Overview
IEC 62820-1-2:2017 - Building intercom systems - Part 1-2: System requirements - Building intercom systems using the internet protocol (IP) - defines technical requirements for the composition, functions, performance and test methods of IP-based building intercom systems. It is a supplement to IEC 62820-1-1 and applies to both residential and commercial building installations. The standard helps ensure consistent performance, interoperability and reliable operation of networked intercom installations.
Key topics
The standard addresses system-level requirements rather than product-level specifics. Major technical topics typically covered include:
- System composition and architecture - recommended functional blocks and component roles in an IP intercom solution (stations, door stations, controllers, servers, network interfaces).
- Functional requirements - call initiation, two-way audio (and where applicable video), paging, door release, access-control interfaces and emergency calling.
- Performance and quality - expected operational criteria such as audio/video quality, latency, availability and robustness over IP networks.
- Test methods and verification - procedures to validate functional performance, interoperability and environmental behaviour.
- System integration - guidelines for integrating intercoms with building systems (security, access control, building management) and for ensuring predictable behaviour on shared IP networks.
- Reliability and maintenance - provisioning for fault tolerance, backups, remote diagnostics and commissioning checks.
(Notes: IEC 62820-1-2 is a system requirements supplement to IEC 62820-1-1; it focuses on IP transport and system behaviour for building intercoms.)
Applications
IEC 62820-1-2 is practical for:
- System designers and integrators specifying architecture and acceptance criteria for IP intercom projects.
- Manufacturers aligning product features to system-level requirements for interoperability.
- Specifiers and consultants preparing tender documents and technical requirements for residential and commercial buildings.
- Facility managers and installers commissioning, testing and maintaining IP intercom installations.
- Test laboratories developing conformance and performance test plans.
Use cases include multi-dwelling residential entry systems, commercial office building door-entry, concierge and reception intercoms, parking/garage access stations, and integrated security/intercom solutions.
Related standards
- IEC 62820-1-1 (system requirements baseline) - IEC 62820-1-2 acts as a supplement specific to IP implementations.
- Local building codes, security and access-control standards, and network quality-of-service best practices should be considered alongside IEC 62820-1-2 when specifying or deploying IP-based intercom systems.
