DEVICE FOR CONNECTING A CONTROL DEVICE OF A PASSENGER-CONVEYING SYSTEM

A device for connecting a control device of a passenger transport installation to a communication unit for transmitting data to an entity remote from the passenger transport installation includes at least one detection unit detecting a first physical variable of the control device. The device further includes an evaluation unit generating a first electrical signal on the basis of the first physical variable detected. The device also includes a first interface connecting the device to the communication unit. The first electrical signal is transmitted to the communication unit via the first interface. The detection unit detects at least one of an electrical resistance, an electrical voltage, a visual state an acoustic signal of the control device as the first physical variable.
