How does ionization smoke detector work
WebFeb 11, 2024 · Ionization The first type is Ionization-type smoke detectors. These smoke detectors work by having two plates that each produce either negative or positive ions. These ions then traverse between the two plates, and this creates a complete circuit. WebIn an ionisation type smoke detector, ambient air is allowed to freely enter the ionization chamber. The chamber contains a small amount of americium-241, which is an emitter of alpha particles which produce a constant ion current. If smoke enters the detector, it disrupts this current because ions strike smoke particles and are neutralized.
