Application Note
FDS303 IR3 Flame Detector is an advanced fire detection solution engineered for rapid and reliable identification of gas fires and liquid fuel fires in hazardous industrial environments. Utilizing multi-spectrum infrared (IR3) technology, it enables long-range detection beyond the visible spectrum while maintaining exceptional immunity to false alarms.
Designed for safety-critical applications, the detector continuously performs optical self-testing without requiring external reflectors, ensuring consistent performance and reduced maintenance requirements. Its microprocessor-controlled heated optics allow reliable operation in extreme environmental conditions, including snow, ice and high humidity.
The FDS303 is certified for use in hazardous areas with FM, ATEX and IECEx approvals and meets stringent performance standards such as FM3260 and EN54-10. It is also SIL 2 capable, making it suitable for high-integrity safety systems in industries where early fire detection is essential.
With flexible integration options including alarm and fault relays, 0-20 mA outputs and HART communication for configuration, the detector can be seamlessly integrated into existing safety and control systems. It also supports external testing using long-range flame simulators, reducing maintenance complexity in large installations.
Widely used across oil and gas facilities, petrochemical plants, power generation units, aircraft hangars, tunnels and storage facilities, the FDS303 IR3 Flame Detector delivers reliable, high-performance fire detection in the most demanding industrial environments.
