Product Description
The USI/SMCO/HW10YR/P is a hardwired combination alarm designed to help protect homes from both fire and carbon monoxide hazards in one installed unit. It combines photoelectric smoke sensing with an electrochemical CO sensor, making it a strong option for bedrooms, hallways, living areas, and multi-level homes where both smoke and CO coverage are needed.
This model is interconnectable, so compatible hardwired alarms can sound together throughout the home. The built-in Voice Alert helps distinguish between fire alerts, CO alerts, and replacement reminders, while the sealed 10-year lithium backup battery helps maintain protection during power outages and reduces routine battery replacement work.
