The U.S. Fire Administration’s latest report, “Smart Smoke Alarm Using Linear Discriminant Analysis,” showed how new technology improves the performance of home smoke alarms.

The USFA teamed with the U.S. Consumer Product Safety Commission and Oak Ridge National Laboratory to make smoke detectors better and reduce “nuisance alarms.” The Smart Smoke Alarm uses Linear Discriminant Analysis (LDA) to differentiate between dangerous and benign conditions.

The USFA wrote on its website:

We’re researching ways to optimize modern smoke alarm sensors so that they can indicate the difference between dangerous home fires and nonhazardous conditions. This capability can reduce nuisance alarms that lead many people to disable smoke alarms – a potentially deadly mistake!

LDA uses temperature and carbon monoxide and other sensors to help distinguish between harmful and normal conditions. According to the USFA, this new technology will not be a significant price increase for consumers.
