FL3111HT High Temperature UV Flame Detector (EU)

The FL3111HT is a high temperature rated (125°C) ultraviolet (UV) optical flame detector designed to detect unwanted fires while maintaining false alarm immunity. The FL3111HT detects only in the UV spectral range for optimized speed of response. The FL3111HT's electronics are integral within its stainless steel explosion-proof housing, allowing detector information to be processed at the point of detection. The electronics are fully separated from the Exe wire compartment offering protection during installation and service.
