Lenel Intelligent System Controller, LNL-M3300

The Lenel LNL-M3300 Intelligent System Controller (ISC) is a powerful, enterprise-grade access control panel designed to serve as the core decision-making engine for modern security systems. Built for use with the OnGuard® platform, the LNL-M3300 delivers reliable, scalable, and secure control for complex access control environments.

Engineered with a high-performance 32-bit processor and native Ethernet connectivity, the LNL-M3300 enables fast, secure communication with host systems using single- or dual-path network configurations. It supports up to 64 downstream devices—including input, output, and reader interface modules—allowing flexible system expansion across multiple doors and access points.

With robust onboard memory, the controller stores up to 500,000 cardholders and 500,000 events in non-volatile flash memory, ensuring uninterrupted operation even during network outages. Advanced access control capabilities include support for up to 32,000 access levels, 255 time zones, and 255 holiday schedules—making it ideal for enterprise, campus, and high-security facilities.

The LNL-M3300 prioritizes cybersecurity with AES 256-bit encryption, TLS 1.2/1.3 secure communications, and configurable data-at-rest encryption to protect sensitive credentials and system data. It also supports biometric templates, wireless lock integrations (including Aperio and Schlage), and up to 16 badge formats for maximum deployment flexibility.

Designed for reliability and ease of deployment, the controller features dual RS-485 ports for downstream device connectivity, flexible 12–24 VDC power input, and firmware stored in flash memory for seamless updates. Built-in event buffering and backup storage ensure continuous system performance even in the event of power or network interruptions.
