FL4000 Intelligent MSIR Flame Detection System General Monitors' Model FL4000 is an advanced multi-spectral infrared (MSIR) flame detector designed to provide superior false alarm immunity with the widest field of view. The FL4000 reliably discriminates between actual flames and the vast majority of false alarm sources (such as arc welding or hot objects) by utilizing a multi-spectral optical IR sensing array with a sophisticated Neural Network Technology (NNT) system. The FL4000 detects typical fires such as alcohol, n-heptane, gasoline, jet fuels, and hydrocarbons and can see through dense smoke produced by diesel, rubber, plastics, and lube oil fires. Standard features include: • MSIR sensor array for maximum range of up to 230 ft. • Continuous optical path monitoring (COPM) checks optical path integrity for high reliability • Response time of <10 seconds for rapid flame detection and alarming • Industry standard 4-20 mA output signal for communications with remote alarms, PLCs or DCS • Dual-redundant MODBUS communications via RS-485 interface for remote operation • Explosion-proof stainless steel housing for corrosive and marine environments Contact Freeman Equipment Company Phone: 800-611-1227 or 770-938-1227 • FAX: 770-934-4091 E-mail: sales@freemanequipt.com
