In the event of a fire, properly installed and maintained smoke alarms will provide an early warning alarm to your household. This alarm could save your own life and those of your loved ones by providing the chance to escape.
Why Should My Home Have Smoke Alarms?
Smoke alarms are one of the best safety devices you can buy and install to protect yourself, your family, and your home.
What Types of Smoke Alarms Are Available?
There are many different brands of smoke alarms available on the market but they fall under two basic types: ionization and photoelectric. Ionization alarms sound more quickly when a flaming, fast moving fire occurs. Photoelectric alarms are quicker at sensing smoldering, smoky fires. There are also combination smoke alarms that combine ionization and photoelectric into one unit, called dual sensor smoke alarms.
Because both ionization and photoelectric smoke alarms are better at detecting distinctly different yet potentially fatal fires, and because homeowners cannot predict what type of fire might start in a home, the USFA recommends the installation of both ionization and photoelectric or dual sensor smoke alarms.
I Have A Hearing Disability. Are there smoke alarms made to help me?
Yes, these alarms may use strobe lights that flash and/or vibrate to assist in alerting those who are unable to hear standard smoke alarms when they sound.
I cannot afford to purchase a smoke alarm or physically cannot install one. What can I do?

Helpful Tip
Pick a holiday or your birthday and replace the batteries each year on that day.
If your smoke alarm starts making a "chirping" noise, replace the batteries and reset it.
How Long will my Smoke Alarm Last?
Most alarms installed today have a life span of about 5-10 years. After this time, the entire unit should be replaced. It is a good idea to write the date of purchase with a marker on the inside of your alarm so you will know when to replace it. Some of the newer alarms already have the purchase date written inside. In any event, always follow the manufacturer's instructions for replacement.

Anything Else I Should Know?
Some smoke alarms are considered to be “hard-wired.” This means they are connected to the household electrical system and may or may not have battery backup. It's important to test every smoke alarm monthly and replace the batteries with new ones at least once a year.
