EN 50136 consists of the following parts, under the general title Alarm systems Alarm transmissionsystems and e

21、quipment: Part 1: General requirements for alarm transmission systems; Part 2: Requirements for Supervised Premises Transceiver (SPT); Part 3: Requirements for Receiving Centre Transceiver (RCT); Part 4: Annunciation equipment used in alarm receiving centres (Technical Specification); Part 7: Applic

22、ation guidelines (Technical Specification); BS EN 50136-2:2013 EN 50136-2:2013 5 Part 9: Requirements for common protocol for alarm transmission using the Internet protocol(Technical Specification). BS EN 50136-2:2013 EN 50136-2:2013 6 1 Scope This European Standard specifies the general equipment r

23、equirements for the performance, reliability,resilience, security and safety characteristics of supervised premises transceiver (SPT) installed insupervised premises and used in alarm transmission systems (ATS). A supervised premisestransceiver can be a stand-alone device or an integrated part of an

24、 alarm system. These requirements also apply to SPTs sharing means of interconnection, control, communicationand power supplies with other applications. The alarm transmission system requirements and classifications are defined within EN 50136-1.Different types of alarm systems may in addition to al

25、arm messages also send other types ofmessages, e.g. fault messages and status messages. The term alarm is used in this broad sensethroughout the document. Additional requirements for the connection of specific types of alarmsystems are given in the relevant European Standards. Because the SPT can be

26、 applied in different applications (e.g. I Level 2: access to information about the operational status of the SPT. Access level 2 mayalso allow access to basic functional tests and the management of other Accesslevel 2 users; Level 3: maintenance and commissioning functions, access to affect the SPT

27、 configurationincluding the addition, removal or replacement of components and other operationsthat directly, or indirectly, may influence the functions of the SPT; Level 4: access to update the software and read-only functions. Access to level 2, 3 and level 4 functions shall require authorisation

28、with a key. Access at level 3 should be authorised by a user with level 2 access. Access at level 4 should beauthorised by a user with level 3 access. This may be achieved by a one time authorisation as part ofa service level agreement. Access at levels 2, 3 and 4 may be achieved providing authorisa

29、tion, equivalent to 1 000 000 keydiffers is achieved. Where it is possible to attempt to gain access more than 3 times in a 60-second period the SPT shallhave the ability to delay repeated attempts. After the third attempt, each further attempt shall beprevented for a minimum of 90 s. Where factory

30、default keys are provided, it shall not be possible to complete the SPT commissioningwithout first, changing these keys e.g. during installation. It shall not be possible to read any key thatprovides authorisation for access at levels 2, 3 or 4. BS EN 50136-2:2013 EN 50136-2:2013 9 5.3 Remote access

31、 Remote access to the SPT shall meet at least the same information security requirements that arerequired for alarm transmission as defined in EN 50136-1 for the appropriate category. 5.4 Uploading and downloading of software and firmware Where upload and download functions are provided, the upload

32、and download of software to a SPT isonly allowed to be performed by users with appropriate access level, as defined in 5.2. The software to be replaced by a software download shall be stored. If there is a loss of connection oranother transmission fault disrupts the download, the last fully function

33、al software version shall berestored, and the SPT shall work as before the unsuccessful download. EXAMPLE Procedure of a download: download software, check and validate the download, activate downloaded software. 5.5 Storage of parameters Power cycle or a boot up sequence shall not result in the los

34、s of any site specific data. The SPT shallreturn to normal operation. 5.6 ATS and ATP fault reporting to the AS Where the SPT is required to report an ATS and/or ATP failure to the AS as per EN 50136-1:2012,Table 5, this shall take place within the reporting times shown in EN 50136-1:2012, Table 3.

35、For an ATS with more than one ATP, as long as service is not lost, a single path line fault may be heldby the SPT for a period that is agreed between the interested parties until it is released to the AS. Where an AS includes the ability to display the status of each ATP the SPT may be configured to

36、 passindividual ATP failures to the AS within the reporting times shown in EN 50136-1:2012, Table 3. The manufacturers documentation should define the process for the reporting of ATS faults to the AS. 5.7 Interface to the AS The connections to the AS shall be monitored in accordance with EN 50136-1

37、. The maximum time to detect and generate an interface failure shall meet the requirements of theassociated application and shall not exceed the ATS reporting time of the appropriate category asspecified in EN 50136-1:2012, Table 3. To allow compatibility of equipment from different manufacturers, t

38、his European Standard specifiestwo electrical interfaces: parallel interface between AS and SPT, see A.1; serial interface between AS and SPT, see A.2. This does not exclude the use of any other type of interface to the AS, provided that the specificrequirements of this standard are met. The manufac

39、turer shall state in the associated documentation which type(s) of interface(s) to the ASare provided. BS EN 50136-2:2013 EN 50136-2:2013 10 5.8 Monitoring of the transmission network interface(s) Fault reporting If required by the ATS category, the SPT shall be configured to detect the failure of a

40、 transmissionnetwork interface and generate an ATP fault to the AS. The manufacturers documentation shall describe the process for monitoring and reporting the networkinterface fault to the AS. NOTE 1 The message generated by the SPT can indicate either an ATP fault or an interface fault. Where requ

41、ired, transmission network interface faults shall be reported within the time specified inEN 50136-1:2012, Table 3. For dual path category (Dx) ATSs, a fault on one of the transmission network interfaces shall bereported to the RCT over the remaining ATP within the time specified in EN 50136-1. NOTE

42、 2 An SPT network interface fault provides indication of a path fault. Monitoring the state of a transmission network interface should not be used to monitor the state of anassociated ATP. NOTE 3 An ATP can be in a failed state whilst the associated network interface is in an operational state. 5.9

43、Power supply for the SPT The SPT may be powered by the associated AS power supply (dedicated or shared) or by an integralSPT power supply. Where an integral SPT power supply is used, it shall meet the requirements of the most demandingassociated AS. 5.10 Event logging A logging function for all cate

44、gories of SPT except SP1 and DP1, shall be provided for the purposes ofproviding an audit trail and problem resolution. Dependent upon the ATS category where the SPT is applied, the events specified in Table 1 shall berecorded in the SPT. The means used to record the events shall be protected agains

45、t the accidental or deliberate deletionor alteration of the contents. The means of recording events shall be non-volatile and have a capacity complying with therequirements of Table 2. When the event recorder reaches maximum capacity, further events maycause the oldest events to be erased. The log s

46、hall record, in addition to the event, the time and date at which the event occurred. Thetiming resolution shall be a minimum of 1 s and it shall be accurate to the coordinated universal timewithin +/- 5 s. The SPT shall provide a means to adjust the date and time. Event optimisation is permitted, p

47、rovided that all diverse events are recorded and that the first and thelast repeated identical sequence of events in a 12 h period are recorded. Where this is done thenumber of repetitions need to be recorded. When required by Table 1, the logging of access to the SPT shall include user identificati

48、on. BS EN 50136-2:2013 EN 50136-2:2013 11 The inclusion of requirements to record events in Table 1 does not imply a requirement to provide theassociated function.
