Which of the following detection devices measures light waves associated with high-intensity flames and sounds an alarm when such waves are detected?

Which of the following detection devices measures light waves associated with high-intensity flames and sounds an alarm when such waves are detected?

• A. Smoke detector
• B. Heat detector
• C. Flame detector
• D. CO detector

Answer: (C)

Flame detection devices are specifically designed to identify the presence of flames through the measurement of light waves emitted by high-intensity fire events. These devices utilize sensors that are sensitive to the wavelengths of light typically produced by combustion processes, particularly at the ultraviolet and infrared spectrum. When these sensors detect a significant increase in these specific light waves, indicating a flame, the device promptly activates an alarm, alerting occupants or initiating safety protocols. In contrast, smoke detectors function by sensing particulate matter from smoke, while heat detectors respond to changes in temperature associated with fire. Carbon monoxide detectors monitor levels of carbon monoxide gas, a byproduct of combustion, but do not specifically detect flames. This distinction highlights the specialized function of flame detectors in fire protection systems.
