BRK is Ready for UL 217 8th Edition, Are You?
What is UL 217 8th Edition? An update to the UL standard for all manufacturers of smoke and combination smoke and carbon monoxide alarms. Alarms produced after June 30, 2024* must be compliant to the performance requirements as specified in the UL 217 8th edition Standard for Safety for Single and Multiple Station Smoke Alarms.
Fire Dynamics In The Home Have Changed
According to UL, newer synthetic materials in the home, more open layouts and lighter construction materials all burn hotter and faster. This research led the industry experts and UL to create new performance requirements for certain types of flammable material fires, such as polyurethane foam.
New Test Parameters

- Responsive to changes in home and finish materials
- More stringent nuisance alarm criteria
- More than 200 technical changes to the standard
Precision Detection Technology
Precision Detection is First Alert / BRK’s advanced sensing technology that will be used for all smoke and combination alarms in that comply with UL 217 8th edition revised smoke alarm standards. BRK’s Precision Detection alarms provide advanced and reliable fire protection to help protect what matters most.

Reduce Nuisance
According to the National Fire Protection Association (NFPA), nuisance alarms are a leading reason for disconnected smoke alarms. To enable manufacturers to produce more responsive alarms that do not cause nuisance alarms during cooking, UL conducted a research project to develop data on smoke characteristics during normal cooking events. This research led to new test requirements for nuisance alarm tests.
