Proper placement of smoke alarms is essential to benefit from the early detection of the products of combustion. 

Install alarms on the ceiling in every sleeping area, immediately outside of the sleeping area(s), and on every level of the home, including the basement (Reference: 2009 International Residential Code section R314). 

Ceiling-mounted smoke alarms should be located at least 4 inches away from the nearest wall.

Wall-mounted alarms should be located 4 to 12 inches away from the ceiling. 

On a pitched ceiling, the smoke alarm should be installed at the ceiling’s highest point.

Smoke alarms are not recommended in areas that are susceptible to unintentional activations such as kitchens, bathrooms, or garages because of the smoke, dust, or moisture generated in these areas.

*Note: Smoke alarms should always be installed in accordance with the manufacturer’s recommendations.

To ensure smoke alarms function properly, batteries should be checked each month by pressing the test button on the smoke alarm.  If the audible warning sounds, the battery check is successful.  Batteries should be replaced every 6 months.  A good time to install new batteries is when daylight savings time begins and ends; “Change your clock – Change your battery”.   According to most manufacturers’ recommendations, smoke alarms should be replaced after 10 years of use.

By following these simple smoke alarm tips, you and your family have a much better chance of surviving a fire in your home.
