Carbon monoxide is a silent killer, and many individuals may not realize they are being poisoned until it is too late. Symptoms of CO poisoning mimic those of the flu, making it difficult to detect without the proper equipment. A carbon monoxide alarm is crucial for protecting your family from this dangerous gas.

The First Alert CO400 alarm's advanced electrochemical sensor can detect CO levels accurately and is powered by a replaceable 9V battery for continuous monitoring, even during power outages. The alarm emits an 85-decibel sound when dangerous CO levels are detected and should last for 5-6 seconds during the alarm sequence. In the event of a non-alarming unit, ensure correct battery installation and test again. If the alarm still does not sound, replace it immediately.

For maximum protection, it is recommended to place a carbon monoxide alarm on each level of your home and in every bedroom. The product comes with a 5-year limited warranty and features an end-of-life signal chirp to indicate when it is time for a replacement. All First Alert CO alarms are rigorously tested to meet UL standards, providing the most trusted brand in home safety since 1958.
