Triple détecteur de flamme IR Eexd IIC T6 boitier antidéflagrant Talentum-16519
Talentum-16519 - Triple détecteur de flamme IR Eexd IIC T6 boitier antidéflagrant - FFE
The Talentum 16519 The FF766 is a IR³ flame detector in a flame proof housing. IR³ models have execellent response to flame while providing superb immunity to extraneous sources. New micro-processor technology makes the detectors independent of flame intensity enabling it to operate through smoke, a layer of oil, dust, or water vapor. A high and low sensitivity setting according to EN54-10 is provided.
Installer and maintenance friendly
The units can be wired as conventional 2 wire, 4-20 mA, or relay contacts (fire, fault and pre alarm) in latching or non-latching operation.
Remote test inputs are available to activate self-test.
A stainless steel adjustable bracket and weather shield is also available.
The units are tolerant to vibration, and wind does not affect the performance. The IR³ unit has excellent tolerance to detector window contamination and can detect flame through glass windows.
A flame sensor test unit is available for accurate testing of the detectors.
Reducing false alarms
Most IR flame sensors respond to 4.3µm light, emitted by hydrocarbon flames. By responding to 0.75 to 2.7µm light emitted by every fire, all flickering flames can be detected. Gas fires not visible to the naked eye e.g. hydrogen may also be detected.
The IR³ detectors, responding to adjacent IR wavelengths, enable it to discriminate between flames and spurious sources of IR radiation.
The combination of filters and signal processing allows the sensor to be used without risk of false alarms in difficult situations characterised by factors such as flickering sunlight.
