what’s the difference between those two devices?
Obviously the /NS has no physical Button. Does this mean I can use my own Doorbell-PushButton or does this mean I have to use the SUB Modul DS-KD-DD?

I don't have your answer but this is what I have found, that is if you have not already viewed them. Looks like you will need an input module with the /NS
