ABSTRACT:
The present invention relates to a system and method for the deactivation of an alarm system situated within a home or business environment by the use of a sound-activated wireless key device. This present invention describes a wireless key that “hears” a pulsing, warning tone, identifies the tone and automatically sends out a signal to disarm the alarm system thus allowing for the automatic hands-free deactivation of the alarm system. The invention comprises “listening” circuitry that is able to identify the sound of the audio warning, even when the invention is located within clothing or a handbag.
