Flexible architecture for larger systems

Couplers connect, extend and segment DALI systems and bring in external control. We help select the right devices to build a scalable, integrated architecture.

Common Applications

  • Multi-zone buildings
  • System expansion
  • Integration across systems
  • External control input

Common questions

  • What do couplers and control interfaces do?

    Couplers connect, extend or segment DALI systems and allow external control input, which enables larger, multi-zone architectures and integration with other technologies. They support flexible system design and easier expansion. The right devices depend on your system structure and integration needs. Share your layout and objectives and we can help select suitable couplers and interfaces.

  • When do I need to segment a DALI system?

    Segmenting helps when a system has many devices or several zones, improving manageability, performance and scalability. Couplers let you divide and connect segments so they work together. We help plan the segmentation and select suitable couplers for the structure, so the system stays stable and easier to commission and maintain.

  • Can couplers help integrate lighting with other systems?

    Yes. Couplers and control interfaces allow external control input and can support integration across zones or with other technologies. This helps lighting form part of a coordinated system. We support the lighting layer’s integration readiness rather than providing a full BMS. Share your integration objectives and we can advise on suitable devices.

Coupler Selection

The right couplers and interfaces let a DALI system scale, segment and integrate cleanly, supporting flexible, maintainable control architecture.

  • Segmentation

    System segmentation

    We help select couplers to divide larger systems into manageable, coordinated zones for stability and scalability.

  • Expansion

    Easier expansion

    Guidance on devices that let DALI systems extend and connect, so the system can grow without redesign.

  • Integration

    External control input

    Advice on interfaces that bring external control into the system and support integration across technologies.

  • Architecture

    Coherent system design

    Support planning a scalable, maintainable architecture using suitable couplers and interfaces.

Selecting couplers and interfaces

Couplers and control interfaces connect, extend and segment DALI systems and allow external control input, enabling flexible, scalable control architecture and integration across zones or technologies. The range includes push-button couplers and interface modules. The right devices depend on the system structure, scale and integration requirements.

  • Coordinated multi-zone control

Planning a multi-zone control system?

Coupler and interface selection depends on the system structure, scale and integration requirements. Share these details and we can help plan the architecture and select suitable devices, subject to confirming the full system.

Frequently asked questions

  • What information do you need to recommend couplers?

    The most useful details are the system structure and scale, the number of zones or segments, the devices involved, and any integration requirements. With this we can help select suitable couplers and interfaces for a scalable, coordinated architecture, and flag anything that needs checking. Sharing your layout and objectives helps us recommend the right devices.

  • How do couplers support system scalability?

    By connecting, extending and segmenting DALI systems, couplers let a system grow and be divided into manageable zones without redesigning it from scratch. This supports scalability and maintainability. We help plan where segmentation and extension are needed and select suitable devices, so the system can adapt as the building’s needs change.

  • Can couplers connect DALI to other control technologies?

    Control interfaces and couplers can allow external control input and support integration across technologies through DALI. This helps lighting coordinate with other systems. We support the lighting layer’s integration readiness rather than providing a full BMS. Sharing your systems and objectives lets us recommend suitable interfaces for a compatible integration.

  • Do you provide product data for couplers and interfaces?

    Yes. We can provide datasheets and technical documentation to support selection and system design. Tell us the system or requirement and we can supply the relevant data or help identify suitable couplers and interfaces from your architecture and integration needs, supporting a scalable, reliable control system.

  • Can you supply couplers alongside the rest of the system?

    Yes. We supply couplers and interfaces alongside DALI power supplies, dimmers, relays and Tridonic components, so you can source a complete control system from one place. We help ensure the devices work together within a coherent architecture, supporting flexible, reliable control across the installation.
