Lifespan of Smoke Alarms
Smoke alarms should be replaced every 10 years.
Smoke Alarm Maintenance
Every month your smoke alarm should be tested by pressing and holding the test button until the alarm sounds. It should also be cleaned every six months by gently vacuuming the exterior of the alarm. For battery operated alarms the batteries should be replaced once a year, a good time is when you change your clocks in either the spring or fall. Batteries should also be replaced when the alarm makes a chirping sound.
Locations to Install a Smoke Alarm
Follow the manufacturer’s instructions, but some key points include:
- On the ceiling
- Away from windows, doors or registers where drafts could prevent smoke from reaching the alarm
- Outside of each sleeping area and on every level of the home, including the basement
Types of Smoke Alarms
Both Ionization alarms and Photoelectric alarms are acceptable for residential use; just ensure that the alarm has been tested to the CAN / ULC S531-M standard.
