IEC 62642-2-71:2015

Overview

IEC 62642-2-71:2015 is an international standard developed by the International Electrotechnical Commission (IEC) that specifies the requirements for passive acoustic glass break detectors used as part of intrusion alarm systems in buildings. This standard defines the functional and performance criteria for these detectors, ensuring consistent reliability and efficacy in protecting property from unauthorized access by detecting the breaking of glass windows, doors, or panels.

IEC 62642-2-71:2015 applies to both wired and wire-free acoustic glass break detectors installed indoors, covering security grades 1 to 4 (see IEC 62642-1) and environmental classes I to IV (see IEC 62599-1). This standard supports manufacturers, security system integrators, and building owners aiming for robust intrusion detection through standardized components.

Key Topics

• Scope and Applicability

  • Defines requirements for passive acoustic glass break detectors in intrusion alarm systems installed inside buildings.
  • Covers both specific and non-specific, wired and wire-free detectors.
  • Addresses security grades 1 to 4 and environmental conditions classes I to IV.

• Functional Requirements

  • Specification of event detection and generation of signals or messages, including intrusion, masking, tamper, fault, and self-test events.
  • Requirements for the response time, self-testing (local and remote), and indications of detection.

• Detection and Performance

  • Detectors must reliably identify actual glass breakage events as defined by the standard.
  • Performance validation includes tests for glass breakage, hole drilling, and glass cutting.
  • Verification of coverage range, mounting locations, and compatibility with different glass types and thicknesses.

• False Alarm Immunity

  • Requirements for immunity to common false alarm sources such as small, soft, or hard objects hitting the glass, single frequency sounds, and wide band noise.
  • Detectors must not trigger alarms due to non-threatening events.

• Tamper Security

  • Mandates for resistance and detection of unauthorized access, removal from mounting surfaces, masking, and immunity to magnetic field interference.
  • Specifies torque requirements and additional anti-tamper measures depending on security grade.

• Marking and Documentation

  • Clear requirements for product marking, identification, and user documentation to ensure traceability and proper usage.

• Testing Procedures

  • Standardized test methods for functionality, immunity, environmental conditions, and durability.
  • Reference to standard test setups and glass types for unified evaluation.

Applications

Implementing IEC 62642-2-71:2015 delivers tangible benefits in security and risk management across various sectors:

• Security System Design

  • System integrators and designers rely on the standard to select detectors with proven performance, reducing vulnerabilities due to glass breakage.

• Compliance and Certification

  • Facilities meeting IEC 62642-2-71:2015 demonstrate adherence to international best practices, often a prerequisite for insurance and regulatory compliance.

• Product Development

  • Manufacturers use the standard as a benchmark for developing reliable, market-ready acoustic glass break detectors compatible with global alarm systems.

• Building Security Upgrades

  • Property owners and managers use IEC-compliant detectors to enhance intrusion detection in both new installations and security retrofits.
