FOREWORD
1)
The formal decisions or agreements of the IEC on technical matters,
prepared by Technical Committees on which all the National Committees
having a special interest therein are represented, express, as nearly
as possible, an international consensus of opinion on the subjects
dealt with.
2)
They have the form of recommendations for international use and they
are accepted by the National Committees in that sense.
3) In order to promote international unification, the IEC expresses the
wish that all National Committees should adopt the text of the IEC
recommendation for their national rules in so far as national
conditions will permit. Any divergence between the IEC recommendation
and the corresponding national rules should, as far as possible, be
clearly indicated in the latter.
PREFACE
This standard has been prepared by IEC Technical Committee No. 79:
Alarm systems.
The text of this standard is based upon the following documents:
Six Months' Rule

ALARM SYSTEMS
Part 2: Requirements for intruder alarm systems
Section 4 - Ultrasonic Doppler detectors
for use in buildings
1. Scope
This International Standard gives the specific requirements and test
procedures for ultrasonic Doppler detectors for use in intruder alarm
systems installed in buildings.
This standard is an addition to the general requirements for
detectors for use in intruder alarm systems as specified in IEC Publi-
cation 839-2-2, and it shall also be used in conjunction with the
standard for general requirements for alarm systems, IEC Publi-
cation 839-1-1.
The object of this standard is to specify those requirements for
ultrasonic Doppler detectors which will ensure that they will perform
satisfactorily and minimize false alarms.
2. Normative references
The following standards contain provisions which, through reference
in this text, constitute provisions of this International Standard. At
the time publication, the editions indicated were valid. All standards
are subject to revision, and parties to agreements based on this
International Standard are encouraged to investigate the possibility of
applying the most recent editions of the standards indicated below.
Members of IEC and ISO maintain registers of currently valid Inter-
national Standards.

3. Definitions
For the purpose of this standard the following definitions apply in
addition to those given in the general requirements
3.1 Ultrasonic Doppler detector
A detector which generates an alarm condition in response to the
frequency shift of the reflection of ultrasonic radiation from a moving
person.
3.2 Sensor
The transmitting and receiving elements of the detector.
3.3
Ultrasonic radiation
A sonic radiation with a frequency above 22 kHz.
3.4 Reference target
A person weighing between 50 kg and 70 kg and between 165 cm and
180 cm in height, wearing a cotton overall.
3.5 Boundary of detection coverage
The furthest radial distances in all directions at which a reference
target moving towards the detector will generate an alarm condition.
3.6
Detection ranges
The detection ranges for given directions are the radial distances
from the detector to the boundary of detection coverage.
4.
General considerations
The detector shall consist of one or more sensors and a processor.
Each sensor shall be contained in one housing which may also include
the processor. Where facilities are included to permit more than one
sensor to be connected to the processor, the tests required under
Clause 6 shall be carried out with one sensor only.
The detectors may have means incorporated to vary the shape of the
boundary of coverage. Where such means are incorporated the tests
required under Clause 6 shall be carried out with the normal
equipment and setting but additional tests shall be carried out to
prove the manufacturer's claims for the effects of these means.

839-2-4 © IEC
5. Requirements
5.1 Functional
5.1.1
Frequency
The operating frequency of the detector shall be not less than
22 kHz. Any radiation below 20 kHz shall be not more than 40 dBA
at 0,5 m from the detector.
5.1.2
Boundary of detection coverage
The boundary of detection coverage achieved for any detector at
maximum range setting shall be at least equal to but not more than 25%
greater than that given in the manufacturer's specifications.
5.1.3
Signal processing
The detector shall generate an alarm condition as a result of the
reference target moving towa

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.
