Crowcon FGard IR3 flame detector offers first-class flame detection with intelligent heating optics for clearer results and advanced optical verification to greatly reduce false alarms.

I. Specification of Crowcon FGard IR infrared fire detector

Crowcon FGard IR3 offers outstanding performance in the detection of hydrocarbon fires. The FGard IR3 fire alarm uses the latest IR flame detection algorithms to ensure maximum resistance to false alarms.
Crowcon FGard IR3 has been independently tested to prove it can detect hydrocarbon fuel pan flames at nearly 60 meters in less than 5 seconds..

Crowcon FGard IR3 - Multi-spectral IR:

60 meter flame detection range - Crowcon FGard IR3 flame detector will detect all Hydrocarbon fires, improving reliability and performance over temperature.

Crowcon FGard IR3 - Fast detection time:

Short response time in less than 5 seconds 0.1m² flame at 60 meters.

Crowcon FGard IR3 - Thermal optics:

Crowcon FGard IR infrared fire detector with smart heating optics - No condensation / ice / water.

Advanced optical verification - No reflectors:

Crowcon FGard IR3 test automatically verifies the cleanliness of the lens and electronic circuitry. No reflective optical checks and large optical surface resulting in much less false alarms.

II. Advantages

Multi-spectral IR design provides long detection distance and enhanced anti-false alarm Continuous optical inspection, no reflector:

Verify operations and improve device uptime

Microprocessor controlled heating:

Stay operational in extreme weather conditions (snow, ice, condensation)

International hazardous area approval:

FM / ATEX / IEC Ex / INMETRO / PESO

Certified performance test for multiple fuels:

FM 3260
EN 54-10

Sensitivity levels are adjustable:

For flexible application Make sure the detector doesn't cross-vote

External testing with long range flame simulator:

Minimize the need for scaffolding

Easy integration using industry standard output:
