Tomorrow, on Sunday, March 14, states throughout the U.S. will be turning their clocks forward. It's a Spring time ritual, and a night when we lose an hour's sleep.

The West Grove Fire Company reminds everyone that this is also an important time to remember to change the batteries in home smoke detectors and carbon monoxide detectors.

Because working smoke alarms are a critical element of home fire safety, NFPA supports any and all efforts to reinforce the importance of working batteries. However, today’s smoke alarms are not all designed the same, making battery messaging more nuanced.

Following is information to help make sure all smoke alarms have working batteries, accounting for the multiple types of smoke alarms on the market and their varying battery requirements:

Smoke alarms with non-replaceable 10-year batteries are designed to remain effective for up to 10 years. If the alarm chirps, warning that the battery is low, replace the entire smoke alarm right away.

Smoke alarms with any other type of battery need a new battery at least once a year. If that alarm chirps, warning the battery is low, replace the battery right away.

When replacing a battery, follow manufacturer’s list of batteries on the back of the alarm or manufacturer’s instructions. Manufacturer’s instructions are specific to the batteries (brand and model) that must be used. The smoke alarm may not work properly if a different kind of battery is used.

Once every six months, we recommend that you clean your smoke detectors. Cleaning your smoke detectors involves two activities: 1) vacuuming out the unit; and 2) wiping down the outside vents.

To vacuum out the unit, you should follow your manufacturer’s recommendations for routine cleanings. Typically this will involve removing the face of the unit and then using a soft brush attachment for your vacuum cleaner to gently brush and vacuum the inside of your smoke detector (see types, costs, and reviews of vacuum cleaners).

In addition to vacuuming the inside of your smoke detector, you should also use a clean wipe and mild detergent to remove build-up from the outside of your unit. In particular, you will want to clean the vent openings, to ensure that airflow is not obstructed to the sensor inside the unit.

If you are not sure how to clean your smoke detector, you should at least vacuum the outside of the unit, which will draw air through the vents in the face of the unit.
