USI Smoke Alarms are easy to install, reliable, and designed to detect smoke, carbon monoxide, and natural gas early—whether it’s a slow smoldering fire or a fast-burning one. They help reduce false alarms caused by everyday things like cooking, so you won’t have unnecessary service calls. With a 10-year sealed battery, they provide long-lasting protection without much upkeep. For contractors and homeowners, this means a decade of peace of mind, lower material and labor costs thanks to quick installation, and an easier time passing inspections with trusted, up-to-date technology.
