Hallo, ich habe diesen Knopf in meiner Wohnung in der Nähe der Gegensprechanlage gesehen. Ich glaube, dies wird für die Wohnungstür und nicht für die gemeinsame Tür in der Lobby verwendet. Ich habe versucht, darauf zu klicken, aber ich kann die Tür immer noch von innen öffnen. Die Tür ist nicht verschlossen. Was nutzt es?

It’s to shut a fire or smoke protection door. In case of a fire close it
Maybe the apartment door used to have an electronic component to open and close via button press for accessibility (ie wheelchair) but it was removed during refurbishment and they just didn’t take out the inside button? Typically those buttons both close and open the door though, so just a guess.
It’s for Tür schließen, it schließes the Tür.
This button is connected to an electrically controlled door closer. In case of fire, the door must close automatically, but if that doesn’t happen one can press such a button to manually trigger the closing of the door.
Fire/smoke Protection doors Are Held open magnetically. If you want to close it (when there is no fire or the alarm didn’t deactivate the magnets) press this button
