Smoke Alarm FAQs
Residential smoke alarms are rated for 10 years.
Follow manufacture's guidelines but when in doubt, replace the alarm.
Date of manufacture can be found on the back of your alarm.
If the date is missing or unreadable, replace the alarm.
Test smoke alarms at least once a month and replace batteries at least every year. Replace alarms as noted.
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.
Smoke alarms can be installed on the ceiling or wall. For ceiling installation, mount alarm toward the middle of the ceiling, no closer than four inches from walls. If ceiling installation is not possible, mount alarms on the wall, no closer than four inches from the ceiling.
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.
