Elevator systems and methods are provided. The systems include a traveling component movable along a guide rail within an elevator shaft, an elevator machine operably connected to the traveling component and including a machine brake, and an overspeed safety system. The overspeed safety system includes a safety brake and an electromechanical actuator, the brake engageable with the guide rail. A safety system controller operably connects to the electromechanical actuator and triggers the electromechanical actuator due to at least a detected triggering event. A temporary power supply is operably connected to the overspeed safety system to provide power in the event of a power failure.
