How does ionization smoke detector work
WebThere is a photoelectric detector at the other end. It detects the light coming, which tells the system that the circuit is complete. However, when smoke enters inside, the smoke obstructs the light. The redirected light falls into the photocell, which is present inside the chamber. When this photocell detects light, it rings the alarm.

WebJan 7, 2024 · How they work Ionization chamber smoke detectors rely on radiation to "ionize" the air inside the chamber. A radioactive source "decays," or sheds particles and photons from unstable atoms. The … WebHow They Work. The ionization chamber in a smoke detector is essentially just two metal plates at different voltages. The ambient air molecules flow between the plates, where they are ionized by the radiation source (see …
WebAug 31, 2024 · An ionization model uses radioactive material positioned between two electrically charged plates to ionize the air inside it. This creates a current flow between the two plates. Smoke sets off the alarm when it disrupts the ion flow. These alarms are most responsive to fires with blazing flames.

This type of smoke detector is more common because it is inexpensive and better at detecting the smaller amounts of smoke produced by flaming fires. Inside an ionization detector is a small amount (perhaps 1/5000th of a gram) of …
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.
