Keri Systems KB-2D-ADD-KIT Borealis KB Cloud Access Controller 2-Door Expansion Kit

Deploy cloud-hosted access control quickly and securely with the Keri Systems Borealis KB-2D-ADD-KIT 2-door expansion controller. Designed for integrators and facility managers, this access control panel kit delivers the operational benefits of cloud management while keeping critical decisions local to minimize bandwidth and improve uptime. The 2-door/2-reader design includes on-board TCP/IP connectivity—no additional network adapters required—and supports up to 10,000 cardholders with a 10,000-event buffer for comprehensive auditing and monitoring. Expand system I/O via RS-485 trunks to add NXT-4x4 boards as your site grows, enabling flexible integration with alarms, sensors, and surveillance systems. Enrollment is simplified with QR code provisioning through the Borealis Connect app, speeding on-site setup and reducing labor costs. Housed in a locking metal enclosure, the controller provides a secure, tamper-resistant solution for offices, campuses, healthcare facilities, and multi-site deployments. Choose the Borealis KB-2D-ADD-KIT to modernize access control, streamline security operations, and integrate with existing surveillance and monitoring infrastructure—contact us to specify this controller for your next project.
