Abstract
A solid state alarm for a clothes dryer receives a line voltage signal prior to termination of the tumbling cycle to provide a series of pulses with decaying amplitudes driving a piezoelectric-type transducer. A timer terminating the series of pulses communicates with a pulse generating oscillator so as to eliminate partial pulsing at the conclusion of the alarm signal.
