ABSTRACT:
An adverse condition detector that allows the user to visually determine the type of adverse condition being detected. The adverse condition detector includes a sensor and a control unit coupled to the sensor. When the sensor detects an adverse condition above a selected level, the control unit generates an audible alarm signal and a visual alarm signal. The visual alarm signal simulates the type of adverse condition being detected. In one embodiment of the invention, the visual alarm signal includes a plurality of visual indicators operated in a random fashion to simulate the appearance of a flame.
