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

This part 2-5 of the IEC 62642 series of standards gives requirements for combined passive

infrared and ultrasonic 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/systems

This standard is for combined passive infrared and ultrasonic 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, at the same time, to emit ultrasonic radiation over the area being protected, and

analyse signals that are returned, 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 standard 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.

1 Scope

This part of the IEC 62642 is for combined passive infrared and ultrasonic 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

standard does not include requirements for combined passive infra red and ultrasonic

detectors intended for use outdoors.
A detector should 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.

The International Standard does not apply to system interconnections.

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.
---------------------- Page: 11 ----------------------
– 10 – 62642-2-5 Ó IEC:2010

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.

Velocity N/A N/A N/A 1,0 ms
Attitude N/A N/A N/A Upright

For grades 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.
---------------------- Page: 12 ----------------------
62642-2-5 Ó IEC:2010 – 11 –
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.

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 wirefree 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.
