General Monitors’ Model FL3111HT is a high-temperature-rated UV-only flame detector designed to detect unwanted fires while maintaining false alarm immunity. The FL3111HT detects only in the ultraviolet (UV) spectral range for optimised speed of response.
The detector can withstand ambient temperatures of up to 125 °C. This is achieved by using a specially selected detector and electronic components, along with very low power consumption, to minimise self-heating.
The detector’s electronics are integral within an 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. The FL3111HT is available with a 4-20 mA stepped output.
The COPM (Continuous Optical Path Monitoring) self-test feature checks the optical path integrity (window cleanliness) and the detector’s electronic circuitry once every minute.
