FlameGard 5 MSIR
Multi-Spectral IR Flame Detector
Principle of Operation
Reliably detects fires by using several infrared
sensors sampling different IR wavelengths
 Analog signals – Sampled and converted into
digital format for signal pre-processing
 Digital signal – Converted from intensity values
over time to frequency values over time
 A Neural Network algorithm processes values to
identify patterns, which allow it to determine if signals
are from a flame or non-flame source
Flame detection becomes an exercise of pattern recognition,
which is derived from the statistical analysis of data
FlameGard 5 MSIR
Multi-Spectral IR Flame Detector
Artificial Neural Network
Advantages
 Does not depend on developing accurate rules
for classifying flames from false alarms
 Can improve pattern recognition as detector is
“trained” to recognize flame and non-flame events
 Development time shifted to computer optimization

Multi-Spectral IR Flame Detector
Detector Placement
As with other IR flame detectors, the location of the
FlameGard 5 MSIR must be considered carefully:
 Place detector so field of view covers areas where fires may occur1
 Locate detectors at the corners of an area or module1
 Employ CAD tools to optimize area coverage at the design stage1
 Install detectors on the perimeter of equipment under detection,
with an unobstructed line of sight and on rigid mounting points2

FlameGard 5 MSIR
Multi-Spectral IR Flame Detector
Recommended Practices
 Mount units 3 - 5 meters (10 - 15 ft) above the ground
 Tilt instrument down to avoid direct sunlight
 Reduce instrument sensitivity to medium level (34 m; 110 ft
range) in installations where highest range is not needed
 Set delay time to 8 seconds or higher (via dip switch) to
allow discrimination time between flame and false signal
 Configure placement to point detectors in different
directions, but cover the same field of view
 Implement a voting scheme

FlameGard 5 MSIR
Multi-Spectral IR Flame Detector
Test Lamp Check
Independently verify operation of the
FlameGard 5 MSIR
 Using the FlameGard 5 test lamp, self-
sensing test lamp mode
allows remote testing up to 11 meters
Four ways to conduct a test lamp check:
1.
2.
3.
4.
Flashing of the test lamp
Momentary grounding of test wire1
Modbus command
HART command
Regardless of approach used to activate
test mode, each time a FlameGard 5 MSIR
successfully detects the test lamp it
records a time stamp of the event
1
ULC does not approve the grounding of test wire as an option for enabling test mode.

Fault Conditions
 FlameGard 5 MSIR self-diagnostics informs users when
certain types of device failures have occurred
 If a fault is detected, the output signal decreases, the fault
relay de-energizes, one of these fault codes is displayed:

HART
 A configuration of the
FlameGard 5 MSIR is available
with the HART protocol
 Provides uniform and
consistent communication for
all field devices
 Enables continuous, real time
access to diagnostic, process,
and maintenance data
 Because HART requires a
minimum current for operation,
all fault conditions of the
FlameGard 5 MSIR HART
configuration use 1.25 mA as
analog output value
