Is Your Smoke Detector Yellow?

If the answer is “Yes!”, it might be time to replace your smoke detector. The life expectancy of smoke alarms is generally 8-10 years, after which point their sensors can begin to lose sensitivity.

Don’t be tricked into a false sense of security. Keep your home safe and your family protected by ensuring your smoke detectors are replaced before they expire.


  • Ensure you have the correct number of units for your home – in Lexington, KY, smoke detectors are required within eight feet of each sleeping area, plus on each level of the unit
  • Check your batteries regularly to ensure your units are functioning – if your unit isn’t functioning, you may not be alerted to fire in time for you and your family to exit your home safely
  • Monitor each unit’s expiration date, and replace them every 8-10 years – even if your unit beeps, the smoke sensor may not be functional

Know How Many Units Your House Should Have

Unless your house was built recently, it’s likely that you may not have enough smoke detectors. Here are the guidelines published by the National Fire Prevention Association:

  • Choose smoke alarms that have the label of a recognized testing laboratory.
  • Install smoke alarms inside each bedroom, outside each sleeping area and on every level of the home, including the basement.
  • On levels without bedrooms, install alarms in the living room (or den or family room) or near the stairway to the upper level, or in both locations.
  • Smoke alarms installed in the basement should be installed on the ceiling at the bottom of the stairs leading to the next level.
  • Smoke alarms should be installed at least 10 feet (3 meters) from a cooking appliance to minimize false alarms when cooking.
  • Mount smoke alarms high on walls or ceilings (remember, smoke rises). Wall-mounted alarms should be installed not more than 12 inches away from the ceiling (to the top of the alarm).

Check Your Batteries Regularly

Check Your Batteries Regularly

You should test the batteries in your smoke detector monthly.

To test the battery in your smoke detector, press and hold the test button. After a few seconds, you should hear a loud, ear-piercing siren while the button is pressed. If the sound is weak or nonexistent, replace your batteries.

“Don’t Wait – Check the Date!”

Once you have ensured you have the right number of smoke detectors, you’ll need to replace them before they expire. Unless your house was built within the last decade, chances are one or more of your smoke detectors is expired.

  1. Remove the smoke alarm from the wall or ceiling.
  2. Look at the back of the alarm for the date of manufacture.
  3. Smoke alarms should be replaced 10 years from the date of manufacture.
  4. Put the alarm back on the ceiling or wall if it's less than 10 years old.
