Building intercom systems - Part 1-1: System requirements - General

IEC 62820-1-1:2016 specifies the technical requirements for the composition, functions, performance, and test methods of general building intercom systems. This part is applicable to the general intercom systems for building entry in residential or commercial buildings. General building intercom systems have been classified into two grades: Grade 1 adopts lower requirements to cover door-entry-systems not used for relevant security applications while grade 2 adopts higher requirements for building intercom systems for security applications. Each grade may adopt different functional and performance requirements, test methods and normative references.

Systèmes d'interphone de bâtiment - Partie 1-1: Exigences du système - Généralités

L'IEC 62820-1-1:2016 spécifie les exigences techniques relatives à la composition, aux fonctions, aux performances, et aux méthodes d'essai des systèmes généraux d'interphone de bâtiment. La présente partie est applicable aux systèmes généraux d'interphone pour entrée de bâtiments résidentiels ou commerciaux. Les systèmes généraux d'interphone de bâtiment ont été classés en deux niveaux. Le niveau 1 adopte des exigences moins strictes pour couvrir les systèmes de contrôle d'accès non utilisés pour les applications de sécurité correspondantes, le niveau 2 s'appuyant sur des exigences plus strictes pour les systèmes d'interphone de bâtiment destinés aux applications de sécurité. Chaque niveau peut s'appuyer sur des exigences fonctionnelles et de performances, des méthodes d'essai et des références normatives différentes.

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 62820-1-1 has been prepared by IEC technical committee 79: Alarm

and electronic security systems.
The text of this standard is based on the following documents:
FDIS Report on voting
79/559/FDIS 79/563/RVD

Full information on the voting for the approval of this standard can be found in the report on

voting indicated in the above table.

This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to

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

INTRODUCTION

This part of IEC 62820 specifies the technical requirements for building intercom systems and

equipment used for building entry. Building intercom systems can function independently and

may be extendable to support building security management functions, e.g. extendable with

security management unit (SMU) operated by security staff (door-man, concierge,

security-guard, porter, etc.), or in conjunction with other systems as per the security

requirements of the building. It may consist of: Visitor call unit (VCU), user receiver unit (URU),

SMU, power supply, auxiliary device as well as interface-unit to other security-systems.

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 – IP building intercom systems
Part 2: Requirements for advanced security building intercom systems
Part 3-1: Application guidelines – General
Part 3-2: Application guidelines – Advanced security building intercom systems

The Part 1-1 of IEC 62820 is based on Chinese standard GB/T 31070.1-2014 and European

standard EN 50486:2008.

BUILDING INTERCOM SYSTEMS –
Part 1-1: System requirements – General
1 Scope

This Part of IEC 62820 specifies the technical requirements for the composition, functions,

performance, and test methods of general building intercom systems.

This part is applicable to the general intercom systems for building entry in residential or

commercial buildings.

Door-Entry-System (DES) is a simple kind of convenient Building-Intercom-System (BIS) mainly

for user’s comfort. This document has classified the general building intercom systems into two

grades in Part 1-1. Grade 1 adopts lower requirements to cover DES not used for relevant

security applications while grade 2 adopts higher requirements for building intercom systems for

security applications. Each grade may adopt different functional and performance requirements,

test methods and normative references.

NOTE The different requirements between grade 1 and grade 2 are summarized in Table C.1.

2 Normative references
