Hello Nukiers,
Look here is a picture of my installation knowing that:
I live in a group of several buildings, all protected by common fence with intercom door
Each building has also its own intercom
Picture #1 is installation on my floor
Picture #2 is installation in my apartment.
How do you think I can plug Opener ?
Thank you community.
