Lenel S2 LNL-M2220 Intelligent Dual Reader Controller (LNL-M2220) 

The LNL-M2220 Intelligent Dual Reader Controller (IDRC) provides a single board solution for interfacing one or two doors to an OnGuard® system. In addition, other I/O and reader interface modules can be added on the controller’s downstream port to expand its capabilities. The LNL-M2220 controller revolutionizes access control system architecture by allowing Ethernet connection directly from an entry location to the OnGuard server, while still providing the security, functionality, and modularity of LenelS2's proven hardware platform. The LNL-M2220 controller is scalable for any access control application, from the most basic to the most sophisticated. In the event of communication loss, the LNL-M2220 controller allows nearly all local functionality to continue unimpaired until the server connection is restored.

Utilizing its native Ethernet communications and a secure 32-bit processor, the LNL-M2220 controller can communicate upstream to the host computer through its Ethernet port. The controller can store up to 250,000 cardholders in non-volatile flash memory, and supports selective download for larger cardholder databases. The downstream RS-485 two-wire port can be used to connect up to 32 devices (maximum 64 doors).

Two on-board reader ports support Data1/Data0, Clock/Data, Supervised and Unsupervised F2F, Biometric readers and the bi-directional RS-485 Open Supervised Device Protocol (OSDP) communications. Each LNL-M2220 controller supports up to sixteen different card formats. The LNL-M2220 controller includes eight inputs that support normally open, normally closed, supervised, and unsupervised circuits. In addition, four output relays support fail-safe or fail-secure operation.
