Abstract
Abstract An audiovisual signaling device includes in electrical connection: (a) an auditory output portion which produces an auditory output and a corresponding low voltage oscillatory signal; (b) a converter portion which is responsive to and converts the low voltage oscillatory signal to a repetitively produced corresponding high voltage intermittent spike signal; (c) a visual output portion which produces a visual output; and (d) a portion responsive to the high voltage intermittent spike signal to repetitively activate the visual output.
