Any time your smoke detector goes off, it's important to pay attention. If it's sounding its loud alarm because it senses the presence of smoke, check your home thoroughly. If you smell smoke and are unable to locate a fire, call 911 and we'll send an engine to make sure that a fire isn't smoldering in a hidden area and it won't cost anything. If you don't smell smoke, the detector may be reacting to the presence of dust, steam, or a small insect or spider. Dust and bugs can be removed by a vacuum cleaner. If steam from a nearby shower is affecting your smoke detector regularly, move the detector to a different spot.
Replacing the Battery
If the detector is just chirping, thumping, or buzzing, it probably means that the battery is low. Replace the battery as soon as possible. Without a working battery, a smoke detector can't do its job and the risk of dying in a fire increases greatly.
