4040 UFI Ultra Fast Triple IR IR3 Flame Detector 05296

The 40/40UFI, an Ultra-Fast multispectrum IR3 Flame Detector, detects hydrocarbon fuel and gas fires at long distances, and is especially designed to detect an explosive 1 ft (0.3m) diameter gas cloud explosion in max. 50 msecs for 1ft diameter sphere methane-air mixture explosion at 66 ft (20m) with the highest immunity to false alarms. The 40/40UFI IR3 can also detect a 1 ft2 (0.1m2) gasoline/n-Heptane pan fire at up to 300 ft (90m).

The 40/40UFI is part of the 40/40 Series, the most durable and weather resistant range of flame detectors currently on the market. Features include a heated window, to eliminate condensation and icing; HART capability for digital communications; lower power requirements; and a compact, lighter design. Due to increased reliability, the 40/40 Series warranty period has been extended to 5 years and is SIL2 (TUV) approved per IEC 61508.

• Multi Spectrum Design - for long distance detection and high false alarm immunity
• High Speed Response - 50 msec
• Sensitivity Selection - to ensure no zone crossover detection
• Automatic Built-In-Test (BIT) - to assure continued reliable operation
• Heated window - for operation in harsh weather conditions (snow, ice, condensation)
• Multiple output options for maximum flexibility and compatibility
  - Relays (3) for Alarm, Fault and Auxiliary
  - Analogue output for fast detection
  - 0-20mA (stepped)
  - HART Protocol for maintenance and asset management
  - RS-485, Modbus Compatible
• High Reliability - MTBF - minimum 150,000 hours
• Safety Integrity Level SIL2 (TUV)
• 5-Year WarrantyUser Programmable via HART or RS-485
• Hazardous area zones:
  - Zones 1 & 2 with IIC gas group vapors present
  - Zones 21 & 22 with IIIC dust type present
• Ex approved to:
  - ATEX & IECEx
  - FM/FMC/CSA
  - TR CU (EAC)
• 3rd party Performance
  - EN54-10 (VdS)
  - FM3260 (FM)
