FL3110 FL3111 FL3112 K ey Features

Only the correct combination and intensityof UV/IR radiation determined by algorithm in the microcontroller can signal an alarm.The unitized FL3102 and FL3112 DigitalFrequency Infrared detectors utilize infrared detectors and Digital Frequency analysis (DFA). The infrared detectors analyzehigh and low frequencies, in addition to comparing flame and reference wavelengths, thus discriminating against false alarms. Associated with the detectorsare flicker discrimination circuits, which are sensitive to flame modulation, including that produced by a large fire. The FL3100 Flame Detector Series is designed with:
?Continuous Optical Path Monitoring checks the optical path integrity once every minute.?Flicker discrimination circuitry reduces the possibility of falsealarms even in the presence ofarc welding,lightning,sunlightor hot objects.?MODBUS RTU CompatibleRS-485 Serial Communication for Easy,Flexible Networking of up to 128 Detectors,or up to 247 detectorswith repeaters.Dual Modbus optional.?4-20mA analog output for remote alarm and fault indication.?Aluminum or Stainless Steel HousingSupports Harsh Conditions and Explosion-Proof Environments. ?Standard Wide Temperature Range -40ËšF to 185ËšF (-40ËšC to 85ËšC)?Special Version of FL3100 for Detection of Hydrogen Fires.?Modular Components Result in Low Maintenance and ReducedTotal Cost of Ownership.

Advanced Flame Detector Design

The FL3100/3101/3110/3111 contain aphototube that responds to radiation in the 185-260 nanometer range. The UV portion of the FL3100 / FL3110 detector is combined with a pyroelectric detector, which responds to a change in the intensity of infrared radiation (4.35 um) achieving a very high degree of discrimination.

System Approvals
