Abstract: A device and method, which progressively and sequentially increases the volume of the alarm signal upon the initiation of the alarm, is provided. The disclosed device includes a multiple voltage-controlled oscillator, at least two dual-input positive-NAND gates, a shift register and a plurality of transistors and resistors, which are configured to sequentially include the resistors into the alarm circuit. The method includes sequentially and progressively increasing the volume of an initiated audio alarm signal by sequentially including one of the plurality of resistors into the alarm circuit to vary the volume of the alarm signal emanating from an alarm speaker. The resistors are included into the alarm circuit by sequentially switching on the corresponding one of the plurality of transistors. The transistors are switched on in response to outputs received from a shift register, which is shifted in response to an output received from a first NAND gate.
