About This Product

The USI Hardwired Smoke Alarm with 10-Year Battery Backup delivers reliable, comprehensive protection for your home. Featuring Sensing Plus Multi-Criteria Detection, it accurately identifies both slow-burning and fast-flaming fires for early alerts and rapid response. This hardwired alarm can interconnect with other compatible alarms throughout your home, providing full coverage, while the Quick-Find Alarm Origination feature pinpoints the source of the alarm.

The 10-Year Backup Battery ensures continuous protection and replaces frequent low-battery chirps with a single end-of-life alert after 10 years, reminding you to replace the unit. Advanced technology reduces nuisance alarms from activities like cooking, and any false alarms can be easily silenced using the test/silence button.
