L-DALI-BM1 Push-button Coupler

L-DALI-BM1 Push-button Coupler

 

The LDALI-BM1 button coupler integrates traditional light buttons and switches into a DALI channel. With CEA-709 / DALI or BACnet / DALI controllers, a compact control module with 4 programmable switching inputs is available. When the button is pressed, DALI commands are sent to a DALI group within the DALI channel or to another DALI channel available on the DALI controller to which the line is connected (via L-DALI controller).
Each input receives its own functions regardless of the switching behavior (short or long press of a button, button, button or switching mode). The following functions are available:

 

On with the last dimming value,
Scene recall: 1-15,
Dim to a specified value in %
Warmer / cooler color temperature,
Active auto mode.
In switching mode, the function is performed depending on the lighting state (push button switch).
The LDALI-BM1 module is connected directly to a DALI channel and also powered by that channel.
