F-Guard IR3 CO2L
Triple IR Flame Detector. The FlameSpec IR3 will detect fires and explosions extremely quickly, thereby allowing mitigation steps to be initiated more rapidly to limit event escalation.
List of Benefits
- Highest levels of false alarm immunity.
- Detects up to 262 ft. (80m) for a 1 ft2 (0.1m2) 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 30 m. Option for <0.5s, 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 & 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 & maintenance.
- Window heater to avoid condensation and icing.
- Stainless steel tilt mount provides horizontal and vertical adjustment.
- SIL 2 compliant - suitable for use as part of a SIL 2 compliant safety system.
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,Hospitals)
- Areas with high vehicle activity:
- Waste recycling facilities
- Road / Rail tanker loading racks
