Description

DF-TV7 IR3 Fixed Flame Detector

The DF-TV7 IR3 Fixed Flame Detector is a multi-spectrum infrared flame detector that utilises three individual wavelengths to detect hydrocarbon fires. This flame detector will respond to unwanted hydrocarbon fires while maintaining a high degree of false alarm immunity.

This Fixed Flame Detector is equipped with an intelligent optical self-test function that periodically checks the detector’s optics for any obstructions or contamination.

The Flame Detector offers a wide range of output options as standard, including:

  • 4-20mA loop signal (active type, max. load impedance 700Ω)
  • Relay outputs
  • HART communication capability

Call our team for further information at 02920 759 683, or visit our contact page.

Technical Specification
FAQs
How quickly does the detector become operational after power-up?

The detector has a start-up time of 15 seconds, allowing it to begin monitoring for flames shortly after power is applied.

Does the detector require regular maintenance or calibration?

The detector features an automatic periodic self-test through the viewing window and is factory calibrated, meaning no field recalibration is required under normal operating conditions.

What output signals are available for integration with control systems?

The detector supports:

  • 4–20 mA active loop output (source type)
  • Configurable fault and alarm current levels
  • Three configurable relay outputs rated up to 1.7 A at 30 VAC/DC

These outputs make the detector compatible with PLCs and modern fire and gas control systems.

Is the detector suitable for harsh industrial and hazardous environments?

Yes. The detector is designed for demanding environments and offers:

  • IP66 protection rating
  • Operating temperature range of -40°C to +65°C
  • 95% RH non-condensing humidity tolerance
  • 316L stainless steel housing
