The FlameSpec™ UV-IR-F flame detector provides ultra-fast response, high performance, and reliable detection of a large variety of fires including hydrocarbon fires (visible and non-visible).
The detector addresses slow-growing fires as well as fast eruptions of fire using improved UV-IR technology.
The detector operates in all weather and light conditions.
High immunity to false alarms.
High sensitivity – up to 100 ft (30 m) for a 1 ft2 (0.1 m2) n-heptane pan fire.
Hydrocarbon flame detection. Spectrum response of IR radiation in the 4.0—5.0 micron range.
Ultra-fast detection mode detection within 5 milliseconds for fireballs or explosions.
High-speed (<0.5 s) model [X5] available for compliance with NFPA 33.
Four 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 and other relevant events 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, for configuration & maintenance (option available).
Window heater to avoid condensation and icing.
Stainless steel tilt mount with horizontal and vertical adjustment.
Functional safety - SIL 2 capable - option available.
Detect high UV (sparks and arcs) or IR levels via auxiliary relay and 4-20 mA.

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.
Different areas of aircraft facilities require tailored detection strategies:
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.
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.
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).
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.
