Installing and Maintaining Smoke Alarms

Posted on: Wednesday, 19 April 2017 at 3:13:29 PM

In SINGLE-LEVEL homes smoke alarms must be installed on or near the ceiling:

  • In all hallways leading to bedrooms
  • Where there is no hallway, in an area near the bedrooms.

In MULTI-LEVEL homes smoke alarms must be located:

  • On each level containing bedrooms (see above instructions for a single level home), and
  • On every other level not containing bedrooms and where people travel, such as on a wall or ceiling in the stairway.

Once you have your smoke alarms installed correctly, it’s important to maintain them regularly.

  • Each month, test your smoke alarm by holding down the test button until you hear a loud alert tone.
  • Every six months vacuum your smoke alarm with a soft brush attachment to remove the build-up of dust and cobwebs.
  • Replace your smoke alarms every 10 years.

And remember, smoke alarms are extremely sensitive and may detect smoke and moisture created by common household activities. To reduce the likelihood of your smoke alarms going off unnecessarily, avoid installing them near the kitchen, laundry and bathroom and near temperature controlled devices such as air conditioners, heaters and fans.
