Abstract
An annunciator comprises an annunciation and shutdown circuit having input terminals for a first power supply and input terminals for a second power supply. The first and second power supplies are connected to supply power in parallel with each other to the annunciation and shutdown circuit. A logic means responds to a fault signal causing the annunciation and shutdown circuit to switch to low power mode upon sensing that a fault signal has occurred.
