Summary of Driver Options

For large rooms with many lights and multiple entrances, ATX LED's DR2 allows virtual 3-way control, operating up to 128 fixtures in sync while maintaining control over on/off, dimming, and CCT without delays. Beyond 16 DR2s, manual setup is required.

  • Each switch controls on/off, dimming, and CCT for the group
  • Instant color temperature adjustments without delay
  • Individual DR2 units remain addressable
  • Supports virtual 3-way across large zones
  • Non-DALI switches do not support virtual 3-way

The Rules

For part a) here are the rules:

  • Lights are 6 watts for all models except: Ceiling fan light (12W), 24 inch Bath Vanity (18W), 36 inch (24W).
  • Lights are either fixed CCT (lower cost, value product line) or tunable white (TW = Signature product line).
  • Fan motors are either 12W exhaust or 24W ceiling.
  • A switch loop is 1 switch, 4 TW or 8 fixed lights or fans.
  • Light switches (1 gang) options:
    • On/Off simple with 48v type LEDs, no dimming
    • Simple dimming with DR1 (single channel), small or large supply projects
    • Smart dimming with DR2 and Fixed LEDs (up to 10)
    • Smart dimming with DR2 and CCT LEDs
    • Multibutton pads
  • Ceiling fan motor control (1 gang): simple AL-WS-Carro or smart AL-WS-010v.
  • Exhaust fan motor control (1 gang): simple 120vac On/Off or smart AL-WS-M with 12v ATX Exhaust Fans.
  • Target 45 sq ft per 6W light, 180 sq ft is one switch.
  • Three-way switch is 1 gang (stairs, halls, large rooms) using AL-WS-M or AL-WS-8B.
  • Rooms with more than one DR2 have multiple loops.
  • Many loops can be combined into one large functional loop with unlimited lights, operating as 3-way using DR2 and Hub.
  • Under cabinet lights in kitchens are 1.5W per ft.
  • 2 or 3 pendant lights in kitchen island or other areas.
  • Vanity lights in bathrooms: 24 inch for dual sink, 24 or 36 inch for single sink.
  • Each entrance to a room, hall, or stair has at least a light on/off switch. If there is more than one egress, add a 3-way switch for each.
