Flame Detectors IR + UV
FLV45 FLV45A FLV45A-AL
INFORMAZIONI TECNICHE
TECHNICAL ADVANTAGES
• high speed of intervention
• wide area surveillance
• immunity to false alarms
• possibility of safe operation
in environments with large perturbations
in the visual field
APPLICATIONS
• fire detection in fuel stores (petrol, oil,
kerosene,etc.).
• flammable chemicals
• storage of paints
• storage of paper products
• timber storage
• chemical laboratories
• deposits of flammable gases
The flame detectors FLV-45 are suited for electronic fire
detection systems where the speed response is of primary
importance. They are able to detect the presence of a flame (target
flame - see the technical data below) up to 25 m, easy to install
and are very reliable.
These detectors find particular application in the places where it
is presumed that a fire may develop quickly, such as in warehouses
of petroleum products, paints, plastics, alcohols, etc. The
principle of operation of these detectors is the detection of the
infrared IR and ultraviolet UV components of the flame. The flame
emits a very broad spectrum of radiation ranging from ultraviolet
to infrared range.
The detection of both infrared and ultraviolet components is a
clear evidence of the presence of the flame.
Two special UV and IR sensors, through a suitable window of
vision, “watch “ the supervised area . When inside this is generated
a flame due to start of fire, the IR and UV radiation emitted by
the flame itself, are readily detected by the sensor which , through
appropriate associated electronics, will trigger an output relay
for sending the alarm signal.
The electronic board is accompanied by special algorithms to
give the detector a high immunity to false alarms.
The detector has a sensitivity adjustment independent for the two
channels IR and UV in order to allow a perfect adaptation to the
environmental conditions.
