Installing & Testing Smoke Alarms
Installing Your Smoke Detectors Correctly
- Install smoke alarms that are Underwriter Listed (examined and tested to appropriate product safety standards) by a qualified testing laboratory on every level of your home, including the basement (but not unfinished attics). Make sure there is an alarm in or near every sleeping area.
- Mount the smoke alarms high on ceilings or walls – remember, smoke rises. Ceiling-mounted alarms should be installed at least four inches away from the nearest wall; wall-mounted alarms should be installed four to 12 inches away from the ceiling.
- Don't install smoke alarms near windows, outside doors, or ducts where drafts might interfere with their operation.
- Don't paint your smoke alarms; paint or other decorations could keep them from working when you most need it.
