ELEVATOR SYSTEMS

An elevator system includes an elevator car moveable between a plurality of landings and a brake configured to stop the elevator car from moving within the elevator shaft. The system includes a safety controller and at least one safety device. The safety controller monitors for a change in status of the at least one safety device. Upon detection of a change to a new status, the safety controller evaluates whether the new status is a first status corresponding to an emergency situation or a second status corresponding to a non-critical change. The safety controller is further configured to apply the brake immediately to stop the elevator car when the new status is a first status or allow the elevator car to move to a landing when the new status is a second status.
