How long does it take for a Carbon Monoxide Alarm to go off at different levels of CO?
The alarm response times are: 70 PPM = 60-240 minutes, 150 PPM = 10-50 minutes, and 400 PPM = 4-15 minutes. For quicker alerts at higher levels of CO, it is crucial to identify any potential sources around the alarm.
