Comparison of Various Types of SharpEye Flame Detector
Each of the Spectrex flame detector families uses one or more of the Ultraviolet (UV) and/or Infrared (IR) techniques. However, each family is recommended only for specific applications, usually determined by evaluating to what extent false alarms could create problems.
| Detector Type | Applications | Advantages | Disadvantages | |
|---|---|---|---|---|
| Triple IR (IR3) | -Hydrocarbon fires -Indoors and outdoors | -Moderate speed -Highest sensitivity -High immunity to false alarms -Longer detection range -Unaffected by solar radiation | - | Affected by IR sources only at short range in certain rare fire scenarios |
| Multi IR | -Hydrocarbon and Hydrogen fires | -As IR3 but with hydrocarbon and | - | As IR3 |
| -Indoors and outdoors | hydrogen fire detection | |||
| Hydrogen (IR3) | -Hydrogen fires only -Indoors and outdoors | -Detects’ invisible’ Hydrogen flames -Longer detection range -High immunity to false alarms -Unaffected by solar radiation | - | Not to be used for Hydrocarbon fire detection |
| -Hydrocarbon fires | -As IR3 but with color video | |||
| CCTV (IR3+Video) | -Indoors and outdoors | -More information & record of the protected area before, during and after fire scenario | - | As IR3 |
| Dual Band UV/IR | -Hydrocarbon, Hydrogen, Silane, Ammonia, other hydrogen-based fuel fires and Metal fires -Indoors and outdoors | -Moderate speed -Moderate sensitivity -Low false alarm rate -Unaffected by solar radiation | -Affected by specific UV//IR ratio created by false stimuli -Blinded by thick smoke, vapors, grease and oil deposits on the detector window | |
| Single I (IR) | -Hydrocarbon fires -Indoors | -Moderate speed -Moderate sensitivity -Unaffected by solar radiation -Low cost | -Subject to false alarms ((in the presence of flickering IR sources) | |
| Single Ultraviolet (UV) | -Hydrocarbon, Hydrogen, Silane, Ammonia, other hydrogen-based fuel fires and Metal fires -Indoors | -High speed -Moderate sensitivity -Unaffected by solar radiation -Unaffected by hot objects -Low cost | -Subject to false alarms from UV sources (arc welding, electrical sparks, halogen lamps) -Blinded by thick smoke, vapors, grease and oil deposits on the detector window |
