My smoke detector chirps occasionally, what is wrong?
If this is a battery powered detector, the chirping typically indicates a weak battery. Try replacing the battery, if that does not solve the problem replace the detector. • My smoke detector goes off for no reason, but only for a few seconds, what can be wrong? This may be caused by dust or a small insect in the sensing part of the detector. Try vacuuming the outside of the detector to remove the problem and replace if there is no improvement.
