Why is my smoke alarm making a funny sound (chirping)? (2)

Any time your smoke detector goes off, it's important to pay attention. If it is sounding the loud alarm it is because it is sensing the presence of smoke-- check your home thoroughly. If you smell smoke and are unable to locate a fire, call 9-1-1 and we will send an engine to make sure that a fire is not smoldering in a hidden area. If you do not 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.

If the detector is just chirping, thumping, or buzzing, it probably means that the battery is low. Replace the battery as soon as possible. If you have replaced the batteries and the chirping persists you may have a faulty detector-- replace the detector as soon as possible. Smoke detectors should be replaced as least every ten years.

Without a working battery, a smoke detector cannot do its job and the risk of dying in a fire increases greatly. If you would like us to inspect the detector, please call the Ross Valley Fire Department and we will come out and assist you.
