1 Scope
This European Standard specifies the requirements for the performance, reliability and security
characteristics of alarm transmission systems.
It specifies the requirements for alarm transmission systems providing alarm transmission between an alarm
system at a supervised premises and annunciation equipment at an alarm receiving centre.
This European 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
European Standards.
2 Normative references

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 shall apply.
The intended users of this European 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 For example an SPT may 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.
5.2 ATS categories
5.2.1 General
An alarm transmission system shall be selected from one of ten categories described by this European
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 European 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 EN 50136-2 and EN 50136-3 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
