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

Overview

SIST EN 50131-2-7-1:2012/A2:2016 is a vital European standard focused on alarm systems, specifically covering intrusion and hold-up systems and targeting acoustic glass break detectors. Developed by CLC/TC 79 "Alarm systems," this amendment A2 updates the original 2012 standard by refining test methods to ensure detectors perform reliably under more stringent and realistic conditions. It supports enhanced security measures against unauthorized access through glass entry points by defining immunity and detection requirements for glass break detectors.

Key Topics

• Scope Update: The amendment revises specific chapters to allow products passing tests based on newly defined criteria in Annex 6.7.4 and Annex B.
• Immunity to Hard Object Impact:
  • The testing angle for hard objects hitting glass has been changed from 60° ± 5° to 27° ± 1°, making defect resistance tests more representative of real-world scenarios.
• Glass Type Specifications:
  • The standard immunity glass pane used for testing is updated from 4 mm ± 1 mm thickness to 6 mm ± 1 mm, reflecting stronger glass commonly employed in security applications.
• Harmonization: As a European standard amendment, this document mandates compliance across all CENELEC member states, enhancing consistency and interoperability of acoustic glass break detectors across Europe.

Applications

• Intrusion Detection Systems: SIST EN 50131-2-7-1:2012/A2:2016 guides manufacturers and installers of acoustic glass break detectors, ensuring products reliably detect break-ins through glass windows or doors.
• Security System Design: The revised testing requirements help designers select detectors verified to resist false alarms due to impacts from hard objects, improving system accuracy and robustness.
• Compliance and Certification: Security device manufacturers aiming for CE marking in Europe utilize this standard to demonstrate conformity with recognized alarm system performance and safety standards.
• Commercial and Residential Security: Integral in safeguarding homes, offices, banks, and retail environments by detecting intrusions swiftly and reducing vulnerability to forced glass entry.

• CENELEC Directives: This amendment aligns with CENELEC internal regulations mandating uniform implementation of standards across member states.
• Alarm System Performance Standards: Complements EN 50131-1 and other part 2 standards that specify requirements for other types of detectors such as motion sensors, magnetic contacts, and smoke detectors.
