IR3-CO2L


Triple IR Flame Detector

 

The FlameSpec™ IR3-CO2L  flame detector has been optimized to provide a fast, robust detection of a wide range of heavy hydrocarbon fires, where combustion exhaust gases may be present, and standard IR3 detectors might false alarm.

Typical applications include: Aircraft hangars, hardened aircraft shelters, helipads (onshore, offshore, and hospitals).

Areas with high vehicle activity: Waste recycling facilities - Road / Rail tanker loading racks.

 

 

Key Benefits

  • Highest levels of false alarm immunity.

  • Detects up to 262 ft (80 m) for a 1 ft2 (0.1 m2) n-heptane pan fire.

  • Hydrocarbon flame detection: Three wavelengths in the infrared spectral range of 4.0 to 5.0 μm with clear separation.

  • Each sensor has the same field of view to further improve false alarm immunity.

  • Ultra-fast detection mode – detection within 40 milliseconds for fireballs or explosions.

  • Fast flame detection, <1.5 s for standard fire up to 100 ft (30 m).

  • Five selectable sensitivity levels.

  • Universal outputs, 3- and 4- wire, 4—20 mA sink / source, Fire, Auxiliary, and Fault relays. RS485 port using Modbus RTU.

  • Event logger – alarms & faults are logged to non-volatile memory.

  • Built-In-Test (BIT) – Automatic and manual self-test of window cleanliness and overall detector operation.

  • Dirty optics warning for preventive maintenance needs.

  • HART® 7 as standard. Enhanced configuration and maintenance.

  • Window heater to avoid condensation and icing.

  • Stainless steel tilt mount provides horizontal and vertical adjustment.

  • Functional safety - SIL 2 capable.

High-Value Asset Coverage

 

Precision Detection for High-Value Aerospace Assets

 

Maintenance and refueling zones are complex environments where safety cannot be compromised. We address the unique challenges of the hangar:

  • The Risk: Low-frequency but high-consequence fire events fueled by hydrocarbons.

  • The Interference: Constant "noise" from diesel vehicles, engine exhaust, and maintenance work (welding/sanding).

  • The Solution: Advanced spectral analysis that distinguishes between a fire and a false alarm, protecting your airframes from both fire and accidental foam damage.

Application Challenges

 

Cover a large area with reliable flame detection and no false alarms

 

  • Large area coverage
  • Detection both above and below the wings
  • Highest possible false alarm rejection capability
  • Correct mapping of detector coverage to fire zones
  • Access to the detectors for maintenance
  • Detectors must be self-testing to ensure reliability

Detection Strategy & Zone Types


Detection strategy based on detection and fire zone coverage both above and below the wings and body of the aircraft.


Different areas of aircraft facilities require tailored detection strategies:

Maintenance & Storage Hangars

 

Utilize IR3-CO2L flame detector with integrated video camera for high-speed detection and maximum false alarm rejection. The Hangars require large area coverage that can be matched to suppression zones. With five sensitivity settings and the unique FlameView accessory, the FlameSpec™ range of detectors can be set to provide large-area coverage that meets the requirements for suppression.

Fueling Areas

 

Depending on the operation different fuel types may be used where the detection ranges can vary. It is critical that flame detectors are selected based on their ability to provide coverage regardless of fuel or risk. Third-party testing according to FM 3260 confirms FGD detectors' ability not only to detect but gives the fire size and detection range in feet and meters.

Hardened Aircraft Shelters

 

Operational areas where exhaust from jet engines is a regular false alarm risk. FGD® FlameSpec™ CO2L detectors have been rigorously tested in real environments for their ability to operate continuously even when exposed to military aircraft jets entering, shutting down, and starting up in Hardened Aircraft Shelters (HAS).

Key Certifications

 

The FlameSpec™ range is rigorously tested and certified to meet global safety, performance, and reliability standards.

Its comprehensive range of certifications ensures compliance with international regulations for hazardous environments, making it a trusted solution for high-stakes applications. From explosion-proof approvals to functional safety and ingress protection, these certifications validate the detector's ability to perform under the most demanding industrial conditions.

  • ATEX / IECEx Zone 1 and 2 certified, cFMu Class 1 Div 1

  • FM3260 and EN54-10, performance approval

  • NFPA 409 Annex C
