Door control unit for an elevator system, method of maintaining an elevator system, and maintenance device for maintaining an elevator system

Abstract

A door control unit for an elevator system includes a first communication module and a second communication module. The first communication module communicatively connects the door control unit with a data network of the elevator system. The door control unit is communicatively connectable, via the data network, with a car control unit of the elevator system. The second communication module is activated in response to a maintenance indicator signal. When activated, the second communication module operates as an access point of a wireless maintenance network wirelessly communicatively connecting the door control unit with a maintenance device via the wireless maintenance network.
