You&rsquo;ve replaced the battery. You&rsquo;ve checked the age. But it still chirps or sounds a false alarm at the worst possible moment.</p> <p>The most likely culprit? Dust.</p> <p>Dust is the single most common cause of smoke detector false alarms and mysterious chirping. It gets inside the sensor chamber, blocks the light path in photoelectric detectors, interferes with the ionization chamber in ionization detectors, and tricks your alarm into thinking there&rsquo;s smoke when there isn&rsquo;t.</p>
