Spectrex flame detector are flame monitors from tens to hundreds of meters away. The device uses the principle of infrared IR, and/or ultraviolet UV to detect the presence of a flame. The fire detection sensor part is usually installed in the field, the warning signal is transmitted to the center. In some configurations, the detector is also integrated with a Camera to have a visual image of the monitored area. The remote fire alarm system is quite expensive, so it is mainly applied in important fields such as marine, oil and gas, important industrial plants.
