Installation notes

  • During detailed design, deliver circuit schedule, address schedule, and scene schedule together with construction drawings
  • Integrated hosts are recommended for centralized installation in low-voltage cabinets or equipment rooms with space reserved for cooling and maintenance
  • Wire per project drawing; signed projects use factory shipment drawings
  • After power-on, commission with terminal modules and panels: card power, lighting, and scenes, item-by-item acceptance

Companion hotel smart switch panels

RCU hosts coordinate guestroom loads with smart switch and scene panels on RS485 or wireless bus.
