What can cause a smoke detector to malfunction?

Dirt and dust accumulation can interfere with the functionality of a smoke detector, leading to potential malfunctions. Smoke detectors operate by using sensors that detect particles in the air. When dust and dirt build up inside the unit, they can obstruct the sensors, cause false alarms, or even prevent the detector from sensing smoke altogether. Maintaining cleanliness is essential for ensuring that detectors operate correctly and can alert occupants in the event of a fire.

While high temperatures can potentially impact the performance of certain types of smoke detectors, they are generally designed to withstand a range of temperatures and do not commonly lead to malfunction. Frequent testing is important for ensuring that smoke detectors are operational, and rather than being a cause of malfunction, regular cleaning enhances their performance and lifespan.
