More house fires happen during the winter than any other time of the year. Prepare to keep your home safe by testing your smoke detector ahead of this season. 

We will walk you through a step-by-step process of how to test your smoke detector, replace batteries, and prevent a fire.

How to Test a Smoke Detector

According to the U.S. Fire Administration (USFA), smoke detectors should be tested at least once a month and batteries should be replaced at least once or twice a year. A chirping detector also indicates that the device is low on juice.

To test your alarm, follow these basic instructions:

1. Alert anyone in your home beforehand. When active, smoke detectors make a very high-pitched noise and may frighten some, especially small children.
2. Station someone else at the furthest point from the alarm in your home. This ensures the alarm can be heard throughout the entire house. You may want to install additional detectors where the sound is low or muffled.
3. Press and hold the button on the smoke detector. It may take a few seconds to start, but you should soon hear the device making a loud, ear-piercing siren. If the sound is weak or nonexistent, replace your batteries.

If you need additional guidance on replacing your smoke detector’s batteries, keep these simple steps in mind:

1. Gently move the cover or unclip the body of the detector from its base with a slight twisting motion. Inside, you will find three main parts: the sensing chamber, a loud horn, and a battery (and, in some cases, house voltage power source).
2. Unclip the old battery from its holder. Most detectors utilize a 9-volt battery—use a brand new lithium 9-volt battery as a replacement. Be sure the male and female terminals are properly oriented and connect soundly with the base.
3. Snap the cover shut or lock the body of the smoke detector back into its base.
4. Press the test button on the detector’s surface to ensure the battery is working. When the button is pressed, the detector should beep or chirp.

Specific instructions on battery replacement or tests may vary depending on your smoke detector. So, be sure first to find your manufacturer’s instructions. If this physical guide is long gone, don’t fret. Try searching online. 

Also, note that the normal life span of a smoke detector is around a decade. This will also be indicated in the manufacturer’s guide.
