The Tyco 601F is a conventional point type solar blind Flame Detector. The Tyco 601F can be used to protect large open areas without sacrificing the speed of response to flaming fires. For full coverage, the Tyco 601F requires direct line of sight to all parts of the protected area. The Tyco 601F is designed to respond rapidly to fires that involve clean burning fuels such as alcohol or methane, i.e. fires that would not be detected by Smoke Detectors.
