Keri Standard NXT 2/4 Door Controllers (Legacy)

This product is now Obsolete, available for legacy installations only

The NXT-2/4D Controller is built for today’s IT environments. By using an existing TCP/IP network, controller cabling costs can be eliminated. Or, if building a new network, they can be reduced up to 50% over traditional hard-wired access systems by using inexpensive, shielded CAT-5 cable. The NXT-2/4D is designed to be extremely intelligent with little reliance on network traffic for decision making, allowing it to be thrifty with any network’s valuable bandwidth. With Ethernet functionality built directly into the controller. Keri’s proprietary MAC addressing scheme allows for reliable hardware discovery and true one-button autoconfiguration.

To expand the system’s capabilities, companion 4X4 Input/Output boards (NXT-4X4) can be added – one to each of the controller’s RS-485 buses. Customers can choose between Keri’s line of highly secure, 4-wire NXT Series Proximity Readers with reader supervision that also provide In/Out reading capability at each bus, or, when using a Reader Interface Module (NXT-RM3 or NXT-WIPLUS) either a standard Wiegand output reader or Keri’s MS Series Proximity Reader. Doors.NET software has much of the same look and feel as Keri’s acclaimed original DoorsTM software, but with the added functionality of a Client/Server architecture.
