Lenel LNL-X2220 Intelligent Dual Reader Controller (IDRC) — a single-board solution for interfacing one or two doors to an OnGuard® system. Native Ethernet lets the controller connect directly from the entry location to the OnGuard server, and additional I/O and reader interface modules can be added on the downstream port to expand its capabilities.
In the event of communication loss, the LNL-X2220 allows nearly all local functionality to continue unimpaired until the server connection is restored.
