Building intercom systems - Part 2: Requirements for advanced security building intercom systems (ASBIS)

IEC 62820-2:2017 specifies the technical requirements for the composition, function, performance and testing methods of Advanced Security Building Intercom Systems. This document is applicable for intercom systems used for any advanced security communication in buildings. Advanced security building intercom systems (ASBIS) are used for rapid emergency and danger messages verification by voice communication, warning of a danger, rapid notification of the responsible emergency services/intervention services and for sending instructions on how to proceed. The requirement for a suitable concept is prior risk assessment and a definition of the protection target.

Systèmes d'interphone de bâtiment - Partie 2: Exigences pour les systèmes d'interphone de bâtiment à sécurité avancée (ASBIS)

L'IEC 62820-2:2017 spécifie les exigences techniques relatives à la composition, aux fonctions, aux performances et aux méthodes d'essai des systèmes d'interphone de bâtiment à sécurité avancée. Le présent document s'applique aux systèmes d'interphone utilisés pour la communication à sécurité avancée dans les bâtiments. Les systèmes d'interphone de bâtiment à sécurité avancée (ASBIS) sont utilisés pour la vérification rapide de messages d'urgence et de danger par communication vocale, la mise en garde contre un danger, la notification rapide des services d'urgence/services d'intervention concernés et pour envoyer des instructions sur la conduite à adopter. L'exigence pour un concept adapté consiste en une évaluation préalable du risque et en une définition de la cible de la protection.

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 62820-2 has been prepared by IEC technical committee 79: Alarm

and electronic security systems.
The text of this International Standard is based on the following documents:
FDIS Report on voting
79/588/FDIS 79/590/RVD

INTRODUCTION

The IEC 62820 series of standards set out the technical requirements for the composition,

functions, performance, test methods of building intercom systems for building entry and

application guidelines and consist of five parts:
Part 1-1: System requirements – General;

Part 1-2: System requirements – Building intercom systems using the internet protocol (IP);

Part 2: Requirements for advanced security building intercom systems (ASBIS);
Part 3-1 : Application guidelines – General;
Part 3-2 : Application guidelines – Advanced security building intercom systems.

IEC 62820-2 specifies higher security requirements, to be used in buildings with advanced

security needs that additionally or alternatively apply in respect of those in IEC 62820-1-1 and/or

IEC 62820-1-2 which give basic requirements for building intercom systems.

Additional requirements and recommendations are those described in IEC 62820-2, but they

are not covered by IEC 62820-1-1 neither IEC 62820-1-2.

Requirements and recommendations described by IEC 62820-2 have precedence, if also

described in IEC 62820-1-1 and/or IEC 62820-1-2.

BUILDING INTERCOM SYSTEMS –
Part 2: Requirements for advanced security
building intercom systems (ASBIS)
1 Scope

This part of IEC 62820 specifies the technical requirements for the composition, function,

performance and testing methods of Advanced Security Building Intercom Systems.
This document is applicable for intercom systems used for any advanced security
communication in buildings.

Advanced security building intercom systems (ASBIS) are used for rapid emergency and danger

messages verification by voice communication, warning of a danger, rapid notification of the

responsible emergency services/intervention services and for sending instructions on how to

proceed. The requirement for a suitable concept is prior risk assessment and a definition of the

protection target.
A Security management unit (SMU) is a necessary part of an ASBIS.

The type of building and the usage of a building have influence on the risk calculation. In this

document, the relevant functions and performances are divided into three grades. According to

the results of the risk calculation, the security needs will be covered by an individual system

profile.

NOTE 1 Examples of typical profiles and each grades are defined in IEC 62820-3-2, where a risk calculation is

required.

NOTE 2 The application of this document does not dispense to comply with the public national regulations

concerning emergency systems.

NOTE 3 Systems for emergency purposes can be the subject of approval by local authorities.
