IR3

Triple IR Flame Detector

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.

Key Benefits

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.
