ALARM SYSTEMS
Part 5: Requirements for alarm transmission systems
Section 1: General requirements for systems
1 Scope
This section of IEC 839-5 specifies the general requirements for the performance, re-
liability and security characteristics of alarm transmission systems.
It covers the general requirements for connections providing signalling between an alarm
system and an alarm receiving centre.
Additional requirements for specific alarm transmission systems are given in separate
sections as parts of IEC 839-5. This does not preclude the use of any transmission system
not - covered by one of these specific sections, provided that it meets these general
requirements.
This section does not specify the method of display of information and the installation of
equipment.
2 Normative references

4 General considerations
4.1 Applicable standards
Where use is made of public networks, the relevant recommendations (CCITT, CCIR, etc)
are applicable. Where appropriate, reference should also be made to the ISO Open
System Interconnection (OSI) layered architecture model.
4.2 System configuration
The logical configuration of an alarm transmission system is as shown in figure 1.
Depending upon the required reliability levels and the operational features of the alarm
receiving centres, various system configurations are possible, for instance:
- configuration with one alarm receiving centre (see figure 2);
- configuration with two alarm receiving centres of which the master is operating and
the slave is idle for back-up (see figure 3).
Other system configurations that meet the requirements of this section are acceptable.
Selection of the type of alarm transmission system used for an alarm system should be
dependent upon the required level of reliability and/or security. Reference should be made
to the separate standards describing the different types of alarm transmission systems.
In order to provide for increased communication reliability, more than one communication
channel may be used between an alarm system and one or more alarm receiving centres.
For the purpose of transmission redundancy, an alarm system may be connected to a
remote centre by more than one form of transmission, e.g. dedicated transmission paths
and digital communicators using the public switched network.
4.3 Transmission characteristics
The transmission of the state of the alarm system shall be:
a) continuous, or
b) periodic and/or
c)
by exception (whenever the state changes).
If transmission is not continuous, the control of transmission belongs to the following:
a) alarm system and/or
b)
alarm receiving centre, or
c) transmission system.
839-5-1 © IEC - 13 -
5 Requirements
The alarm transmission system shall provide communication between one or more alarm
systems and one or more alarm receiving centres.
5.1 Transmission facilities shared with other alarm systems
The alarm transmission system shall be such that adding, changing or removing sub-
scribers does not affect other subscribers' signals.
The communications between an alarm system and an alarm receiving centre shall
continue to meet the requirements of the appropriate class of table 1 in the presence of
any other normal signals carried by the same alarm transmission system.
For systems with automatic monitoring, abnormal signals and conditions which prevent the
correct operation of the alarm transmission system shall result in a fault signal.
The communications between an alarm system and an alarm receiving centre shall
continue to meet the requirements of the appropriate class of table 1 when alarm or fault
signals are generated at a rate equivalent to one such signal per minute from transmitters
representing up to 1 % of the system capacity.
If this rate of transmission is exceeded then the degree of degradation of performance of
the alarm transmission system shall be specified in the system specification. The
degradation shall be gradual (e.g. transmission times shall slowly increase) until a rate
equivalent to one such signal per minute from transmitters representing up to 10 % of the
system capacity is achieved and it shall return to meeting the requirements of this
standard within 5 min of the rate being reduced back to 1 %.
NOTE - Thus a system with 1 000 connected transmitters shall continue to meet the requirements of this
standard if alarms are being generated at a rate of 10/min.
5.2 Transmission facilities shared with non-alarm services
Transmission facilities shared with non-alarm services shall be so arranged that operation
and maintenance of the non-alarm services does not prevent the alarm transmission
system for meeting the requirements of this section.
NOTE - The above applies in the case of a switched network after the connection is established.
5.3 Performance
5.3.1 General
The alarm transmission system shall transmit information concerning the state of the
alarm system to the proper alarm receiving centre.

839-5-1 © !EC - 15 -
5.3.2 Transmission delay
The transmission delay shall not exceed the values specified in table 1 for the appropriate
class. The delay shall be measured from the time that the alarm system changes state
until the new state is reported to the alarm receiving centre, excluding any delay outside
the alarm transmission system. The delays within the alarm system and the alarm
receiving centre are specified in other related documents.

5.3.3 Monitoring of the interconnection with the alarm system
In the event of failure of the interconnection between the alarm system and the alarm
transmission system, an alarm or fault signal shall be transmitted to the alarm receiving
centre. The time to send the signal. shall meet the values specified cited in table 1 for the
appropriate class.
5.3.4
Monitoring of the alarm transmission system
For systems with automatic monitoring, the period from the time a fault develops in the
alarm transmission system until the fault information is reported to the alarm receiving
centre and/or monitoring centre shall not exceed the value specified in table 2 for the
appropriate class.

Alarm transmission system availability
5.3.5
The availability of the alarm transmission system is the percentage of time during which
the system is known to be available to transmit the status of an alarm from any enabled
alarm system connected to it to the predetermined alarm receiving centre(s) without
corruption and within the specified transmission delay and, where appropriate, to transmit
a message (e.g. an acknowledgement) from an alarm receiving centre to an alarm system.

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.

INTRODUCTION
The IEC 60811 series specifies the test methods to be used for testing non-metallic materials
of all types of cables. These test methods are intended to be referenced in standards for
cable construction and for cable materials.
NOTE 1 Non-metallic materials are typically used for insulating, sheathing, bedding, filling or taping within cables.
NOTE 2 These test methods are accepted as basic and fundamental and have been developed and used over
many years principally for the materials in all energy cables. They have also been widely accepted and used for
other cables, in particular optical fibre cables, communication and control cables and cables for ships and offshore
applications.
