Battery Operated Smoke Alarm

Add reliable protection in minutes. The First Alert SMI100 Battery-Operated Smoke Alarm is easy to install - no wiring required. The front access battery compartment also makes for easy battery replacements and a low battery warning will advise when it's time to replace. Discourage unwanted removal of the battery or alarm using the optional locking features.

Convenient Test Feature

Use the simple test/silence button on the front of the smoke detector to check that it is operating properly and silence false alarms. An end-of-life warning will alert you when it’s time to replace the detector because alarms don't last forever. See user's manual for information on how and when to test and replace alarms.

Easy Installation

Battery-operated smoke alarm can be easily mounted on a wall or ceiling throughout your home to help provide an early warning to a fire emergency. The single test/silence button simplifies testing the alarm. An end-of-life warning will let you know when it’s time to replace the alarm all together. See user’s manual for information on how and when to test and replace 8th generation smoke alarms. Prevent unauthorized removal of the alarm by using the optional locking feature.

Upgrade to 8th Generation Alarms

First Alert's Precision Detection Advanced Sensing Technology meets the latest safety standards set by UL 217 8th Edition. This means this smoke alarm is better at distinguishing between harmless cooking smoke and real fires. Additionally, 8th edition smoke alarms can detect smoke from burning synthetic materials, which are common in modern homes. This translates to fewer bothersome false alarms and a crucial early warning in case of a fire emergency.

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.
