14、sdealt with.2) They have the form of recommendations for international use and theyare accepted by the National Committees in that sense.3) In order to promote international unification, the IEC expresses thewish that all National Committees should adopt the text of the IECrecommendation for their n

15、ational rules in so far as nationalconditions will permit. Any divergence between the IEC recommendationand the corresponding national rules should, as far as possible, beclearly indicated in the latter.This standard has been prepared by IEC Technical Committee No. 79:Alarm systems.The text of this

16、standard is based on the following documents:Six Months Rule Report on Voting79(CO)24 79(CO)31Full information on the voting for the approval of this standard can befound in the Voting Report indicated in the above table.SANS 60839-2-6:2010This s tandard may only be used and printed by approved subs

18、ors for use in intruder alarm systemsinstalled in buildings. This standard is an addition to the general require ments for detectors for use in intruder alarm systems as specified in IEC839-2-2; it shall also be used in conjunction with the standard for generalrequirements of alarm systems, IEC 839-

19、1-1. The detector may includemore than one sensor, but all sensors shall be in the same housing_The object of this standard is to specify those requirements for passiveinfra-red detectors which will ensure that they will perform satisfactorilyand minimize false alarms.2 Normative referencesThe follo

23、-6 lEe3 Definitions- 9 -For the purpose of this International Standard, the following definitionsapply in addition to those given in the general requi rements.3.1 Passive infra-red detectorA detector which generates an alarm condition in response to a change inthe received level of infra- red radiat

24、ion caused by persons moving in thea rea of detection coverage.3.2 Sensitive sectorsThose sectors in the optical pattern of the detector which detect infra- redradiation.3.3 Area of detection coverageThe area within which a reference target moving at a constant distancefrom the detector will cause a

25、n alarm condition.3.4 Reference targetA device with infra-red emission characteristics similar to those of anaverage person. For the purpose of this standard, this shall take the formshown in figure 1.3.5 Detection rangesThe detection ranges for given directions are the radial distance from thedetec

26、tor to the outer boundary of the area of detection coverage.3.6 Secondary reference targetA device with infra-red emission characteristics similar to those of a smallanimal, such as a rodent. For the purpose of this standard, this shall takethe form of a cylinder 30 mm in diameter and 150 mm in leng

27、th.4 General considerationsThe detector shall consist of one or more sensors and a processor. Whereadditional sensors may be optionally added, the tests required in Clause 6shall be carried out without these additional sensors. The detectors mayhave means incorporated to vary the direction of the se

28、nsitive sectors.These means shall be within the equipment container. Detectors may alsoincorporate means to permit the measurement of the extent of the sensitivesectors, but if these means prevent the detector from meeting the require ments of this standard, an indication shall be given whenever the

29、y are inuse.SANS 60839-2-6:2010This s tandard may only be used and printed by approved subscription and freemailing clients of the SABS .839-2-6 IEC5 Requirements- 11 -5.1.1 Signal processingThe detector shall be capable of detecting the lateral movement of thereference target with respect to the de

30、tector within the area of detectioncoverage at speeds varying from 0,3 mls to 3 mls and shall cause an alarmcondition within 3 m of unidi rectional movement by the reference target, ata constant distance from the detector.5.1.2 Restoration following an alarm conditionFollowing an alarm condition and

31、 the cessation of the movement whichcaused it, the detector shall return to its normal non-alarm conditionwithin 10 s.5.1.3 Resistance to small targetsThe sensitivity of the detector shall be such that an alarm condition shallnot be generated when a secondary reference target is moved on the floorwh

32、en the detector is mounted at the fixing height recommended by themanufacturer.5. 1.4 Resistance to background temperature changesVariations in the background temperature throughout the range +25 c to+40 c, at a rate of 1 C/min, shall not cause an alarm condition.5.1.5 Resistance to vehicle headligh

33、tsThe detector shall not generate an alarm condition as a result of beingilluminated by the equivalent of a vehicle headlight shining through glasswhen tested in accordance with 6.2.5.5.1.6 Resistance to turbulent airTurbulent air above or below the ambient temperature around the detectorshall not c

34、ause an alarm condition when the detector is tested in accord ance with 6.2.6.5. 1. 7 Tamper protectionTamper protection shall be fitted and shall generate an alarm conditionwhen the container is opened sufficiently to give access to any controls ormechanical fixing adjustments.5. 1.8 Cable protecti

35、onWhere a sensor is in a separate housing to the processor, the connectingcable shall be considered to be part of the detector. It shall be electricallymonitored insuch a way that, if the disconnection or short-circuit of anyconductor(s) prevents alarm information or a tamper alarm being receivedby

36、the processor, the processor itself shall generate an alarm conditionwithin 10 s.5.2 EnvironmentalNo additional requirements.SANS 60839-2-6:2010This s tandard may only be used and printed by approved subscription and freemailing clients of the SABS .839-2-6 IEC5.3 SafetyNo additional requirements.5.

37、4 ReliabilityNo additional requirements.5.5 InterfaceNo additional requirements.5.6 ConstructionNo additional requi rements.5.7 Walk-test indicator- 13 -If a walk-test indicator is fitted, it shall be possible to restrict its indi cation without opening the detector.5.8 Manufacturers specificationsI

38、n addition to the information in the general requirements, the manufac turer shall provide the following for each detector:aJ the geometry of sensitive sectors by diagram;bJ area of detection coverage (this may be incorporated in the samediagram as oJ), at each switched sensitivity and pulse-count s

39、etting,where these facilities are provided. If sensitivity is continuouslyvariable, the area of coverage shall be given for maximum and minimumsensitivities;cJ fixing height or range of fixing heights;d J optimum optics setting.5.9 OptionsNo additional requi rements.6. Test procedures6.1 Test condit

40、ionsExperience has shown that it is difficult to achieve repeatable and repro ducible test results using a human target. The following test method,using a simulated target, is therefore proposed as an alternative. Themethod has not yet been practically demonstrated and may therefore besubject to mod

41、ification in the future.For the purpose of functional tests, the detector shall be mounted at theheight recommended by the manufacturer and in accordance with themanufacturers instructions. The optics shall be set to optimum perform ance as indicated by the manufacturer.SANS 60839-2-6:2010This s tan

42、dard may only be used and printed by approved subscription and freemailing clients of the SABS .839-2-6 IEC - 15 -Where a range of fixing heights is given, the tests shall be carried out atthe upper and lower positions.Where pulse-count or sensitivity controls are provided, the tests shalf beca rrie

43、d out at the upper and lower settings of these controls.The reference target shall be mounted with its main axis vertical and itslower edge not more than 100 mm from the floor. Its temperature shall beuniformly distributed, with a total variation from the average temperatureof not more than 0,2 c ac

44、ross its surface.The background within view of the detector shall have the same emissivityas the reference target and its temperature shall be within 20C and25 c, and shall remain constant throughout the tests. Its temperatureshall be uniformly distributed, with a total variation of not more than0,5

45、 c across its surface.The average temperature of the reference target shall be 4 c 0,25 cabove the average background temperature.The tests may be carried out either by fixing the detector and moving thereference target or by fixing the reference target and rotating thedetector. I n either case, the
