Smoke alarms save lives. Almost two-thirds of home fire deaths resulted from fires in homes with no smoke alarms or no working smoke alarms. When there is a fire, smoke spreads fast and you need smoke alarms to give you time to get out. Learn more on the National Fire Protection Association (NFPA) website.
Where to Place your Smoke Detectors
Install smoke alarms in every bedroom, outside each separate sleeping area, and on every level of the home, including the basement. Interconnect all smoke alarms throughout the home. When one sounds, they all sound.
Smoke rises; install smoke alarms following the manufacturer's instructions high on a wall or on a ceiling. Save manufacturer's instructions for testing and maintenance.
Batteries and Testing
Replace batteries in all smoke alarms at least once a year. If an alarm "chirps", warning the battery is low, replace the battery right away. Test alarms at least monthly by pushing the test button.
Visual Alarms for the Hearing Impaired
Smoke alarms are available for people who are deaf or hard of hearing. These devices use strobe lights. Vibration devices can be added to these alarms.
