Why Is My Home Fire Alarm Going Off for No Reason?
False alarms have several causes. (Jupiterimages/Photos.com/Getty Images)

Smoke detectors are sensitive to changes in the air and sometimes sound an alarm when a fire isn't present. Installing smoke detectors properly reduces the chances of a false alarm.

Causes

Changes in moisture, such as moisture from a shower or steam from cooking, may set off a smoke detector. Dust can set off smoke detectors, as can fresh paint fumes. Smoke detectors may also beep repeatedly when their batteries are dying.

Warning

Do not take the batteries out of a smoke alarm when it sounds a false alarm. You may forget to replace the batteries later, leaving your home and family in danger. Fanning with a newspaper may silence the alarm. You can also temporarily silence some models.

Considerations

Installing smoke detectors according to the manufacturer's instructions reduces the chances of a false alarm. For example, you shouldn't install detectors near windows or air ducts because changes in air flow may set off the alarm or interfere with its functioning. In addition, remember to clean your detector regularly according to the manufacturer's instructions.
