An elevator safety system (20) for an elevator system (2) with a self-diagnostic functionality includes at least two safety channels (22a, 22b), wherein each safety channel (22a, 22b) is configured for supplying a safety signal (23a, 23b) in case a safety issue has been detected. The elevator safety system (20) comprises a self-diagnostic evaluator (24), which is configured for receiving any safety signals (23a, 23b) supplied via the safety channels (22a, 22b); starting a timer (25) for measuring a predetermined period of time in case a safety signal (23a, 23b) is supplied on one of the safety channels (22a, 22b); and stopping any further operation of the elevator system (2) in case the received signal (23a, 23b) is still supplied after the predetermined period of time has expired.
