FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60839-7-1 has been prepared by IEC technical committee 79: Alarm
systems.
This bilingual version (2001-11) replaces the English version.
The text of this standard is based on the following documents:
FDIS Report on voting
79/198/FDIS 79/208/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 3.
Annexes A and B are for information only.
The committee has decided that the contents of this publication will remain unchanged
until 2004. At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.

1 Scope
This part of IEC 60839 describes the requirements for standard serial data interfaces in alarm
transmission systems. It gives an outline of how alarm transmission systems are connected
and the various types of serial data interfaces that might be employed. This part includes a
range of examples.

3 Definitions
For the purpose of this part of IEC 60839, the following definitions apply.
3.1
alarm system messages
messages that convey information about the status of an alarm system
These may comprise:
3.1.1
alarm messages
messages that convey the presence of a hazard or a potential hazard to life or property, or the
removal of such a hazard, including messages that convey the status of an alarm since the
alarm transmission system is only responsible for decoding the type of the transmitted
message
3.1.2
commands
messages that give instructions to an alarm system or to part of the alarm transmission system
3.1.3
informative messages
messages that give information about the status of functions of an alarm system
3.1.4
transmission system messages
messages that convey the status of parts of the alarm transmission system, including
messages which report the status of the alarm system transceiver
NOTE The format and treatment of such messages may be the same as for alarm system messages.
3.2
alarm channel
part of the logical alarm transmission path across which information about the status of
separately identifiable logical functional parts of the connected alarm system are passed
3.3
functional part
logical function which may include individual detectors, groups of detectors and sections of the
common parts of the system (for example power supply unit (PSU), warning device, etc.)
NOTE Such a functional part may be in one or more of the following states as shown below.
3.3.1
normal condition
status of a functional part when it is fully operational and not in any other condition
3.3.2
alarm condition
status of a functional part which results from the response of that functional part to the
presence of an abnormal condition indicating the presence of a hazard (or a potential hazard)
which has not been acknowledged by either its successful transmission or by a local manual
action
60839-7-1 © IEC:2001 – 13 –
3.3.3
outstanding alarm
status of a functional part which results from the response of that functional part to the
presence of an abnormal condition indicating the presence of a hazard (or a potential hazard)
which has been acknowledged by either its successful transmission or by a local manual action
3.3.4
tamper
status of a functional part which results from the operation of a tamper device within that
functional part
3.3.5
test condition
status of the functional part which results from changing the status out of normal condition for
test purposes
3.3.6
disabled
status of the functional part in which the normal functions have been taken out of service
3.4
