C7050 Detector NOTE Not compliant to FM 3260 (2000). SYSTEM APPLICATION The Det-Tronics model R7404 Controller and C7050 Detector provide fast, reliable flame detection in a wide variety of applications. The microprocessor based controller simultaneously monitors up to 16 C7050 ultraviolet (UV) detectors in up to 8 different zones. -

In addition, it is not affected by environmental conditions available from Detector Electronics. such as wind, rain, or extremes of temperature and pressure. The Det-Tronics UV system is also insensitive FEATURES to the ultraviolet component of solar radiation. Considering the above, it can be seen that there are fire • Instantaneous response to ultraviolet radiation. -
