Who invented the smoke detectors for the deaf?

The invention of smoke detectors for the deaf is credited to Dr. E. William H. Burch, who developed the first smoke alarm that used visual and tactile signals, such as flashing lights and vibrations, to alert individuals with hearing impairments. His innovation aimed to enhance safety and ensure that deaf individuals could respond to fire hazards effectively. The technology has since evolved, with various companies producing specialized smoke detectors for the deaf.
