Working smoke alarms that will wake you are important. Install smoke alarms in every sleeping room, outside each separate sleeping area, and on every level of the home, including the basement. Larger homes may require additional smoke alarms to provide a minimum level of protection.
Interconnect all smoke alarms throughout the home for the best protection. When one sounds, they all sound. Make sure you can hear the sound of the smoke alarm.
Replace all smoke alarms when they are 10 years old. Replace any smoke alarm that does not respond after a new battery has been installed. Replace combination smoke-carbon monoxide alarms according to the maufacturer's recommendations.
Smoke alarms with nonreplaceable (long-life) batteries are designed to remain effective for up to 10 years. If the alarm chirps, warning that the batter is low, replace the entire smoke alarm right away.
For smoke alarms that don't have nonreplaceable or long-life batteries, replace batteries once a year. If the alarm chirps, replace the battery immediately.
Alarms are available for people who are deaf, people with significant hearing loss, people who use hearing aids but not when they sleep, and people who do not wake to the sound of a traditional smoke alarm.
When people who are deaf or people who use hearing aids are asleep, a pillow or bed shaker should be used. When people who are hard of hearing are asleep, a loud, mixed, low-pitched sound alert should be used. A pillow or bedshaker is a good idea. These devices are activated by the sound of the standard smoke alarm.
