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.

International Standard IEC 62642-2-2 has been prepared by IEC technical committee 79:

Alarm and electronic security systems.

The committee has decided that the contents of this publication will remain unchanged until

the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data

related to the specific publication. At this date, the publication will be

INTRODUCTION

This part 2-2 of the IEC 62642 series of standards gives requirements for passive infrared

detectors used in intrusion and hold-up alarm systems. The other parts of this series of

standards are as follows:
Part 1 System requirements
Part 2-2 Intrusion detectors – Passive infrared detectors
Part 2-3 Intrusion detectors – Microwave detectors
Part 2-4 Intrusion detectors – Combined passive infrared / microwave detectors
Part 2-5 Intrusion detectors – Combined passive infrared / ultrasonic detectors
Part 2-6 Intrusion detectors – Opening contacts (magnetic)
Part 2-71 Intrusion detectors – Glass break detectors – Acoustic
Part 2-72 Intrusion detectors – Glass break detectors – Passive
Part 2-73 Intrusion detectors – Glass break detectors – Active
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

This International Standard deals with passive infrared 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 detect the broad spectrum infrared radiation emitted by 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 International Standard is only concerned with the requirements and tests for the detector.

Other types of detector are covered by other documents identified as in IEC 62642-2 series.

Part 2-2: Intrusion detectors –
Passive infrared detectors
1 Scope

This part of the IEC 62642 is for passive infrared detectors installed in buildings and provides

for security grades 1 to 4 (see IEC 62642-1), specific or non-specific wired or wire-free

detectors, and uses environmental classes I to IV (see IEC 62599-1). This International

Standard does not include requirements for passive infrared detectors intended for use

outdoors.
A detector shall fulfil all the requirements of the specified grade.

Functions additional to the mandatory functions specified in this standard may be included in

the detector, providing they do not influence the correct operation of the mandatory functions.

This International Standard does not apply to system interconnections.

An independent signal or message may be provided instead.

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.

Alternatively total loss of power supply shall be determined by loss of communication

with the detector.

When, in Table 1, an event may optionally generate signals or messages, they shall be as

shown in this table.
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
