The following are tips to keep in mind when it comes to smoke detectors.
Periodically test all your smoke detectors to ensure they are working properly. Follow the manufacturer's instructions and check each detector in your home at least once a month.
Change the batteries in your smoke detector at least twice per year.
When you change the battery, plan on cleaning the detector at the same time. Follow the manufacturer's instructions on how to clean it.
Promptly replace the battery when the low-battery indicator makes a "chirping" sound. Plan to replace the battery in the alarm at least twice a year. We recommend that you replace the battery when you change your clocks for daylight saving time in the spring and when you change back to standard time in the fall.
Make sure all people living in your home are familiar with the sound of the alarm. Studies have demonstrated that the sound of the alarm may not awaken children.
Use a permanent marker to write the purchase date on the inside of the removable cover and replace your detector with a new one about every ten years. Smoke detectors with 10-year batteries are now available; follow the manufacturer's instructions and recommendations for battery replacement for a detector with a long-life battery.
Install a smoke detector outside sleeping areas and on every level of your home, including the basement.
