100 1 Scope
101 This European Standard specifies the general equipment requirements for the performance, reliability,
102 resilience, security and safety characteristics of supervised premises transceiver (SPT) installed in
103 supervised premises and used in alarm transmission systems (ATS). A supervised premises
104 transceiver can be a stand-alone device or an integrated part of an alarm system.
105 These requirements also apply to SPT’s sharing means of interconnection, control, communication
106 and power supplies with other applications.
107 The alarm transmission system requirements and classifications are defined within EN 50136-1.
108 Different types of alarm systems may in addition to alarm messages also send other types of
109 messages, e.g. fault messages and status messages. The term alarm is used in this broad sense
110 throughout the document. Additional requirements for the connection of specific types of alarm
111 systems are given in the relevant European Standards.
112 Because the SPT can be applied in different applications (e.g. I&HAS, fire and social alarm systems),
113 requirements for the SPT, additional to those of this European Standard, may be specified in separate
114 application specific documents.
115 This European Standard specifies the requirements specific to alarm transmission. Application specific
116 requirements for the connection of the SPT to specific types of alarm systems are given in the
117 EN/TS 50131 series for I&HAS, and EN 54 series for fire. For other SPT applications, see the relevant
118 National or European standards

163 4.2 SPT classification
164 This European Standard defines SPT requirements. For some specific characteristics also, a
165 classification system or measuring scale is introduced. For the purpose of SPT classification,
166 reference is made to the ATS categories in EN 50136-1. The SPT shall be labelled with each category
167 or range of categories that it can be applied to.
168 If a Custom Category (category C) is defined then the requirements corresponding to Tables 1, 2
169 and 3 shall also be defined.
170 5 Functional requirements
171 5.1 General
172 The SPT shall be able to receive alarms from one or more ASs and transmit the alarm to one or more
173 RCTs via one or more ATPs within the requirements of the appropriate ATS category.
174 5.2 Access levels
175 This European Standard specifies three levels of access that categorise the ability of users to access
176 the SPT functions.
177 Access levels are defined as following:
178 Level 1 access to functions, indications and notifications available to any individual without
179 authentication;
180 Level 2 access to information about the operational status of the SPT. Access level 2 may also allow
181 access to basic functional tests and the management of other Access level 2 users;
182 Level 3 maintenance and commissioning functions, access to affect the SPT configuration including
183 software changes, the addition, removal or replacement of components and other operations
184 that directly, or indirectly, may adversely influence the functions of the SPT.
185 Access to level 2 and level 3 functions shall require authorisation with a key.
186 NOTE Access at level 3 should be authorised by a user with level 2 access. This may be achieved by a one time authorisation
187 as part of a service level agreement.
188 Access at levels 2 & 3 may be achieved remotely providing authorisation, equivalent to 1 000 000 key
189 differs is achieved.
190 Where it is possible to gain local access more frequently than 3 times in any 60 s period, then the
191 number of successive failed attempts shall be limited to three, continued attempts shall not be
192 permissible for a further 300 s as a minimum.
193 Where factory default keys are provided, it shall not be possible to complete the SPT commissioning
194 without first, changing these keys e.g. during installation. It shall not be possible to read any key that
195 provides authorisation for access at levels 2 or 3.
196 5.3 Remote access
197 Remote access to the SPT shall meet at least the same information security requirements that are
198 required for alarm transmission as defined in EN 50136-1 for the appropriate category.

199 5.4 Uploading and downloading of software and firmware
200 Where upload and download functions are provided, the upload and download of software to a SPT is
201 only allowed to be performed by users with appropriate access level, as defined in 5.2.
202 The software to be replaced by a software download shall be stored. If there is a loss of connection or
203 another transmission fault disrupts the download, the last fully functional software version shall be
204 restored, and the SPT shall work as before the unsuccessful download.
205 EXAMPLE Procedure of a download: download software, check and validate the download, activate downloaded software.
206 5.5 Storage of parameters
207 Power cycle or a boot up sequence shall not result in the loss of any site specific data. The SPT shall
208 return to normal operation.
209 5.6 ATS and ATP fault reporting to the AS
210 Where the SPT is required to report an ATS and/or ATP failure to the AS as per EN 50136-1:201X,
211 Table 5, this shall take place within the reporting times shown in EN 50136-1:201X, Table 3.
212 NOTE 1 For an ATS with more than one ATP, as long as service is not lost, a single path line fault may be held by the SPT for
213 a period that is agreed between the interested parties until it is released to the AS.
214 NOTE 2 Where an AS includes the ability to display the status of each ATP the SPT may be configured to pass individual ATP
215 failures to the AS within the reporting times shown in EN 50136-1:201X, Table 3.
216 The manufacturer’s documentation should define the process for the reporting of ATS faults to the AS.
217 5.7 Interface to the AS
218 The connections to the AS shall be monitored in accordance with EN 50136-1.
219 To allow compatibility of equipment from different manufacturers, this European Standard specifies
220 two electrical interfaces:
221 • parallel interface between AS and SPT, see Clause A.1;
222 • serial interface between AS and SPT, see Clause A.2.
223 The manufacturer shall state in the associated documentation which type(s) of interface(s) to the AS
224 are provided.
225 5.8 Monitoring of the transmission network interface(s) – Fault reporting
226 If required, the SPT shall be configured to detect the failure of a transmission network interface and
227 generate an ATP fault to the AS.
228 The manufacturer's documentation shall describe the process for monitoring and reporting the network
229 interface fault to the CIE.
230 NOTE 1 The message generated by the SPT may indicate either an ATP fault or an interface fault.
231 Where required, transmission network interface faults shall be reported within the time specified in
232 EN 50136-1:201X, Table 3.

---------------------- Page: 10 ----------------------
oSIST prEN 50136-2:2011
– 9 – prEN 50136-2:2011
233 For dual path category (Dx) ATSs, a fault on one of the transmission network interfaces shall be
234 reported to the RCT over the remaining ATP within the time specified in EN 50136-1.
235 NOTE 2 An SPT network interface fault provides indication of a path fault.
236 NOTE 3 Monitoring the state of a transmission network interface should not be used to monitor the state of an associated ATP.
237 NOTE 4 An ATP may be in a failed state whilst the associated network interface is in an optional state.
238 5.9 Power supply for the SPT
239 The SPT may be powered by the associated AS power supply or by a dedicated SPT power supply.
240 Where a dedicated SPT power supply is used, it shall meet the requirements of the most demanding
241 associated alarm system.
242 5.10 Event logging
243 A logging function for all categories of SPT except S1 and D1, shall be provided for the purposes of
244 providing an audit trail and problem resolution.
245 Dependent upon the ATS category where the SPT is applied, the events specified in Table 1 shall be
246 recorded in the SPT.
247 The means used to record the events shall be protected against the accidental or deliberate deletion
248 or alteration of the contents.
249 The means of recording events shall be non-volatile and have a capacity complying with the
250 requirements of Table 2. When the event recorder reaches maximum capacity, further events may
251 cause the oldest events to be erased.
252 The log shall record, in addition to the event, the time and date at which the event occurred.
253 The timing resolution shall be a minimum of 1 s and it shall be accurate to within ± 1 s per 24 h.
254 The SPT shall provide a means to adjust the date and time.
255 To optimise storage of events, where identical sequentially repeated events occur within any 12 h
256 period, then only the first and last event may be recorded. Where this is done then the number of
257 identical events shall be recorded.
258 When required by Table 1, the logging of access to the SPT shall include user identification.
259 The inclusion of requirements to record events in Table 1 does not imply a requirement to provide the
260 associated function.

265 6 Operation
266 6.1 Modes of acknowledgement operation
267 6.1.1 General
268 Two modes of operation are permitted:
269 a) store-and-forward;
270 b) pass-through.
271 The manufacturer shall declare in the product documentation which of the two mode(s) are supported.
272 6.1.2 Store-and-forward operation requirements
273 When an alarm is received from the AS, the SPT shall secure the alarm and provide acknowledgment
274 of the correct receipt of the alarm to the AS.
275 If the store-and-forward operation is used, all alarm messages shall include a date and time stamp
276 that is accurate to the resolution specified in 5.10.
277 Securing the alarm shall be achieved by storing the alarm in the SPT’s non-volatile memory, this is to
278 secure alarms during a power failure or other ATS failure; stored alarms shall be transmitted when the
279 fault condition clears.
280 The secured alarm shall be transmitted from the SPT to the RCT.
281 The reception of an acknowledgement from the RCT shall not be forwarded to the AS, since the AS
282 has already received an acknowledgement from the SPT.
283 NOTE The loss of an alarm message is regarded as a worse situation than sending a delayed message.
