The FireVu Multi-Detector provides all the same capabilities as the other FireVu detectors with
regards to visual fire detection and also has the ability to detect the presence of heat within the
detector’s field of view by means of its in
-built thermopile sensor.
In addition to the normal visual images the FireVu Multi-Detector produces a thermal image which
over-
laid onto the visual image, the system’s sophisticated software then determines where in the
visual image any heat signatures exist. An absolute threshold for temperature detection can be set
for v
arious areas within the detector’s field of view, which is able to detect temperatures from
-30°C
to +300°C.
The thermal detection capabilities can be configured to be used in one of two ways:
●
As a Double-Knock solution whereby the detector needs to see both a visual indication of
fire and a heat signature in the same area of the detectors field of view.
●
As a stand-alone method of generating an alarm based on an item within the detectors
field of view reaching or exceeding a predetermined absolute temperature threshold. This
can be implemented to detect fire or as a means of process monitoring.
Background and Overview
The processing is completely self-contained within the detector and drives the sensor directly by a
sophisticated sequence of controlled exposures. This allows a direct correlation of Black Body
colours and intensities to reliably determine the presence of a flame.
The Multi-Detector adds a thermal sensing array, providing for sensor determination of absolute
temperature in 0.1 degree Celsius increments for identifying hot areas within an image, for either
an independent thermal threshold, or as further validation of a Flame or Smoke source to qualify
against a maximum threshold.
