Lenel LNL-8000 Star Multiplexer for OnGuard® Access Control Systems

The Lenel LNL-TS-8000 Star Multiplexer is a communication expansion module designed to extend and optimize LenelS2 OnGuard® access control systems. Engineered for enterprise and government-grade deployments, the LNL-TS-8000 enables star topology configurations from an Intelligent System Controller (ISC) or host, improving wiring efficiency, scalability, and overall system reliability.

Ideal for distributed security installations, this module supports RS-232 or RS-485 upstream communication and provides multiple downstream RS-485 ports for connecting Lenel interface modules, reader boards, and I/O devices. The LNL-TS-8000 reduces installation complexity while maintaining high-performance communication across large facilities.

Why Choose the LNL-8000?

Traditional daisy-chain configurations can create communication bottlenecks or single points of failure. The LNL-8000 Star Multiplexer improves system architecture by allowing centralized distribution to multiple RS-485 branches, enhancing fault isolation and simplifying troubleshooting.

• Supports enterprise-scale access control deployments
• Enables star topology expansion
• Reduces wiring complexity
• Improves communication reliability
• Seamless integration with Lenel OnGuard® systems

Key Features

• RS-232 or RS-485 upstream communication
• RS-485 downstream expansion ports
• Supports up to eight (8) downstream devices per port
• Jumper-selectable 2-wire or 4-wire RS-485 configuration
• LED indicators for heartbeat and communication status
• Compact form factor for panel enclosures
• UL 294 and UL 1076 listed

Ideal Applications

The LNL-8000 is commonly deployed in:

• Corporate enterprise campuses
• Higher education institutions
• Healthcare facilities
• Government and municipal buildings
• Critical infrastructure environments
• Industrial and manufacturing sites

It is particularly beneficial in large facilities where multiple access control modules must communicate reliably over extended distances.

Technical Specifications

Scalable Expansion for Enterprise Access Control
