After many years of searching for the right smoke detector, I finally got one from the Blount County Fire Department. As a disabled veteran, one of my disabilities is not being able to hear high tones because of working on the flight deck of a U.S. aircraft carrier.
The Blount County Fire Department's Smoke Detector Team found one with a lower tone that could save my life in the case of a home fire. I salute them in their successful effort.
