Connecting doorbell and gong tips

Hi guys,

I need your help, I think I'm too stupid to connect a doorbell and chime. I just don't understand the instructions for the chime. The wiring on the chime and the doorbell is also different. Both the transformer, chime, and doorbell are designed for v8-v12. The transformer is already installed in the control cabinet. Does anyone have an idea from afar how I should wire it? The green cable is for the doorbell outside. The grey one is for the flush-mounted chime inside.

It's resolved. The transformer in the control cabinet is not wired. Well then, I have to call the electrician.

But it is quite simple. The gong receives constant voltage and a wire for the impulse from the doorbell button. If a second doorbell button is present, it can even be connected additionally (with a separate sound?).

Or choose the melody by trying both and connect it where it feels more comfortable.

Be careful also with the transformer. Most 12V transformers are DC. But your chime needs 12V AC.

It says AC or DC voltage....
