Abstract
A shut-down and first-out annunciator device comprising sensor switches that change condition when a fault occurs. Logic and display circuits provide a digital readout indicative of a fault condition. Shut-down means are responsive to a shut-down signal produced by the logic circuit and produce a latching signal for the display. A first power supply powers all sections during normal operation and a second power supply powers the display and shut-down circuits after shut-down.
