Triple Infrared Sensor Flame Detector (IR3) with Zinc Alloy Housing – FF762 Aritech™

General
The FF762 is an IR³ flame detector in a zinc alloy housing.. IR³ sensor models have excellent flame response while providing excellent immunity to foreign IR emission sources. New microprocessor technology makes the detectors highly sensitive allowing them to operate through smoke, of a layer of oil, of dust, or water vapor. Adjustable sensitivity is provided according to EN54-10 standard.

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

Easy installation and maintenance
Units can be wired to 2 threads, 4-20 mA, or via 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 mount or the rain cover. Units are vibration tolerant, and the wind does not affect its operation. The IR³ unit has excellent tolerance for detector window contamination and can detect flame through glass windows. A flame sensor test unit is available for exact testing of detectors.
