Hikvision doorbell connection pictures

Ok will try, no resistor was in the box, but a replacement arrives tomorrow.

Should the chime have the connections bridged this way? #0 and #3 have that thin wire bridging them.

Could I damage the doorbell messing about with it like this?

That wire is part of the circuit from the factory, leave it in. It completes the circuit when using instructions #3.
You could damage the doorbell if you hooked up the transformer directly to it.
 
So I know why it didn't work.

They sent me the KB6403 model which is the 12VDC version of the doorbell. I ordered the KB6003 which is the 24VAC!!

No wonder it doesn't work... tragic!

So now I've ordered the correct 12VDC 1A inl8ne supply for the replacement KB6403

Unbelivable.

I will keep you updated on how I do. Thank you so much for the excellent advice.
