Dual-Gas Protection: Carbon monoxide (CO) detection helps prevent poisoning from faulty heating systems, fireplaces, or vehicle exhaust, while carbon dioxide (CO2) monitoring indicates ventilation quality in enclosed areas such as homes, indoor growing spaces, or wine cellars offering full protection against multiple hazards
How to Properly Test CO: Easily verify detector responsiveness by placing a small smoke source, such as burning paper or a cigarette, near the sensor keeping a safe distance from smoke or ash. The alarm should activate within seconds. Not recommended to test with car exhaust or gas stoves, as normal operation usually does not release detectable CO
