Product Description
The USI USI/SMCO/10YR/V is a 3-in-1 residential safety alarm that combines smoke, fire, and carbon monoxide detection in one compact unit. It uses photoelectric smoke sensing with Sensing Plus Multi-Criteria Detection and includes an electrochemical CO sensor, helping provide coverage for both fire events and carbon monoxide hazards.
Designed for long-term household protection, this alarm uses a sealed 10-year battery to reduce battery replacement maintenance and help maintain protection during power failures. The built-in Voice Alert helps distinguish between fire alerts, CO alerts, and replacement reminders, while false-alarm resistance and a Test/Silence button make everyday use easier for homeowners, landlords, and property managers.
