Smoke Detectors FAQ

Where Should I Install My Smoke Detector?

• Install smoke detectors outside sleeping areas and on every level of the home, including the basement. If people sleep with the bedroom doors closed, detectors should be placed inside every room. Install detectors in hallways, utility rooms and on the ceiling of the basement at the bottom of the stairs. Don't place them in kitchens, bathrooms or garages where fumes or steam will set off nuisance alarms.

What Causes False Alarms?

• Problems that could cause false alarms include smoke from cooking, dust or small dirt particles. Detectors installed too close to fluorescent light fixtures will also have false alarms. If you paint the walls in your home, remember that fresh paint fumes can set an alarm off. Steam originating from the bathroom also confuses smoke detectors.

How Often Should I Test the Alarm?

• Test the alarm once a month. All smoke alarms have a simple test button. If the alarm fails the test, replace the batteries and retest. If it still does not work, replace the unit.

When Should I Replace the Smoke Detector?

• Smoke detectors are designed to last 7 to 10 years. Even if your detector works fine after this time period, replace it. New detectors are inexpensive and more sensitive than units made 10 years ago. You should also replace all smoke detectors if you move to a new home.

Why Is It Beeping?

• Most battery-operated units will beep periodically if the battery needs replacing. Batteries should be replaced on a regular yearly schedule. Some detectors come with a special battery designed to last the life to the smoke detector. Read the owner's manual to determine what type of battery yours is equipped with.

Are Battery Operated Units the Only Kind?

• Hardwired detectors are all connected and operate on electricity. If one goes off, it sets off the whole line. This type would have a battery back up. For hearing impaired people, get a smoke detector that flashes bright lights instead of a horn to warn of smoke.
