The dual-sensor design includes a photoelectric smoke sensor for smoldering fires and an electrochemical CO sensor with precise 1 ppm resolution, monitoring levels from 0–2000 ppm. With ETL listings for both US (UL) and Canadian (CAN/ULC) standards, it meets rigorous residential safety requirements. Installation is effortless with a twist-and-click mounting bracket—no wiring needed—and its compact 4.9-inch diameter fits seamlessly in bedrooms, hallways, or living spaces. A loud 85dB alarm with LED indicators and a test/silence button ensures quick response when needed.
