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. WebSep 17, 2024 · Ionization smoke detectors respond faster to smoke from flaming fires than a photoelectric device does. Most flaming, fast-moving fires are a result flammable liquids, wood, or paper catching fire. These …

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. WebScore: 4.9/5 (38 votes) . How they work: Ionization-type smoke alarms have a small amount of radioactive material between two electrically charged plates, which ionizes the air and causes current to flow between the plates.When smoke enters the chamber, it disrupts the flow of ions, thus reducing the flow of current and activating the alarm.
