14、sus of opinion on the subjectsdealt 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
15、IECrecommendation for their national rules in so far as national condi tions will permit. Any divergence between the IEC recommendation andthe corresponding national rules should, as far as possible, be clearlyindicated in the latter.PREFACEThis standard has been prepared by IEC Technical Committee

ScopeThis International Standard gives the specific requi rements and testp
18、rocedures for microwave Doppler detectors for use in intruder alarmsystems installed in buildings.This standard is an addition to the general requirements for detec tors for use in intruder alarm systems as specified in IEC Publi cation 839-2-2, and it shall also be used in conjunction with thestand
19、ard for general requirements for alarm systems, IEC Publica tion 839-1-1.The object of this standard is to specify those requirements formicrowave Doppler detectors which will ensure that they will performsatisfactorily and minimize false alarms.2.

Definitions- 9 -For the pu rpose of this standard the following definitions apply inaddition to those given in the general requi rements.3. 1 Microwave Doppler detectorA detector which generates an alarm condition in response to thefrequency shift of the ref
24、lection of microwave radiation from a movingperson.3.2 SensorThe transmitting and receiving elements of the detector.3.3 Microwave radiationElectromagnetic radiation with a frequency above 1 GHz.3.4 Reference targetA person weighing between 50 kg and 70 kg and between 165 cm and180 cm in height, wea
25、ring a cotton overall.3.5 Boundary of detection coverageThe furthest radial distances in all directions at which a referencetarget moving towards the detector will generate an alarm condition.3.6 Detection rangesThe detection ranges for given directions are the radial distancesfrom the detector to t
26、he boundary of detection coverage.4. General considerationsThe detector shall consist of one or more sensors and a processor.Each sensor shall be contained in one housing which may also includethe processor. Where facilities are included to permit more than onesensor to be connected to the processor
27、, the tests required underClause 6 shall be carried out with one sensor only.The detectors may have means incorporated to vary the shape of theboundary of coverage. Where such means are incorporated the testsrequired under Clause 6 shall be carried out with the normal equip ment and setting but addi
28、tional tests shall be carried out to prove themanufacturers claims for the effects of these means.SANS 60839-2-5:2010This s tandard may only be used and printed by approved subscription and freemailing clients of the SABS .839-2-5 IEC5. Requirements5. 1 Functional5.1.1 Frequency- 11 -The operating f
29、requency of the detector shall be not less than1 GHz.5. 1.2 Boundary of detection coverageThe boundary of detection coverage achieved for any detector atmaximum range setting shall be at least equal to but not more than 25%greater than that given in the manufacturers specification.5.1.3 Signal proce
30、ssingThe detector shall generate an alarm condition as a result of thereference target moving towards the detector and within the boundaryof detection coverage for a distance of 3 m or 30% of the initialseparation, whichever is less. Movements of less than 0,2 m shall notcause an alarm condition.5.1
31、.4 Restoration following an alarm conditionFollowing an alarm condition and the cessation of the movement whichcaused it, the detector shall restore to its normal non-alarm conditionwithin 10 s.5. 1 . 5 Intermlttent movementThe detector shall be capable of detecting intermittent movement ofthe refer
32、ence target towards the detector with periods of movementwithin the detectable speed range of not less than 1 s and periods ofno movement not more than 5 s. An alarm condition shall occur withina distance of 5 m or 50% of the initial separation, whichever is less.5.1.6 Detectable speeds rangeThe det
33、ector shall be capable of detecting movement of the referencetarget in the direction of the detector at any speed from 0,3 to 3 m/s.5. 1.7 StabilityThe range of the detector .shall not vary by more than 10% duringseven days of normal operation at a constant environment.5. 1 .8 Tamper protectionTampe
34、r protection shall be fitted and shall generate an alarm condi tion whenever the container is opened sufficiently to give access toany controls or mechanical fixing.SANS 60839-2-5:2010This s tandard may only be used and printed by approved subscription and freemailing clients of the SABS .839-2-5 IE
35、C5. 1 .9 Cable protection- 13 -Where a sensor and its processor are not located in the samehousing, the cable connecting them shall be considered to be part ofthe detector. It shall be electrically monitored so that if a discon nection or short circuit of any conductors prevents alarm informationor

38、tion 839-2-2the manufacturer shall provide the following for each detector:aJ the boundary of detection coverage in the horizontal and verticalplanes for a speed of 1 mls measured as determined by the testgiven in Sub-clause 6.2.1. This may be provided in the form of apolar diagram;bJ the operating
39、frequency and, if any, the frequency and type ofmodulation;c) the detectable speed range if greater than that required bySub-clause 5.1.6.5.9 OptionsMeans may be provided to reduce the radiation of the detector whenits associated system is unset.SANS 60839-2-5:2010This s tandard may only be used and

If these means are incorporatedwithin the detector there shall be an output available to the alarmsystem to
41、 indicate that the radiation is reduced.This output may take the form of an alarm condition.6. Testprocedures6. 1 Test conditionsThe tests shall be carried out in an area with a solid floor wheresurrounding structures do not affect the measured ranges by morethan 5%.The detector under test shall be
42、mounted at the height recommendedby the manufacturer and in accordance with the manufacturers in structions. Where a range of fixing heights is given, the tests shall becarried out at the upper and lower limits.The tests shall be carried out within the standard environmentalconditions for testing gi
43、ven in IEC Publication 68-1.6.2 Functional tests6.2. 1 Boundary of detection coverageThe reference target shall move towards the detector from beyondthe maximum range at a speed of approximately 1 m/s. The distancefrom the detector shall be measu red when an alarm condition occu rs. Itshall be at le
44、ast equal to but not more than 25% greater than thatgiven in the manufacturers specifications. The test shall be carriedout in at least seven uniformly spaced directions in both the horizontaland vertical planes. The vertical plane tests shall be carried out byturning the detector through 90 on the
45、radiation axis.6.2.2 Response at constant speedThe reference target shall move towards the detector from directly infront of it at the boundary of detection coverage at a speed ofapproximately 1 m/s. An alarm condition shall not occur for a move ment of less than 0,2 m but shall occur within a dista
46、nce of 3 m or 30%of the radial separation, whichever is less.The test shall be carried out at speeds of approximately 0,3, 1 and3 mis, and the highest and lowest speed if the manufacturer specifiesa wider speed range.6.2.3 Restoration following an alarm conditionThe reference target shall move towar
47、ds the detector from directly infront of it at the boundary of detection coverage at a speed ofapproximately 1 m/s. The distance from the detector where the alarmcondition occurs shall be noted.

After a fu rther
49、10 s the referencetarget shall move towards the detector at approximately 1 mls and thedistance from the. detector where the alarm condition occurs shall notvary from that found on the first part of this test by more than 10%.6.2.4 Response to intermittent movementThe reference target shall move towards the detector from directlyin front of it at the boundary of detection coverage for a distance of1 m within 1 s and then stop for 5 s and then repeat the cycle. Thedetector shall generate an alarm condition before it moves 5 m or 50%of the separation, whiche
