Installation and Maintenance Tips

• Install smoke alarms on every level of your home, including the basement, making sure that there is an alarm outside every separate sleeping area. New homes are required to have a smoke alarm in every sleeping room and all smoke alarms must be interconnected.
• Hard-wired smoke alarms operate on your household electrical current. They can be interconnected so that every alarm sounds regardless of the fire’s location. This is an advantage in early warning, because it gives occupants extra time to escape if they are in one part of the home and a fire breaks out in another part. Alarms that are hard-wired should have battery backups in case of a power outage, and should be installed by a qualified electrician.
• If you sleep with bedroom doors closed, have a qualified electrician install interconnected smoke alarms in each room so that when one alarm sounds, they all sound.
• If you, or someone in your home is deaf or hard of hearing, consider installing an alarm that combines flashing lights, vibration and/or sound.
• Mount smoke alarms high on walls or ceilings (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.
• If you have ceilings that are pitched, install the alarm near the ceiling’s highest point.
• Don’t install smoke alarms near windows, doors, or ducts where drafts might interfere with their operation.
• Never paint smoke alarms. Paint, stickers, or other decorations could keep the alarms from working.

Safety Tips

• Install smoke alarms in every bedroom, outside each separate sleeping area and on every level of the home, including the basement. Interconnect all smoke alarms throughout the home. When one sounds, they all sound.
• An ionization smoke alarm is generally more responsive to flaming fires, and a photoelectric smoke alarm is generally more responsive to smoldering fires. For the best protection, both types of alarms or a combination alarm (photoelectric and ionization) should be installed in homes.
• Test alarms at least monthly by pushing the test button.
• Smoke rises; install smoke alarms following manufacturer’s instructions high on a wall or on a ceiling. Save manufacturer’s instructions for testing and maintenance.
• Replace batteries in all smoke alarms at least once a year. If an alarm “chirps,” warning the battery is low, replace the battery right away.
• Replace all smoke alarms, including alarms that use 10-year batteries and hard-wired alarms, when they are 10 years old or sooner if they do not respond properly.
• Be sure the smoke alarm has the label of a recognized testing laboratory.
• Alarms that are hard-wired (and include battery backup) must be installed by a qualified electrician.
• If cooking fumes or steam sets off nuisance alarms, replace the alarm with an alarm that has a “hush” button. A “hush” button will reduce the alarm’s sensitivity for a short period of time.
• An ionization alarm with a hush button or a photoelectric alarm should be used if the alarm is within 20 feet of a cooking appliance.
