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. 

Here's what you need to know!
  • A closed door may slow the spread of smoke, heat and fire. Install smoke alarms in every sleeping room and outside each separate sleeping area. Install alarms on every level of the home. 
  • Smoke alarms should be interconnected. When one sounds, they all sound. 
  • Large homes may need extra smoke alarms.
  • Test your smoke alarms at least once a month. Press the test button to be sure the alarm is working.
  • When a smoke alarm sounds, get outside and stay outside.
  • Replace all smoke alarms in your home every 10 years.
  • There are two kinds of alarms. Ionization smoke alarms are quicker to warn about flaming fires. Photoelectric alarms are quicker to warn about smoldering fires. It is best to use of both types of alarms in the home.  Learn more in the box on the right side of this page. 

The two most commonly recognized smoke detection technologies are ionization smoke detection and photoelectric smoke detection.

For each type of smoke alarm, the advantage it provides may be critical to life safety in some fire situations. Home fatal fires, day or night, include a large number of smoldering fires and a large number of flaming fires. You can not predict the type of fire you may have in your home or when it will occur. Any smoke alarm technology, to be acceptable, must perform acceptably for both types of fires in order to provide early warning of fire at all times of the day or night and whether you are asleep or awake.

For best protection, use both types of smoke alarm technologies

For best protection, it is recommended both (ionization and photoelectric) technologies be used in homes. In addition to individual ionization and photoelectric alarms, combination alarms that include both technologies in a single device are available.
