F4-2V, F4-2B, F4-4V, and F4-4B UV/IR Dual Sensor
The UV/IR Radiation Flame Detector is a dual spectrum optical detector
sensitive to two separate ranges of the radiation spectrum, both of which
are present in fires. The detector monitors the protected volume, by
measuring the radiation intensity in it, within two frequency ranges of the
electromagnetic spectrum, namely the Ultra-Violet (UV) and the Infra-Red
(IR).
The detector integrates two dependent channels in which appropriate
detection pulses are registered and further analyzed for frequency, intensity
and duration.
F4-MM Multi IR Sensor
The MultiFlame Multi IR detector is designed to detect hydrocarbon flames
that produce CO
2
in their combustion process and non-hydrocarbon flames
that produce mainly water vapor (H
2
O) from inorganic fuels, for example,
hydrogen, ammonia, hydrofluoric acid, hydrochloric acid and so on.
The detector's principle of operation is based on the patented spectral
analysis technology that identifies the IR spectral signature of fire products,
namely the hot CO
2
spectral emission band at 4.2-4.7 microns and the hot
water (H
2
O) spectral emission band at 2.7-3.0 microns. Additional spectral
bands (above and below these bands) are analyzed for background
interferences.
The spectral analysis incorporates several detection algorithms, according to
several types of fire events, taking into account simultaneous detection of
both CO
2
and H
2
O peaks, or only one of them, as well as flickering analysis
at frequencies typical to these flames. Only when all the parameters of the
spectral analysis and the flickering analysis meet the predetermined values,
is a fire condition identified and the fire alarm is issued.
When exposed to non-fire radiation sources, these parameters do not
identify a fire condition and the detector does not react.
F4-UF UV/IR Flame Detector
The UV/IR Radiation Flame Detector is a dual spectrum optical detector
sensitive to two separate ranges of the radiation spectrum, both of which
are present in fires. The detector monitors the protected volume, by
measuring the radiation intensity in it, within two frequency ranges of the
electromagnetic spectrum, namely the Ultra-Violet (UV) and the Infra-Red
(IR).
The detector integrates two dependent channels in which appropriate
detection pulses are registered and further analyzed for frequency, intensity
and duration.
