A monitoring system for controlling self-testing of a traction elevator includes a self-testing process module in communication with a three-phase AC back-up battery power supply. The self-testing process module includes a processor configured to initiate and control a series of steps for performing measurements of the three-phase AC back-up battery power supply, including measurements of the battery supply during a simulated emergency situation (“rescue/evacuation”). The processor is programmed to initiate testing on a defined schedule and transmit test results to a maintenance system (including remotely-located systems) on a routine basis. The monitoring system also includes a display unit providing visual information regarding the status of self-testing processes and their results and a communications unit for transmitting test results to a remote maintenance controller.
