Most carbon monoxide (CO) alarms are designed to sound when CO levels reach 70 parts per million (ppm) or higher for 60 to 240 minutes. Higher concentrations, such as 150 ppm or 400 ppm, will trigger the alarm more quickly, often within 10 to 50 minutes. Always refer to your specific alarm’s manual for exact thresholds.
