About This Product

The USI Hardwired Smoke Alarm with 10-Year Battery Backup provides advanced, reliable protection for your home. Featuring Sensing Plus® Multi-Criteria Detection, this ionization alarm accurately identifies both slow-burning and fast-flaming fires for early detection and rapid response.

This hardwired alarm can interconnect with other compatible alarms in the home, ensuring comprehensive coverage throughout your space. The Quick-Find Alarm Origination feature makes it easy to identify the source of an alarm. The 10-year backup battery ensures continuous protection, replacing low-battery chirps with a single end-of-life alert after 10 years to remind you to replace the unit.
