Overview
SIST EN IEC 62820-1-1:2026 – "Building intercom systems - Part 1-1: System requirements - General" – is a standard developed by the Slovenian Institute for Standardization (SIST) in alignment with the IEC 62820-1-1:2026. This international standard sets out the technical and performance requirements for general building intercom systems, focusing on both residential and commercial building entry applications. It details the essential components, functions, test methods, and classification of building intercom systems (BIS), ensuring reliable and secure communication at building entry points.
Key Topics
- Scope and Application: The standard outlines requirements applicable to general building entry intercom systems, suitable for homes, offices, and commercial structures.
- System Grades: Two grades are defined:
- Grade 1: Basic intercom and door entry systems, not intended for security-critical applications.
- Grade 2: Intercom systems utilized for security applications, with enhanced functional and performance criteria.
- System Functions:
- Call and speech functions for 2-way communication between entry points and internal locations.
- Unlocking functions for remotely operating entrance locks.
- Video and image handling (optional).
- Operational indications for user guidance.
- Anti-listen-in features for privacy (Grade 2).
- Performance Criteria:
- Audio quality (acoustic pressure, loudness, sensitivity, noise, and distortion).
- Video characteristics (resolution, color accuracy, environmental adaptability).
- Electromagnetic compatibility and mechanical protection (IP and IK codes).
- Environmental adaptability for varying installation conditions.
- Safety and protection under fault conditions.
Applications
Building intercom systems standardized under IEC 62820-1-1:2026 are integral to modern residential, multi-dwelling, and commercial buildings. Typical applications include:
- Residential Apartments: Providing secure communication between residents and visitors, remote door unlocking, and optional video verification at entry points.
- Commercial Offices: Facilitating visitor management, reception communication, and integration with building security infrastructure.
- Mixed-use Buildings: Supporting both comfort and security for occupants by allowing graded system selection based on risk and operational needs.
- Institutional Buildings: Integration with alarm and security systems for enhanced safety and controlled access in schools, hospitals, and public sector facilities.
This standard enables industrial designers, engineers, and facility managers to specify compliant intercom systems based on required security levels, environmental conditions, and user needs. It also supports manufacturers and integrators in demonstrating product compliance through standardized test methods and requirements.
