Product Description
The USI USI/SMCO/REP is a battery-operated combination alarm that helps protect homes from both smoke/fire and carbon monoxide hazards in one compact device. It combines photoelectric smoke sensing with an electrochemical CO sensor, making it a practical option for bedrooms, hallways, living spaces, apartments, rental units, and areas where hardwiring is not available.
This model uses replaceable AA batteries, allowing flexible placement without hardwiring while still supporting ongoing maintenance over the alarm’s service life. The built-in Voice Alert helps users distinguish between fire, CO, and battery replacement alerts, while false-alarm resistance and a Test/Silence button help make everyday use easier.
