Description
Overview
The LNL-4420 controller enables Ethernet connection directly from an entry location to the OnGuard server. The controller is scalable for most access control applications. In addition, other I/O and reader interface modules can be added to the controller’s two downstream ports, further expanding its capabilities. In the event of communication loss, the LNL-4420 controller can maintain most of its local functionality until the server connection is restored.
