Double détecteur de flamme IR Intrinsèque dans un boîtier en alliage de zinc moulé Talentum-16571
Talentum-16571 - Double détecteur de flamme IR Intrinsèque dans un boîtier en alliage de zinc - FFE
The Talentum 16571 is a intrinsic safe IR² flame detector in a die-cast zinc alloy housing. IR² models have execellent response to flame while providing 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 IR² 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 1.0 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 IR² 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.
