Lenel LNL-X2220 Intelligent Dual Reader Controller

Overview

Advanced Access Control with LNL-X2220

The LNL-X2220 Intelligent Dual Reader Controller (IDRC) delivers powerful, flexible access control. It supports one or two doors and can connect directly to the OnGuard® system via Ethernet. Its modular design allows expansion with downstream I/O and reader interface modules.

Direct-to-Network Architecture

With the LNL-X2220, connect entry points directly to the OnGuard server over Ethernet. This setup keeps all the core security features of Lenel’s proven hardware while simplifying system architecture.

Uninterrupted Local Operation

Even during network outages, the LNL-X2220 ensures uninterrupted local functionality. It stores events and cardholder data locally, allowing smooth operation until the server connection is restored.
