Spectrex Inc. - SharpEyeTM UV/IR (F) Flame Detector Manual – TM756100 Rev A, July 2005 1. Scope 1.1 Product Overview The Flame detector Model 20/20F, with its ultra fast response, is designed to meet the two most important requirements for survivability: Fast Response Time (less than 5 milliseconds) and high reliability (immune to false alarms). The 20/20-F is sensitive to radiation in two frequency ranges of the electromagnetic spectrum: the infrared and the ultraviolet.
Spectrex Inc. - SharpEyeTM UV/IR (F) Flame Detector Manual – TM756100 Rev A, July 2005 2. Technical Description • Detection Range: Up to 20 ft (6m) for a 1ft x 1ft (0.3m x 0.3m) Gasoline fire. • • Ultra High Immunity to False Alarm (see section. 3.3.).
Spectrex Inc. - SharpEyeTM UV/IR (F) Flame Detector Manual – TM756100 Rev A, July 2005 2.3 Detection Levels Simultaneous detection of radiation in both the UV and the IR channels having an intensity, which exceeds detector’s preset Alarm level, will result in an Alarm signal.

Spectrex Inc. - SharpEyeTM UV/IR (F) Flame Detector Manual – TM756100 Rev A, July 2005 3. Performance 3.1 Detection Sensitivity Detection sensitivity is the maximum distance at which the detector will reliably detect a specific size of fire & typical type of fuel (standard fire). Standard Fire: Standard fire is defined as a 1ft x 1ft (0.3m x 0.3m) Gasoline pan fire with max. wind speed of 6.5ft/sec (2m/sec). Detection Range: 20 ft (6 m) from 1ft x 1ft (0.3m x 0.3m) standard gasoline pan fire.
Spectrex Inc. - SharpEyeTM UV/IR (F) Flame Detector Manual – TM756100 Rev A, July 2005 Other Fuels: The Detector will react to other fuels in standard fire conditions at maximum response time of 3 seconds. The sensitivity range to other fuels varies according to the fuel type. Table 1 below provides the sensitivity to other fuels relative to (as a percentage of) the sensitivity to a standard gasoline fire source. Table 1. Response Sensitivity Ranges Type of Fuel % of Max.
