Configuration Options

Standalone Wired or Wireless

The smart switches can be used on a standalone DALI-2 network, or a standalone wireless bluetooth network for small configurations and simple systems. Configure button functionality and status colour via bluetooth smart phone.


Wired 101 mode

The smart switch can be wired to a DALI-2 wired network as a DALI-2 switch. Button functionality and LED status colours are programmed through a central head end. 

Enabled after a 101 DALI-2 power supply has been connected to the DALI terminal and the device has not been added to a wireless 104 application controller.

Wireless control system as a switch input 104 mode

Similar to wired mode, but without cables. Connect to a wireless application controller and configure button functionality and LED status colours through a central head end.

104 mode is enabled after the device has been added to a 104 application controller such as zc-iot-fc.

Wireless control system as a bridge 104 + 101 mode

The same functionality as a the wireless system, however with the ability to connect wired DALI-2 devices to the switch and have those DALI-2 devices appear and be programmed on the wireless network.

104 + 101 bridge mode is enabled after the device has been added to a 104 controller and a 101 power supply has been connected to the DALI terminals.
