IEC 62820-2:2017 PDF

Overview

IEC 62820-2:2017 establishes comprehensive requirements for advanced security building intercom systems (ASBIS) used in modern buildings. This international standard by the International Electrotechnical Commission (IEC) details the composition, functional capabilities, performance criteria, and rigorous testing protocols for ASBIS installations. Specifically designed for high-security environments, these intercom systems facilitate rapid and reliable voice communication during emergencies, enable instant danger warnings, and ensure swift notifications to emergency or intervention teams. Prior to system design and deployment, the standard emphasizes the importance of risk assessment and clearly defining protection targets to tailor solutions effectively.

Key Topics

The IEC 62820-2:2017 standard covers a broad scope of technical and operational features essential for advanced building intercom systems, including:

• Functional Requirements

  • Call management (standard, emergency, high-priority, and help calls)
  • Voice communication modes: half duplex, full duplex, and voice-switched duplex
  • Unlocking functions and security control
  • Audio-visual indicators for call and status notifications
  • Support for direct communication between security units and master stations
  • Automatic detection of aggressive events such as screams, glass breakage, and gunshots
  • System redundancy for high availability
  • Environmental noise cancellation for clear communication

• Performance Criteria

  • Acoustic parameters such as frequency response, distortion, and signal-to-noise ratio
  • Audio quality measurements including speech transmission index (STI)
  • Codec performance including delay and switching times
  • System status, event, and fault monitoring to ensure operational integrity

• Security and Access Control

  • Network security to protect communication channels
  • User authentication and authorization for service personnel and administrators
  • Interconnection security and data integrity
  • Access control mechanisms to prevent unauthorized use

• Testing Methods

  • Standardized procedures for assessing acoustic levels, frequency response, and audio quality onsite and in laboratory settings
  • Methods to evaluate overall system reliability and functional responsiveness

Applications

IEC 62820-2:2017 is vital for organizations and professionals involved in the design, installation, and maintenance of building intercom systems where advanced security communication is critical. Typical application scenarios include:

• Emergency Communication Systems in commercial complexes, hospitals, and educational institutions where fast and reliable voice alerting can save lives.
• High-Security Residential Buildings requiring robust intercom functionalities to manage visitor access and respond to threat situations effectively.
• Public Service Facilities like police stations, fire departments, and intervention centers relying on precise and instantaneous voice communication.
• Critical Infrastructure Sites such as airports, power plants, and government buildings integrating intercom systems with broader security surveillance networks.

The standard guides the creation of systems capable of rapid danger message verification, enhanced voice clarity under noisy conditions, and seamless integration with emergency service protocols.

Related Standards

Professionals utilizing IEC 62820-2:2017 for ASBIS implementations should consider associated IEC and international standards to foster interoperability and compliance:

• IEC 62820-1 – General requirements and definitions for building intercom systems, providing foundational concepts.
• IEC 60417 – Graphical symbols for use on equipment, referenced for consistent pictograms in system interfaces.
• ISO 7010 – Standard for safety signs including symbols related to security and emergency actions.
• IEC 62368-1 – Safety requirements for audio and video equipment, applicable to intercom hardware components.
• Other IEC standards on network security, electrical safety, and audio performance complement the ASBIS framework.

By following IEC 62820-2:2017 along with these relevant standards, stakeholders ensure robust, secure, and high-performance intercom systems suited for modern building security needs.
