An important line of defense for the ones you love
Not too long ago, carbon monoxide detectors were only for people who had sophisticated alarm systems in their homes. Today most every family is aware of the dangers of carbon monoxide poisoning and have at least one CO detector in their home. The smartest families have CO detectors installed on every level of their home, including one next to their heating equipment. This is the safest way to protect your family from deadly carbon monoxide poisoning.
When a smoke detector makes a consistent, frequent chirping noise, it means it's time to change the battery. If it's still making the chirping noise at the same pace after you have changed the battery, then you need to press the test button on the outside of the detector to reset it. If the detector chirps at random intervals, it may be broken and needs to be replaced.
