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.
- 48,000 Cardholders, 10,000 Event Buffer
- On-board TCP/IP Connectivity
- Re-assignable Inputs and Outputs
- 128 Bit Encryption
- Both 2-door and 4-door Versions Available
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.

The Amazon Key does not interface to Keri products in a way that allows the Building Owner or Manager to maintain complete control over their system, nor does it provide any tracking information on when the Amazon Key was used to open a door.
The addition of the Amazon Key to a site introduces a security degradation beyond the control of Keri’s access control system. Neither Keri nor Amazon provides any documentation on how an installer would integrate the Amazon Key with Keri’s access control system. Because of this, Keri has strong concerns about the knowledge of the Amazon Key installers as evidenced by the damage Amazon Key installers have caused to Keri controllers and installations at multiple sites.
Any Keri controller failure caused by the installation of an Amazon Key device is cause for voiding the controller warranty. Keri cannot be held responsible for any security lapses created by the use of the Amazon Key
