There are many brands of smoke alarms on the market, but they fall under two basic types - ionization and photoelectric.
Ionization and photoelectric smoke alarms detect different types of fires. Since no one can predict what type of fire might start in their home, the USFA recommends that every home and place where people sleep have:
- Both ionization AND photoelectric smoke alarms. OR
- Dual sensor smoke alarms, which contain both ionization and photoelectric smoke sensors.
Choose interconnected smoke alarms, so when one sounds, they all sound.
Be sure that you are purchasing approved alarms. Health Canada recently issued an alert to consumers to check for a recognized Canadian certification mark on the product when purchasing smoke or carbon monoxide (CO) alarms after multiple unapproved devices were found on the market. Products that do not have a recognized Canadian certification mark may not meet Canadian performance standards and could fail or operate incorrectly.
