FAQs

Smoke Alarms
How often should I change the batteries in my smoke alarms?
Some smoke alarms have built in lithium-ion batteries that can't be changed.  If the battery is bad, the alarm must be replaced.  Smoke alarms with standard batteries should be changed at least annually.  Test your alarms monthly to ensure they are working properly.
How many smoke alarms should I have in my home?
Smoke alarms should be installed in every bedroom, outside each sleeping area, and on every level of your home. In the basement, install on the ceiling at the bottom of the stairs. On levels without bedrooms, install in the common room or near the stairway.
When should I replace my smoke alarms?
Most residential alarms should be changed out every 10 years or earlier if an alarm is not working properly.  Follow manufacturers guidelines but when in doubt, change it out.  
How do I ensure proper activation and avoid nuisance alarms?
Smoke alarms installed within 20 feet of a cooking appliance should be equipped with a means of alarm silencing or be photoelectric. Smoke alarms should not be installed within 3 feet of a bathroom with tub or shower, in a garage, within 3 feet of an air register, near doorways or windows with the potential for drafts, or on an uninsulated exterior wall or ceiling.
What if I am hard of hearing or deaf?
Deaf/Hard of Hearing Smoke Alarms, commonly called "bed-shakers," are not smoke alarms. Rather, they work with smoke alarms in the home to notify deaf/hard of hearing individuals of a possible life-threatening fire emergency.
