RFD-2FTN-I UV/IR Flame Detector – Product Overview

The RFD-2FTN-I is a highly advanced UV/IR flame detector engineered for critical fire detection in hazardous and industrial environments. This reliable and robust device combines ultraviolet and infrared sensing technologies to accurately detect flames caused by hydrocarbon-based fires, making it suitable for various demanding applications in the oil and gas, petrochemical, chemical, and power generation industries.

1. Advanced Detection Capabilities

At the core of the RFD-2FTN-I lies a dual UV/IR flame detection technology designed for accurate, fast response and minimized false alarms. The detector provides a detection range of up to 30 meters (98.5 feet), ensuring comprehensive coverage of open areas where fires can ignite quickly and pose critical threats.

With a horizontal and vertical field of view of 100°, the RFD-2FTN-I can monitor large zones with a single unit, eliminating the need for multiple detectors and reducing overall installation costs. This wide field of view ensures that even small flames in peripheral areas are detected swiftly and reliably.

The typical response time of 7 seconds allows emergency systems to be triggered rapidly, supporting prompt fire suppression and evacuation protocols to minimize risk to personnel and property.

2. Robust Construction & Environmental Tolerance

The RFD-2FTN-I is built to endure extreme industrial environments. Its enclosure is crafted from high-quality Aluminum 6061, which provides excellent durability and corrosion resistance. With its compact dimensions (64 mm width, 64 mm height, and 75 mm depth) and light weight (just 0.53 kg), the detector is easy to mount and does not add excessive bulk or stress to mounting structures.

One of the most remarkable features of the RFD-2FTN-I is its exceptional operating temperature range, allowing it to function effectively between –40°C and +75°C. This broad range ensures reliable operation in both arctic and desert conditions. Moreover, the device can operate in environments with up to 95% relative humidity, making it suitable for high-moisture areas such as chemical plants, marine facilities, and tropical locations.

The IP66 and IP67 protection ratings further emphasize the detector’s ability to withstand harsh weather, dust, and water ingress, ensuring continuous performance even in the most punishing field conditions.

3. Electrical Specifications for Flexible Integration

The RFD-2FTN-I supports a standard operating voltage of 24 VDC, with a range of 17 VDC to 30 VDC, ensuring compatibility with most industrial power supply systems. It is designed with low power consumption, drawing a maximum of 5.8 watts at 32 VDC, which is beneficial in remote and battery-powered installations.

Output versatility makes the RFD-2FTN-I easy to integrate with fire alarm control panels and safety systems. It offers:

• Relay outputs for Fire, Fault, and Warning alarms.
• 4–20 mA analog output, commonly used for continuous signal transmission in automation systems.
• RS-485 proprietary communication, ideal for long-distance digital data transmission and integration into complex safety networks.

For installation ease, the unit features a 1/2 inch NPT conduit entry size, simplifying cabling and wiring procedures while ensuring secure connections in explosive and hazardous areas.

4. Explosion-Proof and Certified for Hazardous Locations

Safety is paramount in flame detection systems, especially in explosive or combustible environments. The RFD-2FTN-I has been certified by leading international bodies for performance and explosion-proof standards, including:

• FM3260 (Factory Mutual)
• KFI (Korea Fire Institute)
• FM
• CCC (China Compulsory Certification)

In terms of explosion-proof capabilities, the detector meets rigorous global standards such as:

• ATEX and NEPSI certifications (under model RFD-2FTN).
• ATEX Ex db IIC T6 / T5 Gb, indicating flameproof protection in gas groups IIC with temperature classifications T6 or T5.
• ATEX Ex tb IIIC T85°C / T95°C Db, confirming suitability for dust environments with surface temperature limitations of 85°C or 95°C.

These certifications assure users that the RFD-2FTN-I can be confidently installed in Zone 1/21 classified areas, including offshore platforms, oil refineries, LNG terminals, and flammable material storage zones.

5. Reliable Performance Backed by International Standards

The RFD-2FTN-I is designed with global reliability in mind. The combination of UV and IR detection ensures a high level of immunity to false alarms, such as those caused by sunlight, lightning, or arc welding. The detector’s proprietary signal processing algorithms evaluate radiation signatures and make intelligent decisions about flame presence, ensuring only real fire threats are reported.

Its protective ratings (IP66 and IP67) ensure dust-tight sealing and temporary immersion protection, making it ideal for outdoor use in unpredictable weather conditions. These features, combined with the broad operating range and rapid response time, contribute to dependable, uninterrupted operation and longer device lifespan.

Additionally, the detector’s performance adheres to internationally accepted standards, enhancing safety compliance for both end-users and system integrators.
