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.

Part 3 Control and indicating equipment
Part 4 Warning devices
Part 5-3 Requirements for interconnections equipment using radio frequency
techniques
Part 6 Power supplies
Part 7 Application guidelines
Part 8 Security fog devices/systems
This standard deals with microwave detectors (to be referred to as the detector) used as part
of intrusion alarm systems installed in buildings. It includes four security grades and four
environmental classes.The purpose of a detector is to emit microwave radiation and analyse returned signals to
detect an intruder and to provide the necessary range of signals or messages to be used by
the rest of the intrusion alarm system.The number and scope of these signals or messages will be more comprehensive for systems
that are specified at the higher grades.This specification is only concerned with the requirements and tests for the detector. Other
types of detector are covered by other documents identified as IEC 62642-2 series.

NOTE 1 This permits two methods of signalling a masking or reduction of range event: either by the intrusion
signal and fault signal, or by a dedicated masking or reduction of range signal or message. Use of the intrusion
signal and fault signal is preferable, as this requires fewer connections between CIE and detector. If multiple
events overlap there will be some signal combinations that may be ambiguous. To overcome this ambiguity it is
suggested that detectors should not signal ‘intrusion‘ and ‘fault‘ at the same time except to indicate masking. This
implies that the detector should prioritise signals, e.g. 1 Intrusion, 2 Fault, 3 Masking.
NOTE 2 When, in Table 1, an event may optionally generate signals or messages, they are as shown in this table.
NOTE 3 It is accepted that a bus system may send out dedicated signals or messages and does not necessarily
have to follow the mapping of Table 2 provided that all of the required events are signalled.
An independent signal or message may be provided instead.Alternatively total loss of power supply shall be determined by loss of communication with the detector.

4.2 Detection
4.2.1 Detection performance
The detector shall generate an intrusion signal or message when the standard or simulated
walk-test target moves at velocities and attitudes specified in Table 3. For detection across
the boundary, the walk-test distance shall be 1,5 m either side of the boundary. For detection
within the boundary, the walk-test distance shall be 3,0 m.Table 3 – General walk test velocity and attitude requirements

For grade 3 and 4 detectors, the intermittent movement shall consist of the SWT walking 1 m at a velocity of
1,0 ms then pausing for 5 s before continuing. The sequence shall be maintained until the SWT has traversed
through the entire detection area. This constitutes one walk test. The test shall be repeated in each of the
directions shown in Figure C.3.The means to detect a significant reduction in range may be met either by detectors having the appropriate
function (4.2.3) or by suitable system design. Two or more devices (e.g. a detector in conjunction with a
camera, active transmitter or additional detector), may cooperate and interconnect with the system to provide
means to detect a significant reduction of range.4.2.2 Indication of detection
An indicator shall be provided at the detector to indicate when an intrusion signal or message
has been generated. At grades 1 and 2 this indicator shall be capable of being enabled and
disabled either remotely at access level 2 and/or locally after removal of a cover which
provides tamper detection as described in Tables 1 and 4. At grades 3 and 4 this indicator
shall be capable of being enabled and disabled remotely at access level 2.4.2.3 Significant reduction of range
Grade 4 detectors shall detect significant reduction of range or coverage area due, for
example, to deliberate or accidental introduction of objects or obstructions into the coverage
area.---------------------- Page: 12 ----------------------

Range reduction along the principal axis of detection of more than 50 % shall generate a
signal or message within 180 s, according to the requirements of Table 2 and Table 3.
If additional equipment is required to detect significant reduction of range, reference shall be
made to this equipment and its operation in the manufacturer’s documentation.4.3 Operational requirements
4.3.1 Time interval between intrusion signals or messages
Detectors using wired interconnections shall be able to provide an intrusion signal or message
not more than 15 s after the end of the preceding intrusion signal or message.Detectors using wire free interconnections shall be able to provide an intrusion signal or
message after the end of the preceding intrusion signal or message within the following times:
– Grade 1 300 s;– Grade 2 180 s;
– Grade 3 30 s;
– Grade 4 15 s.
4.3.2 Switch on delay
The detector shall meet all functional requirements within 180 s of the power supply reaching
its nominal voltage as specified by the manufacturer.4.3.3 Self tests
4.3.3.1 Local self test
The detector shall automatically test itself at least once every 24 h according to the
requirements of Tables 1 and 2. If normal operation of the detector is inhibited during a local
self-test, the detector inhibition time shall be limited to a maximum of 30 s in any period of
2 h.4.3.3.2 Remote self test
A detector shall process remote self tests and generate signals or messages in accordance
with Tables 1 and 2 within 10 s of the remote self test signal being received, and shall return
to normal operation within 30 s of the remote test signal being received.4.4 Immunity to incorrect operation
The detector shall be considered to have sufficient immunity to incorrect operation if the
following requirements have been met. No intrusion signal or message shall be generated
during the tests.4.4.1 Immunity to microwave signal interference by fluorescent lights
The detector shall not generate any signals or messages due to the operation of a fluorescent
light source mounted nearby.4.5 Tamper security
Tamper security requirements for each grade of detector are shown in Table 4.
