Quizplus · Accepted Answer

The fire detector that responds to an interruption in the light source is known as a photoelectric smoke detector. This type of detector uses a light source and a photoelectric sensor to detect smoke particles. When smoke enters the chamber, it interrupts the light beam, causing the sensor to activate the alarm. Ionization detectors use a radioactive source to ionize the air and detect smoke particles, infrared flame detectors detect the radiant energy emitted by flames, and thermal detectors sense changes in temperature. None of these are specifically designed to respond to interruptions in light sources.
