Ultraviolet/Infrared Flame Optical Detector (UV/IR Flame Optical Detector) MA.UV/IR-300A Series
MA.UV/IR-300A
UV/IR detectors utilize 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.
- Distinction, analysis of flame radiation wavelength to reduce false alarms.
- Ability to use 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 moderate response time compared to UV detectors due to the dual UV and IR processing.
