Smoke Alarm Questions and Answers
Which smoke alarm should I buy?
Buy only smoke alarms that carry the label of an independent testing laboratory.
Several types of smoke alarms are available. Some run on batteries and others on household current. Some detect smoke using an “ionization” sensor; others use a “photoelectric” detection system. All approved smoke alarms, regardless of type, will offer adequate protection provided they are installed and maintained properly.
How many smoke alarms do I need?
Install a smoke alarm outside each sleeping area and on every level of the home, including the basement. On floors without bedrooms, smoke alarms should be installed in or near living areas, such as dens, living rooms or family rooms.
Be sure everyone sleeping in your home can hear your smoke alarms. If any residents have hearing impairments or sleep with bedroom doors closed, install additional smoke alarms inside sleeping areas as well. There are special smoke alarms that flash a light in addition to sounding an audible alarm.
For extra protection, NFPA suggests installing smoke alarms in dining rooms, furnace rooms, utility rooms and hallways.
How do I install smoke alarms?
Most battery-powered smoke alarms can be installed using only a drill and a screwdriver, by following the manufacturer’s instructions. Smoke alarms can also be hard-wired into a buildings electrical system. A qualified electrician should install hard-wired smoke alarms.
Where do I install my smoke alarms?
Mount smoke alarms on the ceiling. The smoke alarm should be attached at least 12 inches from the nearest wall. In a room with a pitched ceiling, mount the smoke alarm at or near the ceiling’s highest point.
Don’t install a smoke alarm too near a window, door, or forced air register where drafts could interfere with the smoke alarms operation.
