Customer Reviews For The Hardwire Smoke & Fire Alarm with 10-Year Battery Backup

Yes. This hardwired smoke detector supports multi-station interconnectivity with up to 24 compatible devices (including up to 18 smoke alarms). When wired into your home’s electrical circuit, triggering one alarm causes all connected hardwired smoke alarms throughout the residence to sound simultaneously.

Yes. Designed to meet UL 217 (9th Edition) safety standards, its multi-criteria sensor technology is specifically calibrated to distinguish between actual fire hazards and non-emergency steam or routine cooking vapors, significantly reducing nuisance false alarms.

Turn off power at the main circuit breaker, remove your old mounting bracket, and attach the included quick-connect wiring harness (line, neutral, and interconnect wires) to your electrical junction box. Once secured to the mounting base, the sealed 10-year battery backup activates automatically.

This hardwired smoke detector includes built-in voice warnings that clearly announce emergency hazards rather than relying solely on standard beeping patterns. During a fire event, the unit explicitly speaks the nature of the emergency alongside the 85 dB horn, and it provides spoken updates when the unit reaches its end of service life or needs attention.

If your home loses main AC power, the hardwired smoke alarm with 10-year battery backup seamlessly transitions to its sealed internal lithium power battery. Your home remains continuously protected against smoke and fire threats throughout electrical blackouts without interrupting interconnection or requiring manual adjustments.
