About This Product

Ensure reliable protection with the USI Hardwired Smoke Alarm with 10-Year Battery Backup. Featuring Sensing Plus Multi-Criteria Detection, this advanced photoelectric alarm effectively detects both slow-burning and fast-flaming fires for early alerts and rapid response. It can be interconnected with other hardwired alarms in your home to provide comprehensive coverage. The 10-year sealed backup battery ensures uninterrupted protection and replaces frequent low-battery alerts with a single end-of-life notification after 10 years. The alarm’s voice function clearly distinguishes between fire alerts and replacement reminders. Advanced technology helps reduce false alarms caused by everyday activities such as cooking, and the test/silence button allows you to easily quiet any unwanted alerts. With UL certification, you can trust the performance and reliability of USI Hardwired Smoke Alarms. Rely on USI’s 50+ years of experience in home safety for long-lasting protection for your household.
