How is an electric lock and the floor pushbutton connected?

The following figure shows how to connect an electric lock and the floor pushbutton.

Notes Relais:
  • The relay keeps its state even in the case of loss of power. The device does not supply power to the connected device. The power supply for the electric door opener must be installed separately.
  •  When wiring an electric door opener directly to a door station, there is a risk that the electric door opener could be tampered by unauthorized third parties (e. g. by breaking the door station and short-circuiting the wiring of the door opener). Therefore, we generally recommend the use of a remote safety relay mounted indoors (e. g. DoorBird I/O Door Controller A1081) for wiring an electric door opener for a more secure installation in your home.  
Notes door opener / floor button:
  • Door opener button, max. 0 V DC / AC, 0 Ampere. These ports can be used to connect e.g. a door opener button inside the home. It will trigger the first bi-stable latching relay of the device (REL1, REL1).
  • Please make sure to add no voltage on these ports. Extra voltage may destroy the device immediately
