How do Carbon Monoxide Detectors Work?
Carbon monoxide detectors trigger an alarm based on an accumulation of carbon monoxide over time. Carbon monoxide can harm you if you are exposed to high levels of carbon monoxide in a short period of time, or to lower levels of carbon monoxide over a long period of time. Carbon monoxide detectors require a continuous power supply, so if the power cuts off then the alarm becomes ineffective. Models are available that offer back-up battery power.
