Dräger Flame 2100

​Working in areas with combustible gases, vapors, or materials requires fire/flame detection as a life-saving necessity. The best solutions must combine state-of-the-art technology with rugged durability and be ready to reliably work in any situation. The Drager Flame 2100 is a single spectrum optical detector using an ultra-violet sensor to detect flames, while eliminating interference from solar-radiation and other non-fire UV sources.

Budget-Friendly and Always Reliable

​The Dräger Flame 2100 uses advanced flame analysis tools to quickly detect a wide number of flames. These include: hydrocarbon- based fuel and gas fires, invisible hydrogen flames, fires from hydrides, ammonia, silane and other organics. Together, with its ability to detect a flash fire in less than 200 msec, nothing remains unnoticed.

Tough and Intelligent

​The Flame 2100 is one of the most weather resistant UV Flame Detectors currently available on the market. It comes with new features such as a heated window to eliminate icing and condensation, HART® capabilities for digital, lower power requirements and a compact, lighter design. The Flame 2100 comes with a built-in test option (BIT).


​Functional safety is a concept applicable across all industry sectors. It is fundamental to enabling complex technology used for safety-related systems. It provides assurance that the safety-related systems will offer the necessary risk reduction. The Dräger Flame 2100 is highly reliable and complies with the IEC 61508 Safety Integrity Requirements of SIL2.

Automatic and manual optics checks (BIT)

​Automatic checks of the detector electronics and optics helps ensure that no fault goes undetected. Additionally, the test can be triggered manually at any time.

Easily visible status LED

​A tri-colored LED, which is visible at the front of the detector, provides a simple status indication to personnel in close proximity to the detector. Green indicates normal operation, yellow indicates a fault, and red indicates the presence of radiation from a fire.

Simple installation and commissioning

​Installation is simple! The detector is easily installed with a stainless steel tilt mount, enabling the detector to be rotated up to 60 degrees in all directions. This offers flexibility in positioning the detector in relation to potential fire sources.

Further benefits and features:

  • ​Solar blind UV spectrum design
  • Fast Response—200 msec response to saturated signal
  • Automatic and Manual Built-In-Test (BIT)—to ensure continued reliable operation

  • 3 Relays for Alarm, Fault, and Auxiliary
  • 0–20 mA (stepped)
  • HART® Protocol for maintenance and asset management
  • RS-485, Modbus compatible
  • Approved to Safety Integrity Level 2 (SIL2—TÜV)
  • Ex approvals for worldwide application: ATEX, IECEx, FM/FMC, CSA
  • 3rd party performance tested: EN54-10 (VdS), FM3260
