Johnson Controls Inc.
Network Controller
The S321-IP from Johnson Controls is an intelligent network controller capable of monitoring and controlling one or two fully-configured doors for small to large security installations. It uses standard TCIP/IP and has a browser-based graphical user interface. The controller can configure supervised four-state inputs and unsupervised two-state inputs. When interfacing to a single door, the unused points can be used as general purpose I/O points.
