Infra-Red Flame Detection

1 Fire DetectionS131 Solar Blind Flame DetectorInfra-Red Flame DetectionFeaturesCompletely solar blind for use anti static housing to stainless steel 316 mounting sensitivity to hydrocarbon fires in dirtyenvironmentsNot effected by smoke, dust or sensor and unique optical 20mm cable entries for immuntity to external interference fromRFI/EMI use of micropower electronics allows thedetectors to operate in conventional 2 wiredetection in response Certified EEX ia llC T54 spare terminals for connecting spare false alarms from welding, sunlight or highintensity lightsLow maintenance costsQuick response to hydrocarbon firesLong range and Gas Storage and Transfer and Commercial Aircraft Works and and Coal Fired Power StationsGas Turbine Presses and Paper meet the demands of arduous environments, such as chemicalplants and off-shore oil and gas platforms, the s131 detector hasbeen specially packaged in a rough, GRP anti-static housing withabrasion resistant sapphire windows and a rating of IP67 to giveprotection against water ingress under sustained, high wind in the Infra-Red spectrum around microns.

2 Ensuresthat the detector will not be blinded by thick smoke and will betolerant to dirty 20mm cable entries and two 4 way terminal blocks areprovided, which eliminates the need for a local junction box,reducing installation s131 Infra-Red Flame Detector uses the same optical andelectronic module as the S111 and S121 detectors, which havebeen installed worldwide with universal success. It therefore hasidentical performance characteristics making it completely blind tosolar radiation whether direct, reflected or modulated. 26/07/2005 09:05 Page 1 Note: These results are based upon the test fires reaching equilibrium rates of combustion in a still detector is designed to respond in a minimum time of three seconds, this being the signal processing time constant of the sizes of fire will be detected at given distances in the same time and the graph shows the typical ranges for the Detection of theflames.

3 Above given areas of various liquid bracket is manufactured from stainless steel 316 andprovides a degree of horizontal and vertical adjustment whichallows the detector to be positioned to give an accurate cone ofvision of the specific risk rotation 500 Azimuth elevation 700A location template is provided to ensure correct installation ofmounting bolts and the mounting surface must be flat and freefrom adjusted, it is locked in position using two locking boltsensuring a high degree of positional s131 mounting bracket is supplied as a separate componentas detectors are sometimes installed directly onto in Hazardous AreasThe S131detector meets the requirements of EN 50-020 Part 7 and is ATEX Certified EEX ia llC T5.

It will detect a fire at 20m on the centre line, within approximately 10 seconds. A isdetected at 40m. Installation arrangements will be specific to the environment and risk Sensitivity and RangeThe polar diagram shows that the maximum detector sensitivity lies on the detector central axes.

5 The variation of relative ranges withangle of incidence up to the maximum is shown. The range of the detector will vary with the type of fuel as indicated 2: Centre line range against petrol flames Base Area of FlameFigure 5: Relative Range vs Angle of 26/07/2005 09:05 Page 3 The right is reserved to modify or withdraw any product or service without noticeTechnical Information Sheet PSF058U Tyco Safety Products Anti Static BlackDimensions mm:160W x 160L x 90 DWeight (including Bracket) Entry:2 x 20mmMetal Parts (External & Internal)Bright Stainless Steel 316 to BS 1449 pt2 ElectricalSupply to Current:100uA max at 20V dcAlarm Current:60mA maxConnections.
