Question:medium
These systems monitor the production of certain spectrums of light produced by fire, one of these systems monitors infrared light while others monitor ultraviolet light produced by the fire. Identify the type of detector.

Show Hint
Flame detectors = detect light from flames; smoke detectors = detect particles.

- Light Emission Diode
- Heat Detector
- Smoke Detector
- Flame Detector
Show Solution
The Correct Option is D
Solution and Explanation
Flame detectors operate by identifying light emitted by flames. They can detect ultraviolet (UV) or infrared (IR) radiation from combustion. Light Emission Diode (LED) is a light emitter, not a sensor. Heat detectors react to temperature fluctuations, not light. Smoke detectors sense airborne particles, not light spectra. Consequently, the accurate choice is Flame Detector.
