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.
