Smoke Alarms
Smoke alarms save lives. Smoke alarms that are properly installed and maintained play a vital role in reducing fire deaths and injuries. If there is a fire in your home, smoke spreads fast and you need smoke alarms to give you time to get out. Keep your family safe by installing smoke alarms and testing them monthly to make sure they work.
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 nine-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.
Is your smoke alarm still working? A smoke alarm with a dead or missing battery is the same as having no smoke alarm at all. A smoke alarm only works when it is properly installed and regularly tested. Take care of your smoke alarms according to the manufacturer’s instructions. Below are some general maintenance tips.
Smoke alarm powered by a nine-volt battery
- Test the alarm monthly.
- Replace the batteries at least once every year.
- Replace the entire smoke alarm every 10 years.
Smoke alarm powered by a 10-year lithium (or “long-life”) battery
- Test the alarm monthly.
- Since you cannot (and should not) replace the lithium battery, replace the entire smoke alarm according to the manufacturer’s instructions.
Smoke alarm that is hardwired into your home’s electrical system
- Test the alarm monthly.
- Replace the backup battery at least once every year.
- Replace the entire smoke alarm every 10 years.
- Three out of five home fire deaths in 2009-2013 were caused by fires in homes with no smoke alarms or no working smoke alarms.
- Working smoke alarms cut the risk of dying in reported home fires in half.
- In fires considered large enough to activate the smoke alarm, hardwired alarms operated 94% of the time, while battery powered alarms operated 80% of the time.
- When smoke alarms fail to operate, it is usually because batteries are missing, disconnected, or dead.
- An ionization smoke alarm is generally more responsive to flaming fires and a photoelectric smoke alarm is generally more responsive to smoldering fires. For the best protection, or where extra time is needed to awaken or assist others, both types of alarms, or combination ionization and photoelectric alarms are recommended.
