Question about the door opening component #6

Closed Soldiiier closed 3 years ago

Soldiiier commented 3 years ago

Hello, I am interested in doing a similar task for the door opening component. Is the door open command sent via the data bus? how do you learn what the command/bits are, and are they cycled?

There is no data bus on the Fermax 4 + N Electronic Door Entry System. Therefore there are no commands/bits to learn and the door is opened by a relay contact that joins Wires 1 and 3 of the door station, as shown in the schematic here
