Alarm systems - Intrusion and hold-up systems - Part 4: Warning devices

IEC 62642-4:2010 includes requirements for warning devices used for notification in intrusion and hold up alarm systems installed in buildings. Four grades of warning device are described corresponding to each of the four security grades given in IEC 62642-1. Requirements are also given for four environmental classes covering applications in internal and outdoor locations as specified in IEC 62599-1.

Systèmes d'alarme - Systèmes d'alarme contre l'intrusion et les hold-up - Partie 4: Dispositifs d'avertissement

La CEI 62642-4:2010 comporte des exigences sur les dispositifs d'avertissement utilisés pour la notification dans les systèmes d'alarme contre l'intrusion et les hold-up installés dans les bâtiments. Quatre grades de dispositifs d'avertissement sont décrits, correspondant aux quatre grades de sécurité indiqués dans la CEI 62642-1. Des exigences sont également données pour les quatre classes d'environnement qui couvrent les applications situées à l'intérieur et à l'extérieur, tel que spécifié dans la CEI 62599-1.

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 62642-4 has been prepared by IEC technical committee 79: Alarm

and electronic security systems.
This standard is based on EN 50131-4 (2009).
The text of this standard is based on the following documents:

intrusion and hold up alarm systems installed in buildings. Four grades of warning device are

described corresponding to each of the four security grades given in IEC 62642-1.

Requirements are also given for four environmental classes covering applications in internal

and outdoor locations as specified in IEC 62599-1.

4 General considerations

This standard considers two different categories of warning device, remotely powered and self

powered devices.

Self powered warning devices are classified into one of four types, dependent upon the

recharge characteristics of the storage device and the source of recharge power. These four

types are defined in Table 8.
5 Requirements
5.1 Functional
5.1.1 Response

Depending upon the grade, warning devices shall have the functionality as defined in Table 1.

Where a function is provided, the warning device shall operate in accordance with the

requirements of Table 2.

The provision of a fault signal or message is not mandatory for all grades, see Table 1.

At least one of these actions shall occur at the warning device. For grade 3 and grade 4 warning devices, if the

loss of remote power source can be shown to be caused by a fault then a fault signal is generated, otherwise a

tamper signal is generated.

At least one of these actions shall occur at the warning device. For grade 3 and grade 4 warning devices, if the

loss of trigger command integrity can be shown to be caused by a fault then a fault signal is generated,

otherwise a tamper signal shall be generated.

The response to a remote test pass is different from the response to a remote test fail.
