Duorail™ System

  1. Is your low voltage DUORAIL™ system UL listed?
    Yes. It is UL & CUL listed for both the United States and Canada
     
  2. What components do I need to build a complete DUORAIL™ system?
    The basic components of a DUORAIL™ system are as follows:

    - Transformer
    - Power feed
    - Rail / Connectors
    - Rail support
    - Fixtures / Pendants
    - DUORAIL™ QUICK CONNECT™  Adapters
     
  3. What is the capacity of DUORAIL™?
    DUORAIL™ is rated at 25 amps: this means a 12 volt system has a maximum capacity of 2 x 300 watts. A 24-volt system has a maximum capacity of 2 x 600 watts.
     
  4. What if I need more wattage?
    You can use more than one power feed. Utilizing multiple power feeds between non-conductive I-connectors (I-DEC) gives you the appearance of one continuous run. Each section can then have up to 2 x 300W at 12V (or 2 x 600W at 24V).
     
  5. How long can I make a DUORAIL™ system?
    There are two considerations, capacity and voltage drop. In terms of capacity, it can have as many power feeds as is necessary to support the wattage. In terms of voltage it is limited to the distance power can travel through the rail.

     
  6. When powering from a remote transformer, what gauge of wire should I use between the transformer and the power feed?
    A minimum 10-AWG wire should be used. Heavier gauge wire is needed if the transformer is not within close proximity to the power feed. See page 169 in WAC Lighting’s main catalog for the corresponding voltage drop chart.
     
  7. When I installed a dimmer on my DUORAIL™ System, the transformer started to buzz, what can I do about it?
    Check that you have the correct dimmer switch for the type of transformer you are using (i.e. electronic low voltage dimmer with a electronic transformer, low voltage magnetic dimmer with a magnetic transformer). An integral de-buzzing coil is included with all of our surface mounted magnetic transformers. However an additional in-line de-buzzing coil
    (model# LM-DBC12XXXXXX) between the dimmer and transformer is available to further reduce buzzing.
     
  8. How does the DUORAIL™ attach to the ceiling?
    The most common method is by using rigid standoffs, which are available in various lengths. We recommend 3 supports for an 8ft section of rail however a tightly curved rail may require more. We offer two variations of standoffs, one to fit on standard T-bar grid ceilings, and one to fit sloped ceilings. Additional cables are available 96” in length and are easily adjustable to shorter lengths. 
     
  9. Are the rigid standoffs field-cuttable?
    Yes. The standoffs may be easily cut to custom lengths. The standard sizes range from 3“ to 5 ¾” and additional rods are available up to 48”.
     
  10. Can I get longer standoffs?
    Longer standoffs are accomplished by using a coupler to join two rods together.
     
  11. Can I bend the DUORAIL™ in the field?
    Yes. We recommend using our bending machine (HM-BM).
     
  12. Can I field cut the DUORAIL™?
    Yes. The DUORAIL™ is field-cuttable
     
  13. Are all Quick Connect fixtures compatible with the DUORAIL™?
    Yes. You may connect any of our QUICK CONNECT™ pendants or fixtures to the DUORAIL™.
     
  14. What is the difference between using a surface mount transformer and a remote transformer?
    The surface mount transformers are mounted above the DUORAIL™, and can be seen on the surface of the ceiling. The remote transformer power feeds can be operated from further away, or in the ceiling, so they will not be seen.
     
  15. How is the DUORAIL™ System sustainable?
    The DUORAIL™™ utilizes LEDme® pendants and fixtures featuring state-of-the-art LED technology, as well as low voltage halogen elements.  The DUORAIL™™ System has a Five-Year Warranty and is Responsibly produced in WAC's clean, zero landfill manufacturing campus.
