Product Details

First Alert's Precision Detection advanced sensing technology complies with new industry standards to reduce cooking nuisance alarms and provides early warning in the event of a home fire emergency.

Through early warning interconnect, when one alarm sounds, all compatible alarms will sound

Battery backup provides continuous protection during power outages

Alarm indicator visually identifies the unit that initiated the alarm

Quick Connect Plug included allows for easy installation with no need to rewire

Best Review

Customers find the smoke detector easy to install with helpful instructions and appreciate that it works well as a replacement for Kidde models. The product is solidly built and customers consider it great value for money. However, the chirp frequency receives mixed reviews, with some customers reporting it chirps every 60 seconds. The battery power aspect also gets mixed feedback, with some customers noting it comes with a backup while others mention issues with low batteries.AI Generated from the text of customer reviews
