Flame Detection GENERAL MONITORS Protection for life. MODELS FL3110/FL3111 UV/IR and UV Unitised Flame Detectors • Wide Field of View • Greater coverage for detecting fires utilising fewer detectors • Status clearly visible from front • Continuous Optical Path Monitoring (COPM) • Checks optical path integrity and detector’s electronic circuitry once every minute • Stainless Steel Construction • High level of corrosion resistance for Marine Environments • EExe Wiring Compartment • Ease of Field Wiring connection • Five Output Configurations • Flexibility of choice and economy of purchase Description General Monitors’ Models FL3110 and FL3111 are UV/IR and UV only flame detectors designed to detect unwanted fires and provide alarm outputs directly from the detector while maintaining false alarm immunity. They complement the existing FL3112 multi-IR detector, completing the "family". The serial communication port(s) allows 128 units (247 using repeaters) to be linked up to a host computer using the MODBUS RTU protocol. The communication registers provide alarm status, fault and other information for operation, trouble shooting or programming the unit. The Model FL3110 detects fires by monitoring in both the ultraviolet and infrared (UV & IR) spectral ranges making it highly immune to false alarms caused by lightning, arc welding, hot objects and other sources of radiation. The Model FL3111 detects in only the ultraviolet (UV) spectral range for optimised speed of response. 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. The detectors’ electronics are integral within an explosionproof 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 Models FL3110 and FL3111 are available in a number of output configurations: • 4-20mA stepped output + single serial communications port • Dual serial communications ports • Warning, alarm and fault relays • Alarm and fault relays with on-board EOL and alarm resistor • 4-20mA stepped output only Applications • Refineries • Drilling and Production Platforms • Fuel Loading Facilities • Compressor Stations • Electrostatic Paint Spray Booths • LNG/LPG Processing and Storage Facilities • Gas Turbines • Chemical Plants • Aircraft Hangars
