A circuit interrupting device including one or more line terminals for connecting to an external power supply, one or more load terminals for connecting to an external load, one or more contacts electrically connecting one or more line terminals to one or more load terminals, and an auto-monitoring circuit. The auto-monitoring circuit configured to monitor one or more signals to determine an operating state of said circuit interrupting device, output a first signal having a first voltage level based on the operating state, wherein the first voltage level is greater than zero volts, and output a second signal having a second voltage level based on the operating state, wherein the second voltage level is greater than the first voltage level.
