The FlameSpec™ IR3 flame detector provides ultra-fast response, high performance, and reliable detection of all types of hydrocarbon fires (visible and non-visible).
The detector addresses slow-growing fires as well as fast eruptions of fire using improved triple IR (IR3) technology.
The detector operates in all weather and light conditions with the highest immunity to false alarms.
Highest immunity to false alarms.
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 improve false alarm immunity.
Optimized hangar mode option for aircraft hangars, helipads & truck loading racks available, see FLS-IR3-CO2L data sheet.
Ultra-fast detection mode – detection within 40 milliseconds for fireballs or explosions.
Fast flame detection, <1.5 seconds for standard fire up to 30 m. Option for <0.5 seconds, in compliance with NFPA 33, available.
5 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 and 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 for configuration and maintenance (option available).
Window heater to avoid condensation and icing.
Stainless steel tilt mount provides horizontal and vertical adjustment.
Marine approvals - MED & DNV Type approval available on request.
Functional safety - SIL 2 capable (option available).

Where hydrocarbons, confined workspaces, and human activity meet, the risk of fire and explosion is a constant reality.
Reliable detection is your first line of defense, engineered to deliver peak performance even in the most punishing heat and humidity.
Different areas of onshore facilities require tailored detection strategies:
Multiple risk types can be covered by IR3, IR3-H2 or UV-IR detectors. FGD® FlameSpec™ detectors offer high speed detection and industry leading false alarm rejection.
The unique integrated HD video camera offers the operator the chance to analyze and assess before activating shutdown. Additionally vital information can be relayed to first responders for incident management and post event analysis saving thousands on insurance premiums.
Large area coverage and integrated HD video can reduce the device count saving on I/O points and cable. FGD® also offers unique mounting options for floating roof storage tanks
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.
