FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60839-5-1 has been prepared by IEC technical committee 79:
Alarm and electronic security systems.
This international standard is based on EN 50136-1:2012.
This second edition cancels and replaces the first edition published 1991. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) The previous version was published 24 years ago, techniques and constraints have been
widely changed since that time. Although covering the same subject the contents of the
new IEC 60839-5-1 are widely different and there is no constructive issues in trying to find
similarities and differences between both versions.
The text of this standard is based on the following documents:
FDIS Report on voting
79/479/FDIS 79/490/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
A list of all parts in the IEC 60839 series, published under the general title Alarm and
electronic security systems, can be found on the IEC website.
Future standards in this series will carry the new general title as cited above. Titles of existing
standards in this series will be updated at the time of the next edition.
The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,

5.1 ATS configuration
The logical configuration of an ATS shall be as shown in Figure 1. The main function of an
ATS is to provide a reliable and secure transmission network from the interface of the AS to
the SPT to the interface of the RCT to the AE for the transmission of alarms.
Depending upon the required reliability and resilience of the ATS and the operational features
of the ARC, various ATS configurations may be used, including the use of more than one ATP
between an AS and one or more RCTs connected to one or more AEs. Each ATP shall have
its own transmission network interface at the SPT.
NOTE 1 For example an SPT can use a fixed line network and a radio network.
Selection of the category of ATS used for an AS shall be determined by the required reliability
and security for the associated application. Reference should be made to the category of ATS
required and the options that may be selected.
NOTE 2 Examples of different ATS configurations are indicated in Annex A, Figures A.1 to A.3.
5.2 ATS categories
5.2.1 General
An alarm transmission system shall be selected from one of ten categories described by this

regulations for attachment to, establishment and termination of, connection and transmission
via public telephone and data networks and/or the regulations for transmission via the use of
radio, power distribution systems or cable TV distribution systems.
6 System requirements
6.1 General
The ATS shall provide communication between one or more ASs at one supervised premises
and one or more AEs of one or more ARCs.
6.2 Transmission link requirements
6.2.1 General
An ATP may include permanent dedicated links, permanent virtual links or switched links
which may use equipment that is not covered by the requirements of IEC 60839-5-2 and
IEC 60839-5-3 or may be affected by other applications sharing the transmission links.
An ATP may include:
– a transmission link that is shared with non-alarm data applications,
– a transmission link that carries other ATPs,
– equipment from a third party transmission network provider, which is not located at either
the supervised premises or the alarm receiving centre and is not classified as ATE,
– equipment from a third party which is located at the supervised premises but is not
classified as ATE.
The performance (reliability) of an ATS may be affected by:
– unwanted, malformed or otherwise malicious incoming data at the interfaces of the SPT or
RCT,
– transmission network congestion as a result of transmission link sharing,
– transmission network unavailability due to equipment failure and/or maintenance.
6.2.2 Transmission links shared with other applications
Transmission links shared with other applications shall be arranged such that operation and
maintenance does not prevent the ATS from meeting the requirements of this standard.
6.2.3 Transmission network equipment
Transmission equipment that is connected between the transmission network interface of the
SPT and the transmission network interface of the RCT and/or MCT is not subject to the
requirements of IEC 60839-5-2 and IEC 60839-5-3.
NOTE 1 Examples of SPT integrated network interfaces include analogue modems, DTMF transceivers, ISDN
terminal adapters, Ethernet modules, and GSM radio modules. No technologies are excluded.
NOTE 2 Equipment at the supervised premises will be subject to the application guidelines provided within
CLC/TS 50136-7.
NOTE 3 Local network interface failures can be detected and reported by the SPT to the RCT using the remaining
operational transmission path; however interface monitoring cannot be used to provide confirmation that a
transmission path is operational.
6.2.4 ATSN capacity
The ATSP shall provide a statement regarding the number of ASs that can be connected to
the ATSN that will ensure compliance with the requirements of Table 2.
Any single ATP shall continue to meet the requirements of the appropriate transmission time
and the maximum transmission time of Table 2:
a) at a rate equivalent to one such message per minute from each of a number of ASs
representing at least 0,1 % of the system capacity, and
b) at a rate of at least 2 alarms per minute at the RCT interface to the AE.
The evaluation shall be done when the ATSN is in a normal condition with the stipulated rate
of messages.
6.2.5 Denial of service
The ATS shall protect itself against Denial of Service (DoS) attacks from the transmission
network.
Any form of incoming data or signal received from a transmission network shall not prevent
the ATP from performing as specified, unless the amount of incoming data leads to
congestion of the transmission link. ATP performance deterioration is not allowed when there
is enough remaining network capacity to carry ATP signalling.
Any malicious data received by a transmission network interface, shall not affect the operation
of the ATE (SPT, RCT or MCT) or the operation of any other transmission network interface.
– 16 – IEC 60839-5-1:2014 © IEC 2014
This applies even if the malicious data rate reaches the capacity of a single interface,
rendering the interface itself inoperable.
If the performance of the ATS is affected by a DoS attack, a fault signal shall be generated
according to the monitoring and fault reporting requirements of the applicable category.
NOTE 1 This requirement is intended to emphasize the need to protect against attacks where malicious data or
signalling is used to interfere with the operation of the ATE. These attacks can be performed either by malicious
signalling designed to impair the ATE or by overloading the communications with large amounts of data.
NOTE 2 DoS attacks can be present in any network, e.g. IP networks, PSTN networks. Examples of such attacks
are: devices deliberately overloading the IP network, automatic dialling facilities to overload parts of PSTN
networks, jamming devices to interfere with radio communications, etc.
6.3 Performance
6.3.1 General
For the categorisation of the ATS the following parameters are used:
– transmission time; average, 95 % and maximum;
– reporting time;
– monitoring of interconnections;
– ATSN availability.
6.3.2 Transmission time
The arithmetic mean of the alarm transmission time and 95 % of the measurements of the
transmission time shall not exceed the values specified in Table 2 for the appropriate
category.
Any transmission time exceeding the maximum acceptable transmission time of Table 2 for a
specific system shall, for each incident, be classified as a transmission system fault in
accordance with NOTE 7.
The time is measured from the time when a change of state occurs or an alarm message is
presented for transmission at the SPT interface to the AS until the time that the new state or
message is reported at the RCT interface to the AE.
The transmission time applies to all changes of state or message that are transmitted from the
AS through the SPT interface to the ATS.
NOTE 1 Where the SPT interface to the AS is not accessible the measurement can be made from a more
accessible point before the SPT interface to the AS and an appropriate correction applied to the result.
NOTE 2 Where the RCT interface to the AE is not accessible, or where it is more convenient, the measurement
can be made to a point after the RCT interface to the AE and an appropriate correction applied to the result.
NOTE 3 Times within the AS and within the AE will be specified in other standards.
NOTE 4 For most ATS(s) there exists a direct relation between the classification of Tables 2 and 3.
NOTE 5 The transmission time includes the time to establish a connection.

Where the transmission time cannot be measured directly then it is acceptable that the round-
trip time may be measured. In this case the round-trip time shall meet the same requirements
as the transmission time for the appropriate category in Tables 2 and 3.

General requirements
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60839-5-1 has been prepared by IEC technical committee 79:
Alarm and electronic security systems.
This international standard is based on EN 50136-1:2012.
This second edition cancels and replaces the first edition published 1991. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) The previous version was published 24 years ago, techniques and constraints have been
widely changed since that time. Although covering the same subject the contents of the
new IEC 60839-5-1 are widely different and there is no constructive issues in trying to find
similarities and differences between both versions.
The text of this standard is based on the following documents:
FDIS Report on voting
79/479/FDIS 79/490/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
A list of all parts in the IEC 60839 series, published under the general title Alarm and
electronic security systems, can be found on the IEC website.
Future standards in this series will carry the new general title as cited above. Titles of existing
standards in this series will be updated at the time of the next edition.
The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

INTRODUCTION
The object of this part of IEC 60839 is to specify the general requirements for the
performance, reliability, resilience and security of alarm transmission systems and to ensure
their suitability for use with different types of alarm systems and annunciation equipment.
An alarm transmission system may use any type of transmission network.
When the ATS functions are integrated into an alarm system or annunciation equipment the
requirements of this standard apply.
The intended users of this standard include alarm transmission service providers, alarm
receiving centre operators, fire departments, insurance companies, telecommunication
network operators, internet service providers, equipment manufacturers, alarm companies,
end users and others.
The IEC 60839-5 series consists of the following parts, under the general title Alarm and
electronic security systems:
– Part 5-1: Alarm transmission systems – General requirements;
– Part 5-2: Alarm transmission systems – Requirements for supervised premises transceiver
(SPT);
– Part 5-3: Alarm transmission systems – Requirements for receiving centre transceiver
(RCT);
– Part 5-4 : (under evaluation);
– Part 5-5 : (under evaluation);
– Part 5-6 : (under evaluation);

_______________
1 The former IEC 60839-5 series (1991) is being reviewed by an ad-hoc group set-up at the TC 79 meeting in
Milano in October 2013. This ad-hoc group is in charge of evaluating the relevance / obsolescence of all parts
of IEC 60839-5 series. The result of this analysis can be found in 79/462/DC and 79/477/INF that recommend to:
– keep IEC 60839-5-1 and IEC 60839-5-2 to receive, under identical titles, updated contents, such as the
present document;
– withdraw IEC 60839-5-4, IEC 60839-5-5 and IEC 60839-5-6 developed in 1991 that have now no relevance.
ALARM AND ELECTRONIC SECURITY SYSTEMS –
Part 5-1: Alarm transmission systems –
General requirements
1 Scope
This part of IEC 60839 specifies the requirements for the performance, reliability, resilience
and security of alarm transmission systems and ensures their suitability for use with different
types of alarm systems and annunciation equipment.
An alarm transmission system may use any type of transmission network. When the ATS
functions are integrated into an alarm system or annunciation equipment the requirements of
this standard apply.
This standard specifies the requirements for alarm transmission systems providing alarm
transmission between an alarm system at supervised premises and annunciation equipment at
an alarm receiving centre.
This standard applies to transmission systems for all types of alarm messages such as fire,
intrusion, access control, social alarm, etc. Different types of alarm systems may in addition to
alarm messages also send other types of messages, e.g. fault messages and status
messages. These messages are also considered to be alarm messages in the context of this
standard. The term alarm is used in this broad sense throughout the document.
Additional alarm transmission requirements of specific types of alarm systems are given in the
relevant standards. The intended users of this standard include alarm transmission service
providers, alarm receiving centre operators, fire departments, insurance companies,
telecommunication network operators, internet service providers, equipment manufacturers,
alarm companies, end users and others.

5 General requirements
5.1 ATS configuration
The logical configuration of an ATS shall be as shown in Figure 1. The main function of an
ATS is to provide a reliable and secure transmission network from the interface of the AS to
the SPT to the interface of the RCT to the AE for the transmission of alarms.
Depending upon the required reliability and resilience of the ATS and the operational features
of the ARC, various ATS configurations may be used, including the use of more than one ATP
between an AS and one or more RCTs connected to one or more AEs. Each ATP shall have
its own transmission network interface at the SPT.
NOTE 1 For example an SPT can use a fixed line network and a radio network.
Selection of the category of ATS used for an AS shall be determined by the required reliability
and security for the associated application. Reference should be made to the category of ATS
required and the options that may be selected.
NOTE 2 Examples of different ATS configurations are indicated in Annex A, Figures A.1 to A.3.
5.2 ATS categories
5.2.1 General
An alarm transmission system shall be selected from one of ten categories described by this
standard. An ATS shall be allocated a category which will determine its performance and
resilience.
Categories SP1 to SP6 are based on single ATP ATSs.
Categories DP1 to DP4 add resilience by requiring alternate ATPs.

5.2.2 Custom category
5.2.2.1 General
Where an application cannot be satisfied by any of the categories of this standard a new
custom category, category C, shall be defined within an application specific standard using
parameters from the classes defined in Annex D.
Where a custom category is used reference shall be made to the tables in Annex D instead of
the category tables, Table 1 to Table 9. All other requirements of this standard shall apply.
5.2.2.2 Documentation
Where there is a requirement for a custom category C, it shall include the rationale for the
choice of a custom category and there shall be sufficient documentation for the verification of
performance.
A statement shall be made referring to the requirements listed in Tables 1, 4, 5 and 6.
5.3 Applicable network standards
Equipment and systems shall meet local, national and international requirements and
regulations for attachment to, establishment and termination of, connection and transmission
via public telephone and data networks and/or the regulations for transmission via the use of
radio, power distribution systems or cable TV distribution systems.
6 System requirements
6.1 General
The ATS shall provide communication between one or more ASs at one supervised premises
and one or more AEs of one or more ARCs.
6.2 Transmission link requirements
6.2.1 General
An ATP may include permanent dedicated links, permanent virtual links or switched links
which may use equipment that is not covered by the requirements of IEC 60839-5-2 and
IEC 60839-5-3 or may be affected by other applications sharing the transmission links.
An ATP may include:
– a transmission link that is shared with non-alarm data applications,
– a transmission link that carries other ATPs,
– equipment from a third party transmission network provider, which is not located at either
the supervised premises or the alarm receiving centre and is not classified as ATE,
– equipment from a third party which is located at the supervised premises but is not
classified as ATE.
The performance (reliability) of an ATS may be affected by:
– unwanted, malformed or otherwise malicious incoming data at the interfaces of the SPT or
RCT,
– transmission network congestion as a result of transmission link sharing,
– transmission network unavailability due to equipment failure and/or maintenance.
6.2.2 Transmission links shared with other applications
Transmission links shared with other applications shall be arranged such that operation and
maintenance does not prevent the ATS from meeting the requirements of this standard.
6.2.3 Transmission network equipment
Transmission equipment that is connected between the transmission network interface of the
SPT and the transmission network interface of the RCT and/or MCT is not subject to the
requirements of IEC 60839-5-2 and IEC 60839-5-3.
NOTE 1 Examples of SPT integrated network interfaces include analogue modems, DTMF transceivers, ISDN
terminal adapters, Ethernet modules, and GSM radio modules. No technologies are excluded.
NOTE 2 Equipment at the supervised premises will be subject to the application guidelines provided within
CLC/TS 50136-7.
NOTE 3 Local network interface failures can be detected and reported by the SPT to the RCT using the remaining
operational transmission path; however interface monitoring cannot be used to provide confirmation that a
transmission path is operational.
6.2.4 ATSN capacity
The ATSP shall provide a statement regarding the number of ASs that can be connected to
the ATSN that will ensure compliance with the
