Effective June 2021, UL LLC will no longer list smoke alarms that are unable to distinguish between non-fire sources of smoke and smoke from an actual fire. Nuisance alarms sound when the alarm is set off by non-fire incidents like cooking, and are the #1 reason why people disconnect their smoke alarms.
Without working smoke alarms, people are more than twice as likely to die in a home fire.
With smarter smoke alarms available, the hope is that fewer people will disable their smoke alarms, leading to fewer fire deaths. It also has the potential to reduce the number of nuisance alarm calls that fire departments have to respond to each year.
