Abstract: Safety systems and methods for elevator systems include an elevator car configured to travel along an elevator shaft, a pit at a bottom of the elevator shaft, and a governor having an energizable actuator configured to be continuously energized from a time of activation to a time of reset, the governor configured to stop downward movement of the elevator car along the elevator shaft after the time of activation until the time of reset, with energizing of the energizable actuator being initiated from an electrical trigger mechanism proximate the pit of the elevator shaft.
