Smoke Alarms – FAQs

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 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.There are also alarms for people with hearing loss. These alarms may have 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.

Where do I put smoke alarms in my home?

Remember, a closed door may slow the spread of smoke, heat and fire.

Put smoke alarms:

Inside and outside of each bedroom and sleeping area.
On every level of the home.

For added safety:

Smoke alarms should be interconnected. When one sounds, they all sound.
Place smoke alarms on the ceiling or high on the wall. Check the manufacturer’s instructions for the best place for your alarm.
Only qualified electricians should install hardwired smoke alarms.

Some fire departments will install battery-operated smoke alarms in your home at no cost. Contact your local fire department’s non-emergency phone number for more information.
