This document is bound to be used in conjunction wi

23、th the other parts of the EN 50131 series that define the functional requirements of the equipment regardless of the type of interconnections used. EN 50131-5 is currently composed with the following parts: CLC/FprTS 50131-5-1 Alarm systems Intrusion systems Part 5-1: Interconnections Requirements f

24、or wired Interconnection for I EN 50131-5-3, Alarm systems Intrusion systems Part 5-3: Requirements for interconnections equipment using radio frequency techniques; CLC/TS 50131-5-4, Alarm systems Intrusion and hold-up systems Part 5-4: System compatibility testing for I WD; RE; SPT. Each of the int

25、erference signals defined below shall be applied and shall not cause false alarm, indications of a failure of periodic communication and shall not compromise the correct reception and processing of the messages. During continuous application of the interfering signals whose levels are defined in the

26、 subsequent subclauses, all of the 20 system relevant messages (sent by the transmitting equipment used for test purposes) shall be correctly received and processed by the receiving equipment. In the event of the receiving equipment operating in more than one assigned band, the requirement shall be

27、fulfilled for each individual assigned band. 4.5.2 Interference outside the assigned band for equipment of all grades The receiving equipment shall be fully functional during the application of the interference signal at a level of 10 V/m at frequency F1 and subsequently at frequency F2 (F1 and F2 a

28、re defined in 5.5.1). 4.5.3 Interference within the assigned band for equipment of all grades The receiving equipment shall be fully functional during the application of the interference signal at a level of RL + 8 dB (RL is defined in 5.1) at frequency Ft (Ft is defined in 5.5.1). 4.5.4 Interferenc

29、e within the assigned band for grade 3 and grade 4 equipment Additionally, the receiving equipment shall be fully functional when an interference signal is applied to each assigned band sequentially at a level, IL + 3 dB (IL is defined in 5.5.4) with a frequency modulated signal as defined in 5.5.4.

30、 BS EN 50131-5-3:2017EN 50131-5-3:2017 10 4.6 Requirement for RF links monitoring 4.6.1 General The RF links shall be monitored in accordance with the grade. The indication or notification related to RF link monitoring is dependent on the grade and the state of the equipment. 4.6.2 Requirement for t

31、he detection of a failure of periodic communication A failure of periodic communication shall be detected for any type of device within the time periods as specified in EN 50131-1:2006, subclause relating to Verification of periodic communication. In the case of a failure of communication to and fro

32、m a WD or to and from an SPT, the annunciation of the failure shall be processed (optional for grade 1 and grade 2). In the event of a failure of periodic communication, a fault or tamper shall be generated in accordance with EN 50131-1, clause relating to Signals and messages to be generated. NOTE

33、This requirement does not apply to portable devices (e.g. key fob). 4.6.3 Requirement for periodic communication before setting Setting shall be prevented in accordance with EN 50131-1, clause relating to Verification during setting procedure. These requirements do not apply to wire-free ACE (e.g. k

34、eyfob or portable remote control). 4.6.4 Requirement for the detection of interference If the level of modulated interference is great enough to corrupt the correct transmissions between equipments, detection of interference shall take place when such levels are detected for time periods as specifie

35、d in Table 5. Table 5 Detection of interference timings Detection of interference (maximum) Grades 1 and 2 Sum total of 30 s of interference signal in any 60 s Grades 3 and 4 Sum total of 10 s of interference signal in any 20 s For all grades, when modulated interference with: a level equal to IL (I

36、L is defined in 5.6.3) permanently applied, no indication or notification other than those specified in EN 50131-1, clause relating to signals or messages to be generated, shall take place; and a level as given in Table 7 and a duration less than 5 s, no indication or notification shall take place.

37、In the event of detection of modulated interference with a level as given in Table 7 and duration as given in Table 5, a fault or tamper shall be generated for grade 1 and grade 2 equipment and a tamper shall be generated for grade 3 and grade 4 equipment. The requirements given in Table 5 do not ap

38、ply to wire-free ACE (e.g. key fob or portable remote control). According to the grade of the system, the following requirements given in Table 6 for interference detection apply. BS EN 50131-5-3:2017 EN 50131-5-3:2017 11 Table 6 Detection of interference System state CIE/RE WD SPT Detection of inte

39、rference Grade 1 At all times Mandatory Optional aOptional Grade 2 At all times Mandatory Optional aOptional Grade 3 At all times Mandatory Mandatory Mandatory Grade 4 At all times Mandatory Mandatory Mandatory aFor external devices, if this function is provided, the WD shall conform to the requirem

40、ent for detection of interference The receiving equipment shall detect a level of interference as defined in Table 7, for the durations as defined in Table 9. Table 7 Level of interference signal Grade 1 IL + 40 dB Grade 2 IL + 30 dB Grade 3 IL + 9 dB Grade 4 IL + 9 dB The requirements given in Tabl

41、e 5, Table 6, and Table 7 apply to CIE, WD, RE and SPT. 4.7 Antenna 4.7.1 General The antenna shall have the same stability and tamper protection as required for the device. 4.7.2 Requirements for antenna For all grades equipment where antennas and/or an antenna cable is accessible at access level 1

42、 the requirements given in Table 8 shall be fulfilled. Table 8 Requirements for antenna Degrading of antenna performance CIE and RE Indicate fault and prohibit setting WD Local notification by device SPT Automatic transmission of tamper alarm For grade 3 and grade 4 equipment, antenna and/or an ante

43、nna cable shall fulfil the same tamper protection requirements as those of the device using this antenna. 5 Tests 5.1 General 5.1.1 For these tests, the manufacturer shall provide one system made of the receiving equipment to be tested (EUT Rx) with one or more transmitting equipment (EUT Tx) and re

44、mote control equipment. The equipment can be modified in order to trigger easily RF alarm messages and to advise easily the operator when an alarm message is processed. BS EN 50131-5-3:2017EN 50131-5-3:2017 12 5.1.2 Determination of reference level RL For most of the tests, the receiving equipment s

45、hall be set in a receiving state that just ensures a good reception. The level of this receiving state measured on the spectrum analyser according Annex A is called the reference level (RL). The reference level RL of the EUT Rx shall be determined and used as the basis for all other tests. This meas

46、urement shall be conducted using the arrangement shown in Annex A. The signal generator for the wanted signal is appropriately modulated to simulate a transmitted signal or an actual transmitting device may be used, via an attenuator to control the RF level. If using a real device, care shall be tak

47、en to ensure adequate isolation so that when the attenuator is set to maximum, the receiver will not receive the transmitting device through leakage between cables and connectors. The measurement of RL level shall be performed in the conditions (antenna polarization and EUT Rx orientation) where the

48、 EUT Rx receives the maximum signal. The interference signal source amplifier shall be turned ON when determining RL for immunity to interference tests (5.6) and can be turned OFF for other tests. To determine the reference level (RL) the wanted signal level is set at a point at which messages are r

49、eceived reliably and subsequently attenuated in appropriate steps until fewer than 80 % of alarm messages are received. Then decrease the attenuation in finer steps (e.g. 1 dB or 0,1 dB) until 80 % to 90 % of alarm messages are received. If this range is not achievable due to technical radio performance reasons then the nearest figure close to the range shall be used. In any case, this shall be not less than 80 %. When this point is reached, the wanted signal level is increased by 3 dB and this level
