An elevator system (100) comprises an elevator car (101), an elevator controller (117), and a safety controller (121), connected to a plurality of safety devices (126a, 126b, 127, 129, 131, 138a, 138b, 140, 141) arranged to monitor the elevator system. The safety controller is configured to receive a signal in response to a change of state of any of the safety devices, and to determine a condition of the elevator system in response to the change of state of one or more of the safety devices. If the safety controller renders a determination that the elevator system is in a first condition, the safety controller causes an elevator brake to be deployed, preventing movement of the elevator car. If the safety controller renders a determination that the elevator system is in a second condition, the safety controller allows movement of the elevator car for a predetermined duration or until the elevator car has travelled a predetermined distance.
