systems NXT-4DNE 4-Door Controller delivers fast, cost-effective access control deployment for commercial and enterprise sites. This access control panel features built-in Ethernet and a proprietary MAC for reliable hardware discovery and true 1-button autoconfiguration, cutting installation time and reducing on-site cabling costs. As a 4-door controller with support for up to four NXT-4X4 I/O expansion boards via RS-485, it scales to growing access needs while keeping local logic at the controller to limit network traffic and preserve bandwidth for other security and surveillance systems. Compatible with standard Wiegand readers as well as Keri’s NXT and MS proximity readers (reader supervision supported), the NXT-4DNE integrates seamlessly with Doors NetXtreme client/server software for centralized monitoring, logging and system management.
