"The serious losses in life and property resulting from fires causes me deep concern. I am sure that such unnecessary waste can be reduced. The substantial progress made in this country during the last 40 years convinces me that the means are available for limiting this unnecessary destruction," said President Harry S. Truman at his conference on fire prevention in 1947. Sixty-seven years later, fires still result in large loss of life, and people still ignore fire alarm signals. We have made progress in controlling fire. At least we know how to do so with automatic sprinklers. However, when people ignore a fire alarm signal, it poses a substantial threat. People typically disregard fire alarms as false alarms. So, why don't we have false-alarm-free fire alarm systems? It's because we still have systems that are poorly designed and installed.
