WebAug 29, 2024 · An air ionizer is a device that releases negative ions into the air. The negative ions attach to tiny particles, like those in tobacco smoke. This gives the particles an electrical charge,... 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.

WebSmoke alarms are meant to alert you as quickly as possible to a smoke or fire emergency. For example, photoelectric smoke detectors are ideal for detecting smoke from smoldering fires, while ionization smoke alarms detect smoke from fast, flaming fires. WebOne of the most common types is an ionization smoke alarm. Here's how it works: Inside the smoke alarm, there are two tiny metal plates called elec- trodes that are connected to a battery. This is called a circuit. There is also a substance called Americium-241. Americium-241 converts air mola:ules into positive and negative ions.
