Ciao, ho visto questo pulsante nel mio appartamento vicino a Intercom. Credo che questo sia usato per la porta dell’appartamento e non per la porta comune nella hall. Ho provato a fare clic su di esso ma posso ancora aprire la porta dall’interno. La porta non è chiusa a chiave. A che serve?

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.
