The NXT-4D Xtreme 4 Door Controller is built for today's IT environments. With all Ethernet functionality built directly into the controller, Keri's proprietary MAC address allows for reliable hardware discovery and true 1 button autoconfiguration.

To expand the system's capabilities, up to four companion 4 x 4 Input/Output boards (NXT-4X4) can be added - one to each of the controller's RS-485 trunks (busses).


  • Sophisticated Hardware Platform that reduces the total installed cost of access control

  • 100% Distributed Intelligence, Expandable 1 or 2 Doors at a Time
