Web13 nov. 2024 · Ionization Smoke Detectors. This type of smoke detector uses ionized particles to detect the presence of smoke. Each ionization smoke detector holds a tiny amount of radioactive material, which is placed between two electrically charged plates. The reaction between these components causes the ionization of air. WebWhen smoke molecules enter the ionization chamber, the smoke particles attach to the ions and neutralize them. Consequently, the total number of ionized particles in the chamber is reduced. This reduction yields a decrease in the chamber current that is sensed by the electronic circuitry. The drop of current between the plates triggers an alarm.
