How does ionization smoke detector work

WebMar 10, 2024 · Ionization smoke alarms generally perform slightly faster (30-90 seconds) to fast flame fires – fires with flames which spread quickly – than photoelectric alarms. The NFPA acknowledges that a well-designed photoelectric alarm will usually outperform ionization alarms in all fire situations, regardless of type and material. WebSmoke particles disrupt the low, steady electrical current produced by radioactive particles and trigger the detector's alarm. They react quickly to fires that give off little smoke. Ionization smoke detectors expose people to a tiny amount of radiation—about 1/100 of a millirem per year.
