ABSTRACT:
A wireless alarm system for generating alarm signals discernible to the hearing impaired. The system includes a detection unit having a smoke or carbon dioxide detector which generates a signal upon sensing the occurrence of smoke or carbon dioxide. A transmitter in the detector unit generates a wirelessly transmitted signal. A receiving unit worn on the body of a person includes a receiver and receives the signal generated by the transmitter. An alarm in the form of a vibrator is coupled with the receiver and generates a vibration discernible to the body of the user. A second alarm operates, or not, depending on whether the person acknowledges the vibrator.
