How does ionization smoke detector work
WebIonization smoke detectors use an ionization chamber and a source of ionizing radiation to detect smoke. This type of smoke detector is more common because it is inexpensive … 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.
