Flame detector with FF766 triple infrared sensor

The FF766 is an IR3 flame detector in a fire-resistant cover. MODELS with IR3 sensor have excellent flame response while providing excellent immunity to strange IR emission sources. The new microprocessor technology makes the detectors highly sensitive allowing it to operate through smoke, a layer of oil, dust, or water vapour. Adjustable sensitivity is provided according to EN54-10.


Maintenance and installation of the Flame Detector with FF766 triple infrared sensor

The units can be wired at 2 wires, 4-20 mA, or through the relay contacts (fire, fault and pre-alarm) with or without interlocking. Incorporates inputs for remote activation of the self-test. Various accessories are available such as the swivel bracket or rain protector. The units are vibration tolerant, and the wind does not affect their operation. The IR3 unit has an excellent tolerance against contamination of the detector window and can detect the flame through the glass windows. A flame sensor test unit is available for accurate detector testing.


How to reduce the risk of false FF766 alarms?

Most IR flame sensors respond to up to a wavelength of 4.3om, emitted by hydrocarbon flames. Also responding to a wavelength ranging from 0.75 to 2.7om emitted by all types of fire, all flames ranging from those values can be detected. Gas fires not visible by the human eye such as hydrogen can be detected. IR3 detectors, responding to adjacent IR wavelengths, allow you to discriminate between flames and false sources of IR radiation. The combination of filters with signal processing allows thesensor to be used without the risk of false alarms in difficult situations, characterized by factors such as fluctuating sunlight.
