European foreword
This document (EN 50136-2:2013/A1:2023) has been prepared by CLC/TC 79 “Alarm systems”.
The following dates are fixed:
• latest date by which this document has to be (dop) 2024-02-13
implemented at national level by publication of
an identical national standard or by
endorsement
• latest date by which the national standards (dow) 2026-02-13
conflicting with this document have to be
withdrawn
Amendment 1 to EN 50136-2:2013 makes miscellaneous changes to correct errors and to better reflect the
current state of the art.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CENELEC shall not be held responsible for identifying any or all such patent rights.
Any feedback and questions on this document should be directed to the users’ national committee. A complete
listing of these bodies can be found on the CENELEC website.
1 Modification to subclause 4.2, “SPT classification”
Delete the existing second paragraph and replace with the following text:
“When the SPT is used together with or integrated in associated alarm systems, in case of requirement conflict,
the most demanding requirement shall apply.”
2 Modification to subclause 5.6, “ATS and ATP fault reporting to the AS”
Rename the subclause as follows:
“5.6  ATS fault reporting to the AS”
Delete the paragraph and replace with the following text:
“Where the SPT is required to report an ATS failure to the AS as per EN 50136-1:2012, Table 5, this shall
take place within the reporting times of ‘failure of all ATPs at the same time’ shown in EN 50136-1:2012 ,
Table 3 (last row).
The manufacturer’s documentation should define the process for the reporting of ATS faults to the AS.”
3 Modification to subclause 5.7, “Interface to the AS”
Replace paragraph 3 with the following text:
“To allow compatibility of equipment from different manufacturers, this document provides two possible
standard interfaces”:
4 Modification to subclause 5.8, “Monitoring of the transmission network
interface(s) – Fault reporting”
Delete the existing text and replace with the following:
“If network interface monitoring and fault reporting to the AS and/or RCT is implemented, the manufacturer's
documentation shall describe how this is achieved.
NOTE Implementation of network interface monitoring and fault reporting is not mandatory. However, it can be useful
for the ATSP to help determine and analyse the cause of ATP failures.”
5 Modification to subclause 5.10, “Event logging”
Delete the existing fourth paragraph and replace with the following text:
“The means of recording events shall be non-volatile and have a capacity complying with the requirements of
Table 2. When the event recorder reaches maximum capacity, further events may cause the oldest events to
be erased. When the event log memory is shared with another application, the minimum requirements of
Table 2 shall be met for the SPT events and shall not be overwritten by any other application.”
Delete existing text between Table 1 and Table 2 and replace with the following text:
“Where the SPT and the AS are integrated into a single device they may share the same internal memory
provided that the minimum logging requirements for both SPT and AS are met.”

As amended by EN 50136-1:2012/A1:2018.
6 Modification to subclause 6.1, “Modes of acknowledgement operation”
Rename the subclause as follows:
“6.1  Mode of operation”
Delete the existing clause and replace by the following text:
“When an alarm is received by the SPT, the SPT shall secure the alarm and acknowledge the correct receipt
of the alarm to the AS.
The SPT shall deliver the alarm to the RCT according to the requirements of the ATS category selected.
All alarm messages shall include a date and time stamp that is accurate to the resolution specified in 5.10.
Securing the alarm shall be achieved by storing the alarm in the SPT’s non-volatile memory, this is to secure
alarms during a power failure or other ATS failure; stored alarms shall be transmitted when the fault condition
clears.
NOTE 1 The loss of an alarm message is regarded as a situation that is worse than sending a delayed message.
NOTE 2 If an ATS fault is detected after the SPT received and secured the alarm, this will be reported to both the AS
and the AMS in accordance with the requirements of EN 50136-1.”
Delete subclauses 6.1.1, 6.1.2 and 6.1.3.
Add the following subclause 6.5:
“6.5  Means of ATS performance verification
Where applicable for the ATS categories supported by the SPT, and where the SPT has integrated functions
to monitor the performance of the ATS, the manufacturer shall provide in his/her documentation a description
of how this is achieved.
The manufacturer documentation shall describe the means to achieve the following performance
measurements:
— transmission time (EN 50136-1:2012 , Table 2),
— reporting time (EN 50136-1:2012 , Table 3),
— ATS Availability (EN 50136-1:2012 , Table 6).”
7 Modification to subclause 7.1, “SPT documentation”
Add the following item to the list of SPT documentation items:
“
— Description of test to verify the ATS performance to achieve compliance with EN 50136-1:2012 , Table 2,
Table 3 and Table 6.”
8 Modification to subclause 9.1, “General”
Delete the existing paragraph and replace with the following text:
“9.1  General
The manufacturer shall provide a fully functional test setup. Other ATS components such as AS, network and
the RCT may be provided as simulating equipment and/or network(s).
Where an RCT (or simulated RCT) is required for the tests, it shall be capable of meeting the requirements of
EN 50136-1.
The tests shall be reproducible and deliver the same results when carrying out the same test procedure.”
9 Modification to subclause 9.4.1, “General”
Replace Table 4 with the following:
“
