Overview
IEC 62820-1-1:2016 is an international standard published by the International Electrotechnical Commission (IEC) that specifies the general system requirements for building intercom systems. This standard outlines the technical requirements, functional capabilities, performance criteria, and recommended test methods for intercom systems intended for building entry in both residential and commercial environments. The standard classifies intercom systems into two grades: Grade 1 for basic door-entry systems without security functions, and Grade 2 for intercom systems supporting higher security requirements. By adhering to IEC 62820-1-1:2016, manufacturers, installers, and building managers can ensure interoperability, reliability, and basic security for building communication systems.
Key Topics
-
System Composition: The standard defines the essential components of building intercom systems, including Visitor Call Units (VCU), User Receiver Units (URU), Security Management Units (SMU), power supplies, and interfaces to auxiliary/security devices.
-
Functional Requirements:
- 2-way speech communication between units.
- Electronic unlocking for controlled entrances.
- Audible and/or visible call and response alerts.
- Nighttime operability, with higher requirements for systems used in security applications.
- Anti listen-in protections for confidential communication (Grade 2).
- Video functions, such as image display and optional image recording and replaying.
-
Performance Requirements:
- Audio Characteristics: Standards for acoustic pressure level, loudness rating, sensitivity, frequency response, channel noise, and acoustic safety.
- Video Characteristics: Image resolution, color reproduction, focus distance, and adaptability to environmental lighting.
- Environmental Adaptability: Requirements for operating under different environmental and mechanical conditions.
- Safety and Electromagnetic Compatibility (EMC): Ensures system robustness against faults, electromagnetic interference, and includes marking and structural integrity criteria.
-
Test Methods: Includes guidelines for testing system functions, audio/video quality, environmental conditions, safety features, and EMC compliance.
Applications
IEC 62820-1-1:2016 is designed for use in a wide range of applications where building intercom systems are necessary for access control and communication:
- Residential Buildings: Facilitating secure and convenient entry for residents and visitors, ensuring basic communication and controlled access.
- Commercial Buildings: Enhancing security by providing controlled entry to office complexes, retail establishments, or multi-use properties.
- Security Applications: Grade 2 systems are particularly suitable for buildings requiring higher levels of safety and privacy, such as schools, hospitals, data centers, and managed residential complexes.
- New Builds and Retrofits: The standard provides clear guidelines that support the integration of modern intercom functions in both new construction and the upgrading of existing systems.
- Integration with Security Systems: IEC 62820-1-1:2016 enables seamless interfacing between building intercoms and broader security management systems, offering scalability and future-proofing.
