Abstract: Embodiments include a system, method and controller for tracking service mechanic status. The embodiments include a controller of an elevator system that is operably coupled to an elevator, wherein the controller is configured to control the elevator and detect a status of the elevator, and a processor operably coupled to the controller and a memory, wherein the memory is configured to store responder information, wherein the processor is configured to receive responder information from the memory and generate notification information based at least in part on the responder information. In addition, the embodiments include an interface unit for transmitting the notification information, and a notification unit operably coupled to the elevator and is configured to provide the notification information.
