Ultraviolet/Infrared Flame Detector (UV/IR Flame Detector) MC.UV/IR-200A Series
MC.UV/IR-200A
UV/IR detectors use a UV sensor along with an IR sensor in one device. This dual-spectrum detector is sensitive to both UV and IR radiation emitted by flames. The UV/IR combination flame detector offers greater safety than single-spectrum detectors, which have a moderate response speed. UV/IR flame detectors are suitable for indoor and outdoor use and detect a wide range of hydrocarbon flames such as wood, paper, gasoline, as well as hydrogen and hydrocarbons such as methanol and methane.

Advantages and disadvantages
Advantages:
- Insensitivity to sunlight reflection.
- Responds to a wider range of fires than UV detectors.
- Insensitivity to artificial lights, such as fluorescent lamps, halogen lamps, etc.
- Separation, analysis and decomposition of flame radiation wavelength to reduce false alarms.
- Possibility of using UV or IR mode alone by changing the settings on the device.
- UV/IR detectors are not suitable for smoke-producing fires.
- Steam, smoke, oily contaminants and certain gases reduce the sensitivity and performance of the device.
- It has a medium response time compared to UV detectors due to dual UV and IR processing.
