Key Features / Benefits
Excellent Discrimination of False Alarms UV detection in the 185-260 nanometer range which
is well below natural sunlight and artificial light. IR detection at 4.3 microns which is the CO2 spike
generated from hydrocarbon fires.
Flicker discrimination algorithm, which eliminates false alarms from IR sources.
Arc welding and lightning will not cause the FlameGard UV/IR to go to false alarm.
Key Features / Benefits
“COPM” Continuous Optical Path Monitoring We check the optical path once every minute on both
the UV and IR sides to make sure the windows are not dirty, and that the test sources and detectors are working properly.
Wide Angle of View 120° angle of view is the widest in the industry which
allows for a larger area of coverage and a reduced number of detectors.
Key Features / Benefits
Hydrogen Fire Specific Flame Detector Uses a wavelength of 2.7-3.2 microns on
the IR detector to detect the water spike of Hydrogen fires.
Output Capability Three programmable relays (8 AMP)
0-20 mA stepped output to allow quick diagnostics for UV only, IR only, COPM Fault and overall Failures
Modbus for digital communication HART------Digital Communication protocol.
Communicates via analog output line.
