1) Get enough to cover every level of your home and every bedroom.
2) If you can, get “interconnected” smoke alarms. When one alarm goes off, they all sound. This means the alarm near you will go off sooner. It gives you more time to get your family outside to safety.
3) There are two kinds of smoke alarms – photoelectric and ionization. If possible, get some of each kind or buy “combination” smoke alarms that have both types of sensors.
4) Make sure your smoke alarms have been tested for safety by a laboratory. Look for a mark on the box such as ETL, UL or CSA.
