LCN Building Technology

Future-Proof Building Automation for Maximum Efficiency and Comfort

With the LCN bus system, you can easily automate all functions of a building. Thanks to its flexible expandability, LCN combines manual control with automated processes, offering seamless cross-discipline control. This ensures maximum comfort and cost savings through energy-efficient consumption optimization.

Innovative Technology: The LCN Bus System

LCN modules are intelligent, enabling autonomous communication, sensor evaluation, and actuator control—all without the need for a central computer. This independence provides a robust and future-proof foundation for your building automation and simplifies the installation process.

Simple Installation, Maximum Flexibility

Installation is straightforward: a simple standard NYM cable with an additional conductor is all that's needed. LCN modules do not require extra power supplies and are connected directly to the power cable, eliminating the need for separate wiring networks. This saves time, costs, and simplifies the installation process.

Scalable Solutions for Small and Large Projects

LCN is flexible enough to handle both small projects and large-scale developments. Each segment can contain up to 250 modules, and if needed, up to 120 segments can be linked, supporting up to 30,000 modules. This modular structure allows you to expand the system gradually based on your individual requirements.

Efficient Networking: Smart Communication Between Modules

LCN modules communicate via unique addresses, enabling efficient control of consumers through point-to-point or group addressing. This creates a "neural network" that becomes more intelligent and powerful as the number of modules increases—perfect for future automation tasks.

Tailored Solutions for Builders: Flexible Options for Every Requirement

LCN offers multiple solutions for every task. Whether you need an affordable basic solution for budget-conscious clients or a luxury variant for more demanding projects, LCN adapts. The system can also seamlessly integrate with conventional installation technology, giving builders the freedom to choose how much LCN technology they want to implement.

Building Automation of the Future

LCN is one of the world's leading building management systems. It recognizes authorized individuals, automatically opens doors, adjusts lighting and heating, waters gardens, and even switches doorbells to "silent mode" if needed. These features contribute to a more comfortable, safer, and energy-efficient lifestyle. Moreover, LCN can easily adapt to changing needs, making it a long-term investment.

Your Benefits with LCN:

  • Minimal installation effort due to flexible module architecture
  • Simple planning process with few regulations
  • Reliable bus topology with no data loss
  • Easy maintenance by electrical installers
  • High flexibility in control elements
  • Scalable to up to 30,000 modules
  • Flexible pricing for any budget
  • Intelligent control for increased safety and comfort
  • Energy efficiency for long-term cost savings

LCN is more than just a bus system—it's the key to a sustainable and efficient future in building automation. Contact us for a consultation and find the perfect solution for your project!
