KeriSystems NXT-2D/ 4D 2 & 4 Door Controller

The NXT-2D/ 4D  Xtreme 2 or 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 auto-configuration. Networking between NXT-2D controllers and/or its sister NXT-4D Xtreme 4 Door Controller also utilize peer to peer Ethernet standards. The NXT-2D/ 4D is designed to be extremely intelligent with little reliance on network traffic for decision making allowing it to be extremely thrifty with any network’s valuable bandwidth.

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). Customers can choose between Keri’s new line of highly secure, 4-wire NXT Proximity Readers with reader supervision, and any reader with a standard Wiegand output or Keri’s MS Series Proximity Readers via the NXT-RM Reader Interface Module. To manage the system, Doors NetXtreme software has much of the same look and feel as Keri’s acclaimed original DoorsTM software, but with the added functionality of Client/Server architecture.
