A visual alarm device monitors the condition of a control and indication circuit and gives a distinct visual alarm upon detection of an abnormal condition in the monitored circuit. The device uses the indicator lights of the monitored circuit itself to give the visual alarm. The alarm device interconnects with the monitored circuit locally requiring no new cabling and remains in a passive state until an abnormal condition is detected. When the monitored circuit is rendered inoperative by a thermal overload trip, the alarm device becomes active to flash the indicator lights to provide a distinct visual alarm. Included in the device is a test switch, an appropriate voltage converter, an oscillator, and a power indication light.
