1. A warning system capable of providing verbal instructions in cases of emergency situations, comprising fire or smoke hazards, said warning system having an alarm system for guiding individuals caught in emergency situations away from hazards, said alarm system comprising:

  • a. a smoke detector connected to a first point of a powered source and to a second point of said powered source;

    b. a printed circuit connected to the smoke detector;

    c. a smoke detector output relay connected to the printed circuit from a side which is easily exposable to smoke upon commencement of and during emergency situations;

    d. a recording switch connected to the printed circuit at a point that is easily reachable by an individual for changing verbal instructions of the alarm system used for emergency situations;

    e. a microphone connected to the printed circuit;

    f. a digital recording and a play back device located close to the recording switch and to the microphone;

    g. a timer/pulse generator located adjacent to the digital recording and the play back device;

    h. a pulse counter located proximate to the timer/pulse generator in order to minimize time delay between sending of pulses by the timer/pulse generator and receipt of pulses by the pulse counter;

    i. an alarm tone generator for generating alarm tones and being located proximate to the pulse counter;

    j. an amplifier located adjacent to the timer/pulse generator axial to the digital recording and the play back device such that controlled output of the digital recording and the play back device and of the alarm tone generator is sent to the amplifier; and

    k. a number of speakers which are capable of emitting clear, high-pitched loud acoustical signals and verbal messages, said number of speakers located adjacent to the amplifier such that the output of the amplifier is sent to the number of speakers;

    wherein sound waves produced by the number of speakers are intended to be louder than high ambient sound levels that surround individuals in emergency situations.
