Introduction
To come to a common understanding of the alarm transmission standards documents there is a need
for application guidelines to support other TC 79 WG, other standardisation bodies, insurance
companies and customers to require an appropriate performance of the alarm transmission system for
a specific application.
Application knowledge and needs are not always available by the alarm transmission experts and
therefore guidelines for alarm transmission should assist other experts to understand the alarm
transmission standards and the performance of an alarm transmission system. This should help to
make an appropriate specification based on the performance tables of the general standard, also
including the economical aspects and consequences.
The alarm transmission standards applies to different applications (e.g. intrusion, fire, access control,
CCTV,.). Therefore, this guideline should be read in conjunction with the standards relating to these
applications when appropriate.
Several alarm transmission systems may be used by the providers of alarm transmission services,
which implies that the level of services may vary, depending on the performance of each alarm
transmission system.
1 Scope
This Technical Specification will give to the readers of the alarm transmission system standards
appropriate guidance to define alarm transmission and annunciation equipment systems in line with the
requirements of their specific applications.
2 Normative references
This Technical Specification incorporates by dated or undated reference, provisions from other
publications. These normative references are cited at the appropriate places in the text and the
publications are listed hereafter. For dated references, subsequent amendments to or revisions of any
of these publications apply to this application guideline only when incorporated in it by amendment or
revision. For undated references the latest edition of the publication referred to apply (including
amendments).

3 Definitions
For the purposes of this Technical Specification, the definitions in EN 50136-1-1 apply.
4 Alarm transmission systems
4.1 General and technology specific requirement
Alarm transmission systems are a part of a total security solution. The selection of requirements for the
alarm transmission system depends on the requirements of the specific application.
The alarm transmission standards parts EN 50136-1-1 and EN 50136-2-1 are the main documents.
They provide requirements for all types of systems and equipment commonly in use.
For some specific technologies there are standards providing detailed additional requirements or
interpretations or explanations for the application of the general requirements.
For technologies not covered by a specific standard document, the general documents EN 50136-1-1
and EN 50136-2-1 should apply.
4.2 Purpose of an alarm transmission system
The purpose of an alarm is always to initiate some kind of response, locally or remotely. The function
of the alarm is in some cases twofold, to prevent something from occurring, e.g. burglary, and to
respond when something occurs. The most common set-up is with an alarm equipment including
detection of the expected incidents, an alarm transmission system, a monitoring centre and a response
force, police, guards, fire brigade, medical assistance, etc.
The characteristics of each of these parts of the total preventive and responsive system should
correspond to the nature of the threat, for which it provides protection:
• for a burglar alarm, tamper and manipulation protection are important characteristics: the higher the
values or risks, the more important is also the availability of the system;
• for a fire alarm system the most important characteristics may be transmission time and availability,
of course related to the values at risk).
Sufficient information should be provided through the alarm transmission system to enable appropriate
intervention.
Examples of useful information are
• fault,
• set/unset (arm/disarm),
• alarm including type, location and also detector or zone,
• power failure/battery fault.

4.3 Components of an alarm transmission system (Annex A)
The alarm transmission system has several parts. The supervised premises transceiver is the part
which is located at the premises and which receives the alarm status signal(s) from the local alarm
system. It transmits the corresponding alarm through a transmission network (which is, in most
cases, a network provided by a telephone network operator), to a receiving centre transceiver
located in a remote centre or in an alarm receiving centre.
The message corresponding to the alarm is then passed to the annunciation equipment, which
secures its presentation. The annunciation equipment can be either located in the same alarm
receiving centre as the receiving centre transceiver or in a different one.
4.4 Performance of an alarm transmission system
The performance of the alarm transmission system is evaluated from the criterias of transmission time
of alarm messages, the reporting time of faults, the signalling security and the availability including the
transmission network.
The transmission network should be selected according to the required performance. As the
transmission network performance can not be influenced, prior to selecting the alarm transmission
system performance, the inherent performance of the transmission network should be assessed with
the network operator.
For alarm transmission systems which are not automatically monitored, the verification of performance
should be carried out manually, following a documented procedure. This procedure should use a
check-list which should take into account every component of the alarm transmission system which
may influence its performance.
4.4.1 Transmission time
The transmission time (see Table 1 of Annex B) is the time it takes to convey the alarm message, from
when the alarm is signalled to the supervised premises transceiver to the receiving centre transceiver.
As the transmission time may vary from one transmission to another, due to the transmission network
(availability of lines, type and number of exchanges,.), this value is considered statistically. This is the
reason to specify the arithmetic mean and the upper 95 % of this value.
When designing a system to a certain target in this table it is important to verify that the inherent
performance of the network, allows to meet the selected class from Table 1 (see Annex B). In addition,
the worse case value of transmission time shall be considered in order to verify that this value is under
the limits of the application. The highest classes providing a short transmission time are more relevant
if the corresponding response time is immediate or short.
The maximum time (see Table 2 in Annex B) is an absolute limit to be specified separately. Each
occasion when the maximum time is exceeded should be considered as a fault during the verification
of performance. Each fault affects the availability criteria of the alarm transmission system.
4.4.2 Reporting time
The reporting time (given by Table 3 in Annex B) is the period from the time a fault occurs in the alarm
transmission system until a fault message is reported to the receiving centre transceiver. It is used to
prove that the alarm transmission system is operational as it basically gives the physical availability of
the alarm transmission system. The fault reporting time relates to transmission time requirements,
availibility and manipulation protection.
There may be different ways to evaluate the reporting time in order to establish a classification. The
selected method should be assed in a clear written procedure.

Some examples of this evaluation are
• measuring from the time the last successful message was received by the alarm receiving centre
(at the receiving centre transceiver or at the annunciation equipment),
• monitoring continually by using test messages.
