WG 13 - TC 79/WG 13

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.

IEC 62820-3-1:2017 gives guidelines for planning, installation, commissioning, operation and maintenance of Building Intercom Systems (BIS), for use in security applications. The different technical requirements for BIS are specified in IEC 62820-1-1 and IEC 62820-1-2. The objectives of this document are to:
- provide a framework to assist system integrators, installers, consultant engineers and system owners in establishing their requirements;
- assist specifiers and system owners in determining the appropriate equipment required for a given application.

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.

IEC 62820-1-2:2017 specifies the technical requirements for the composition, functions, performance and test methods of building intercom systems using the internet protocol (IP), and it is a supplement to IEC 62820-1-1. This document is applicable to the IP building intercom systems for both residential and commercial buildings.

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.
