General Monitors FL4000H Multi-Spectrum IR Flame Detector
The FL4000H is obsolete and has been replaced by the FL5000 flame detector.
The General Monitors FL4000H is an advanced multi-spectrum flame detector designed to provide superior false alarm immunity with the widest field of view. The FL4000H employs a state-of-the-art multi-spectrum infrared (MSIR) sensor array with a sophisticated Neural Network Technology (NNT) system.
The FL4000H is designed to detect typical fires such as those produced by alcohol, n-heptane, gasoline, jet fuels and hydrocarbons. In addition, the FL4000H can see through dense smoke produced by diesel, rubber, plastics, lube oil, and crude oil fires.
The NNT flame discrimination algorithm classifies the output signals from the MSIR sensor array as either fire or non-fire. The MSIR/NNT combination is highly immune to false alarms caused by lightning, arc welding, hot objects, and other sources of radiation.
The FL4000H’s electronics are housed in a stainless steel explosion-proof enclosure. The detector is available with the following output configurations:
- 4-20 mA stepped output
- Dual serial communications
- HART communication
- Warning, alarm and fault relays
The serial communication port(s) allow 128 units (247 using repeaters) to be linked to a host computer using the Modbus RTU protocol. The communication registers provide alarm status, fault information, and other details for operating, troubleshooting, or programming the unit.
The COPM (Continuous Optical Path Monitoring) self-test checks optical path integrity (window cleanliness) and the detector’s electronic circuitry every two minutes.
Features
- Neural Network Technology (NNT) offers superior false alarm immunity.
- Continuous Optical Path Monitoring (COPM) checks optical path integrity and the detector’s electronic circuitry.
- Event logging for a stand-alone diagnostic tool.
- Test mode (with test lamp) is used to check all outputs.
