Working Smoke Alarms Save Lives
Every year in the United States, about 2,500 people die in home fires.
Most of these deaths occurred in homes that didn’t have a working smoke alarm.
Why should I have a working smoke alarm?
A properly installed and maintained smoke alarm is the first thing in your home that can alert you and your family to a fire
24 hours a day, seven days a week. Home fire sprinklers can also alert you, but are a few seconds slower than smoke alarms. Whether you’re awake or asleep, a working smoke alarm is constantly on alert, scanning the air for fire and smoke.
According to the National Fire Protection Association, almost two-thirds of home fire deaths resulted from fires in properties without working smoke alarms. A working smoke alarm significantly increases your chances of surviving a deadly home fire.
What types of smoke alarms can I buy?
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 detecting different types of fires. Since no one can predict what type of fire might start in their home, the NFPA 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.
There are also alarms for people with hearing loss. These alarms may be strobe lights that flash and/or vibrate to alert those who are unable to hear standard smoke alarms when they sound.
What powers a smoke alarm?
Smoke alarms are powered by battery or by your home’s electrical system. If the smoke alarm is powered by battery, it runs on either a disposable 9-volt battery or a non-replaceable 10-year lithium (“long life”) battery. Alarms that get power from your home’s electrical system, or “hardwired,” usually have a back-up battery that will need to be replaced once a year.
