I recently bought a Nuki Opener and I installed it on my intercom : Bitron Video 1407/010.
It is wired in 1+n configuration :
I connected the opener cables like described below :
- black and purple on 1
- blue on OP (the one bridged with 2)
- green on APP or in 2
The opener is able to open the door but it seems that it doesn’nt detect the ring.
To give you more details, I have a weird installation :
I have a separate ring buzzer which rings either when we push the button on the intercom street panel or when we push a button which is beside the door of my appartment.
I don’t really understand how this separate ring buzzer is connected to the intercom.
I opened the separate buzzer and there is only one wire coming which is looking very old and doesn’t look like an intercom wire.
I also opened the intercom street panel. I did’t understand all connections but I saw that the wire connected to my intercom button is purple and it is the same color than the one which is connected to the pin 2 in my handset.
