Smoke alarms photoelectric vs ionization
Did you know?
Web25 Dec 2024 · Ionization smoke detectors, also called ionization-type smoke alarms, are usually characterized by way of a small quantity of radioactive fabric inside the device. This radioactive material ionizes the air inside the sensing chamber and makes it conductive, consequently facilitating modern-day drift between the 2 charged electrodes gift within. Web13 Jan 2024 · Photoelectric smoke detectors operate with a continuous, focused beam of light onto a mirror from an LED light source that is aimed directly into a sensing chamber, away from the sensor. If smoke enters the chamber, the light that is reflected onto the light sensor is interrupted, scattering light in many directions and triggers the alarm.
