Smoke alarms come in several types, including hardwired (electrically connected), battery-operated, or a combination of both. When replacing a smoke alarm, always install the same type as the existing unit, whether battery-operated, hardwired, or combination.
Smoke alarms should be installed on every level of your home and outside all sleeping areas. Alarms older than 10 years should be replaced, as smoke alarms have a limited lifespan. Depending on the age of your home, you may also have smoke alarms installed inside individual bedrooms.
For best performance, smoke alarms should be mounted on the ceiling. Avoid installing them near bathrooms, heating appliances, windows, or ceiling fans, as these can interfere with proper operation. Always follow the manufacturer’s installation instructions.
Test your smoke alarms monthly by pressing the test button and ensuring the alarm sounds.
If your smoke alarm begins to chirp or beep, replace the battery immediately. Standard batteries should be replaced twice a year, typically when daylight saving time begins and ends. Some newer smoke alarms include a sealed 10-year battery, which does not require replacement during the life of the alarm.
Where to Install
- Homes built before 2012. Smoke alarms are required on every level of your home and outside of bedrooms. While houses built before the 2012 Building Code are not required to have smoke alarms installed inside every bedroom, you may choose to do so to provide better protection for your family
- Homes built after 2012. Smoke alarms are required on every level of your home, outside of bedrooms, and inside each bedroom.
- Do not install in the kitchen. This is a common myth, but smoke alarms should not be installed in the kitchen. Today’s alarms are designed to be sensitive, and being too close to a stove or toaster will cause the alarm to go off every time you cook. Try installing it the living room instead!
Maintenance
Test your smoke alarms monthly!
Batteries should be changed twice a year, even hardwired smoke alarms!
You want your alarm to work, even when the hydro is out.
Smoke alarms expire 10 years after the manufacture date. You can find this date on the back of your alarm, or some have a “replace by” sticker on the side
