Patent number: 4742328Abstract: An alarm device capable of producing an audible as well as a visual alarm is disclosed. The alarm device comprises a gong, a DC motor of a commutator type and a hammer operatively connected to an output shaft of the motor for striking the gong. The alarm device further comprises a high-voltage generating circuit connected to the motor, a flash tube and an exciter circuit for the tube. When a DC power is supplied to the motor to strike the gong by the hammer, the high-voltage circuit generates a high voltage in accordance with a square-wave current which flows through the motor.
