About This Product
Ensure reliable home safety with the USI Hardwired Smoke Alarm with 10-Year Battery Backup. Featuring Sensing Plus Multi-Criteria Detection, this advanced alarm accurately detects both slow-burning and fast-flaming fires for early warning and rapid response. The hardwired alarm can connect with other compatible alarms in your home to provide full coverage, while the Quick-Find Alarm Origination pinpoints the source of the alert. The 10-Year Backup Battery provides continuous protection and replaces low-battery chirps with a single end-of-life alert after 10 years. Advanced technology minimizes nuisance alarms from everyday activities like cooking, and the test/silence button allows easy silencing of false alarms. UL-certified for reliability and performance, this smoke alarm is a trusted choice for protecting your home and loved ones.
