How does ionization smoke detector work
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. WebGenerally, ionization detectors are more responsive to flaming fires. The term “flaming” fires refers to fires resulting from flammable liquids, wood or paper starting on fire. This type …

WebFeb 11, 2024 · Ionization The first type is Ionization-type smoke detectors. These smoke detectors work by having two plates that each produce either negative or positive ions. These ions then traverse between the two plates, and this creates a complete circuit. WebApr 29, 2024 · Americium-21 is the radioactive material that passes between the electrodes and transforms the air molecules into positive and negative ions. These charged ions complete a circuit and current flows. As a result, the smoke detector works according to its intended procedure. During a fire, smoke enters the detector.
