The C3 LON-Bus modules with Powerline coupler and, more recently, our innovative WA 40 Windows alarm annunciator, and the SISSYpro system with visualization in the control center, are used to record measured values and switching states, as well as to issue control commands.

Data is transmitted to the control center via existing 2-wire lines or via Powerline via the existing power lines. Alternatively, wireless GPRS packet data transmission is possible.

The LON bus technology is used with free bus topology and specific LON messages. Integrated telephone modems allow automatic telephone remote alarming of services.

It is also possible that UNITRO-Fleischmann, or a maintenance company, logs into the entire system via VPN in order to change parameters and to check the individual control modules for their functionality.
