L-DALI-BM2 Pushbutton Coupler

The LDALI-BM2 pushbutton coupler

The LDALI-BM2 pushbutton coupler integrates customary light pushbuttons and switches into a DALI channel. With the CEA-709/DALI or BACnet/DALI controllers, a compact control module with 4 free programmable switching inputs is available. When the pushbutton is pressed, DALI commands are sent to a DALI group within the DALI channel or even across DALI bus limits to the corresponding building network (via L-DALI controller)2
Each input receives its own functions independent of the switching behavior (short or long push of a button, toggle, button, or switch mode). The following functions are available:
Dim up, dim down,
On with last dimming value,
Scene recall: 1–15,
Dim to a specified value in %,
Color temperature warmer/colder,
Active auto mode.
In the mode toggle, the function is carried out depending on the lighting status (toggle switch).
The module LDALI-BM1 is directly connected to a DALI channel and also supplied with energy by that channel.
