EN 50131-2-7-1:2012/A2:2016

Overview

EN 50131-2-7-1:2012/A2:2016 is a key European standard issued by CENELEC (CLC) concerning alarm systems, specifically focusing on intrusion and hold-up systems and their acoustic glass break detectors. This amendment modifies select chapters of EN 50131-2-7-1:2012, improving test methodologies for glass break detectors and updating requirements related to immunity performance. The updated requirements, particularly in Chapter 6.7.4 and Annex B, support consistent product testing and reliable intrusion detection in modern security systems.

Key Topics

• Scope of Amendment:
  The amendment introduces changes to key testing procedures, allowing products to meet updated compliance for acoustic glass break detectors used in intrusion detection.

• Testing Procedure Adjustments:

  • Angle Change for Hard Object Testing:
    • The angle for testing the immunity of detectors to hard objects hitting glass is revised to 27° ± 1°, replacing the previous 60° ± 5° requirement.
  • Glass Pane Specification Update:
    • The standard size for immunity test glass panes remains 800 mm by 1 m, but the thickness is increased from 4 mm ± 1 mm to 6 mm ± 1 mm, maintaining the requirement for framed, standard plate glass.

• Enhanced Reliability:
  By precisely defining the physical parameters for test conditions, the amendment fortifies the repeatability and comparability of detector performance across the industry.

Applications

EN 50131-2-7-1:2012/A2:2016 is essential for manufacturers, installers, and specifiers of security alarm systems who require reliable intrusion detection technology. Its practical benefits include:

• Security System Design:
  • Ensures that acoustic glass break detectors are rigorously tested for immunity against false alarms caused by hard objects with defined impact angles and glass criteria.
  • Supports architects, engineers, and facility managers in selecting compliant detectors for commercial, residential, and industrial properties.
• Product Certification and Testing:
  • Provides manufacturers with precise criteria for product development and third-party testing, streamlining the path to European market access.
  • Facilitates product differentiation through compliance with up-to-date security standards.
• Regulatory Compliance:
  • Assists security integrators and consultants with documentation required for regulatory and insurance purposes, reflecting adherence to current EU best practices for intrusion detection systems.
