Building intercom systems - Part 3-2: Application guidelines - Advanced security building intercom systems

IEC 62820-3-2:2018 describes the basic application requirements for Advanced Security Building Intercom Systems (ASBIS) in public and private buildings with advanced safety and security needs. ASBIS are also used to meet the requirements of the Local Regulations of Workplace Safety and/or other relevant local regulations, in particular, protecting the life and limb of employees and all persons in the building, taking into account the inclusion of people with disabilities (e.g to achieve barrier-free access or calls for help) where required by local applicable law. The recommendations and requirements of IEC 62820-3-1 are mandatory for this document.

Systèmes d'interphone de bâtiment - Partie 3-2: Lignes directrices d'application - Systèmes d'interphone de bâtiment à sécurité avancée (ASBIS)

L'IEC 62820-3-2:2018 décrit les exigences d'application de base des systèmes d'interphone de bâtiment à sécurité avancée (ASBIS) installés dans les bâtiments publics ou privés ayant des besoins en matière de sûreté et de sécurité avancées. Les systèmes ASBIS sont également utilisés pour satisfaire aux exigences des règlements locaux en matière de sécurité au travail et/ou d'autres règlements locaux pertinents, en particulier, la protection de la vie et de l'intégrité physique des employés et de toutes les personnes présentes dans le bâtiment, sans oublier les personnes handicapées (pour prévoir un accès sans obstacle ou des moyens d'appeler à l'aide, par exemple) si cela est exigé par la loi locale applicable. Les recommandations et exigences de l'IEC 62820-3-1 sont obligatoires pour la présente norme.

Notranja komunikacija v stavbah - 3-2. del: Smernice za uporabo - Napredni varnostni sistemi notranjih komunikacij v stavbah

Ta del standarda IEC 62820 opisuje osnovne zahteve za uporabo naprednih varnostnih sistemov notranjih komunikacij v stavbah (ASBIS) v javnih in zasebnih stavbah, ki potrebujejo napredno varnost in zaščito. Napredni varnostni sistemi notranjih komunikacij v stavbah se uporabljajo tudi za izpolnjevanje zahtev lokalnih predpisov za varnost na delovnem mestu in/ali drugih ustreznih lokalnih predpisov, zlasti za zaščito življenja in udov zaposlenih ter vseh oseb v stavbi, pri čemer se upoštevajo tudi invalidi (npr. za zagotovitev neoviranega dostopa ali klica na pomoč), kjer to zahteva veljavna lokalna zakonodaja.
Ta dokument se uporablja za načrtovanje, nameščanje, usposabljanje za zagon, predajo, delovanje in vzdrževanje naprednih varnostnih sistemov notranjih komunikacij v stavbah ter za prenos zvočnih sporočil v sili, o nevarnosti in nesrečah in/ali drugih operativnih znamenj podporni službi z namenom oddaljenega ocenjevanja ter izvedbe ustreznih intervencijskih, zaščitnih in reševalnih ukrepov.
Prav tako je mogoč prenos dodatnih informacij, sistem pa je mogoče uporabljati pri vsakodnevnem delu za vse komunikacijske potrebe. Napredni varnostni sistemi notranjih komunikacij v stavbah so visoko razpoložljivi tudi za nadzor končnih enot in sistema.
Napredni varnostni sistemi notranjih komunikacij v stavbah se uporabljajo za klice v sili, o nevarnosti in nesrečah, preverjanje na podlagi glasovne komunikacije, opozarjanje na nevarnost, hitro obveščanje odgovornih zasilnih/intervencijskih služb ter pošiljanje glasovnih navodil in/ali drugih operativnih znamenj za nadaljnje ukrepanje. Za določitev ustrezne zasnove je treba najprej oceniti tveganje in opredeliti cilj zaščite. Na podlagi obvladovanja tehničnega tveganja (TRM) in obvladovanja organizacijskega tveganja (ORM) je treba v povezavi z ustreznimi sistemskimi zahtevami izdelati skupno strategijo poteka dela za doseganje ostalih tveganj. Ta dokument podaja zahteve za obvladovanje tehničnega tveganja ter pripombe o obvladovanju organizacijskega tveganja in priporočila zanj.
Ta dokument za uporabo naprednih varnostnih sistemov notranjih komunikacij v stavbah med drugim opisuje tehnološke procese in odgovornosti, povezane s podporo vseh procesov, ki vključujejo zaznavanje dogodka
(klic obiskovalca, klic v sili, nesreča, nevarnost) in njegovo obravnavo. Zajema obvladovanje tehničnega tveganja, opredeljene cilje zaščite in organizacijske postopke ter potrebne zahteve za datoteko obvladovanja tehničnega tveganja. Ta dokument opredeljuje tri različne varnostne/zaščitne razrede in njihove zahteve proizvoda. Za izbiro proizvodov, ki jih je v okviru naprednih varnostnih sistemov notranjih komunikacij v stavbah mogoče uporabiti kot tehnične vire, je odgovorno uporabljeno obvladovanje tehničnega tveganja.
Ta dokument skupaj z naprednimi varnostnimi sistemi notranjih komunikacij v stavbah opredeljuje tudi povezane naloge, odgovornosti in dejanja. Ti sestavljajo celovit postopek obvladovanja tehničnega tveganja z namenom izpolnjevanja ciljev zaščite za varnost/zaščito osebja, učinkovitost in uspešnost sistema ter varnost podatkov in sistema. Ta dokument ne določa stopenj tveganja. Zlasti ne opredeljuje sprejemljivih ostalih tveganj. Obvladovanje tehničnega tveganja in obvladovanje organizacijskega tveganja sta z vidika splošnega obvladovanja tveganja (glej dodatek C) enako pomembna.

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 62820-3-2 has been prepared by IEC technical committee 79:
