IEC 62642-2-72:2015

Overview

IEC 62642-2-72:2015 is an international standard published by the International Electrotechnical Commission (IEC) that specifies requirements for passive surface-mounted glass break detectors used in alarm systems. These detectors are designed to identify the sound or shock of glass breaking, providing a vital intrusion detection method for buildings. This standard addresses various performance and operational criteria across different security grades (1 to 4) and environmental classes (I to IV), supporting both wired and wireless installations.

By defining stringent functional, electrical, environmental, and tamper-resistance criteria, IEC 62642-2-72:2015 aims to ensure reliability, reduce false alarms, and enhance security system effectiveness in residential, commercial, and industrial applications.

Key Topics

• Scope and Applicability: Covers passive glass break detectors installed on building surfaces for intrusion and hold-up alarm systems.
• Security Grades: Supports security levels 1 to 4, aligning with IEC 62642-1, to guide suitability based on risk and application.
• Environmental Classes: Defines detector operability under varying environmental conditions according to IEC 62599-1, ensuring performance in diverse climates and settings.
• Functional Requirements:
  • Event processing and detection performance.
  • Immunity to false alarms caused by small, soft, or hard objects hitting the glass.
  • Resistance to static and dynamic pressure and wideband noise.
• Tamper Security:
  • Detection of unauthorized access or removal.
  • Masking detection and immunity to magnetic interference.
• Electrical Requirements:
  • Voltage consumption, input voltage tolerance, and ripple immunity.
• Testing and Verification:
  • Detailed methods for basic detection, immunity to false alarms, tamper resistance, electrical performance, and environmental durability.
• Marking and Documentation: Specifies clear labeling and comprehensive user documentation to facilitate proper installation and maintenance.

Applications

IEC 62642-2-72:2015 glass break detectors are essential components in security alarm systems for various environments:

• Residential Buildings: Protect windows and glass doors to alert homeowners of forced entry.
• Commercial Properties: Secure storefronts, offices, and glass partitions, integrating with intruder alarm frameworks to control access.
• Public and Industrial Facilities: Prevent vandalism and unauthorized access to critical areas, ensuring higher security confidence.
• Wireless and Wired Systems: Designed for flexible installation whether in legacy wired security setups or modern wireless networks, enhancing adaptability.
• Security Graded Systems: Tailored choice of detectors appropriate for varied threat levels and insurance compliance requirements.

By adopting this IEC standard, system integrators and manufacturers can assure that glass break detectors meet internationally recognized benchmarks for reliability, sensitivity, and tamper resistance while maintaining operational efficiency even in challenging environments.
