What is the UL 217 8th Edition Smoke Alarm Update?

UL Solutions has updated its smoke alarm standards requiring smoke alarm manufacturers to meet new requirements by June 30th, 2024, to reduce nuisance alarms and detect smoke from synthetic materials. This update is known as UL 217 8th Edition and helps to improve fire protection for modern homes. As a leader and the most trusted brand in fire safety*, First Alert has introduced Precision Detection advanced sensing technology to meet new UL 217 8th Edition industry standards. First Alert Precision Detection Smoke Detectors and Combination Smoke and Carbon Monoxide Alarms are available for online purchase at the First Alert Store.

*First Alert Brand Trust Survey, March 2023 – Results are based on the responses of 1,043 adult homeowners, ages 25 and older, living in the United States who completed an online survey asking them to choose from six brands in the smoke, fire and carbon monoxide protection space.

Why Should I Use First Alert Precision Detection?
Our new advanced sensing technology complies with UL 217 8th Edition smoke alarm standards to reduce cooking nuisance alarms and provide an early warning in the event of a home fire emergency. Current smoke alarms will continue to provide protection until they reach their end of life. However, when it’s time to replace the smoke alarms in your home or you want to upgrade to the latest technology, look for Precision Detection to help identify compliant First Alert alarms. Smoke alarms should be replaced at least every 10 years.
What is the #1 Reason Why Smoke Alarms Are Disabled?
The #1 reason why people disable smoke alarms in their home is due to nuisance alarms caused by cooking or steam leaving them unprotected (NFPA). Almost 3 of every 5 home fire deaths result from fires with no smoke alarms or no working smoke alarms (NFPA) so it is important to install and maintain your home’s alarms. Installing 8th edition alarms equipped with Precision Detection and following proper placement of at least 15 ft. away from cooking appliances will help reduce nuisance alarms.
Why Is My Smoke Alarm Beeping?

Smoke alarms can beep for to the following reasons:

  • Low Battery: This is the most common cause. Most smoke detectors use a chirping sound (usually a single beep every 30-60 seconds) to warn you that the batteries are running low and need to be replaced. Don't wait until the alarm is silent - replace the batteries right away to ensure your smoke alarm continues to function properly.
  • End of Life: Smoke alarms don't last forever. If your smoke detector is beeping constantly or in a different pattern than the low battery chirp, it may be nearing the end of its intended lifespan and should be replaced altogether.
