15. A safety system for a building-based passenger transport system, the safety system comprising:
a safety unit receiving safety-relevant signals from components of the passenger transport system, and for triggering a safety measure in response to the signals;
an updating unit receiving updated software via an external interface, and transmitting the updated software to the safety unit via an internal interface;
wherein the updated software is received from a provider remote from the passenger transport system;
wherein the safety unit includes a first processor, a first volatile memory and a first non-volatile memory cooperating to store and run software and/or firmware that evaluates the signals;
wherein the updating unit includes a second processor, a second volatile memory and a second non-volatile memory cooperating to receive the updated software and transmit the updated software to the safety unit;
wherein the updating unit does not run the software and/or firmware stored in the safety unit and does not run the updated software; and
wherein the safety unit and the updating unit are accommodated in a common housing.
