About This Product

The USI Hardwired Smoke Alarm with Replaceable Battery Backup provides advanced protection for your home. Featuring Sensing Plus Multi-Criteria Detection, it accurately detects both slow-burning and fast-flaming fires for early warning and rapid response. This hardwired alarm can interconnect with other compatible alarms in your home, providing comprehensive coverage. A replaceable 9-Volt battery ensures continuous protection during power outages, and an End-of-Life alert signals when it’s time to replace the alarm after 10 years. Advanced technology reduces nuisance alarms from activities like cooking, and the test/silence button makes it easy to temporarily silence false alarms. UL-certified for reliable performance, this smoke alarm delivers trusted safety for your home.
