SIST EN 50131-2-7-3:2012/A1:2014

• Abstract:

  This European Standard is for active surface mounted glass break detectors installed in buildings and provides for security Grades 1 to 4, specific or non-specific wired or wire-free detectors, and uses environmental classes I to IV. This European Standard does not include requirements for active surface mounted glass break detectors intended for use outdoors. A detector shall fulfil all the requirements of the specified Grade. Functions additional to the mandatory functions specified in this standard may be included in the detector, providing they do not adversely influence the correct operation of the mandatory functions. This European Standard does not apply to system interconnections.

Overview

SIST EN 50131-2-7-3:2012/A1:2014 is a European standard developed by the CLC (European Committee for Electrotechnical Standardization). It focuses on alarm systems, specifically intrusion and hold-up systems, and details requirements for active glass break detectors. This amendment applies to intrusion detectors that identify the breaking of glass, a common point of unauthorized entry in security situations. Adherence to this standard supports the consistent performance, safety, and reliability of alarm systems used throughout Europe. As part of the EN 50131 family, it enhances the detection capabilities of security systems aimed at protection against crime.

Key Topics

• Event Processing: Defines mandatory and optional events alarm detectors must process, such as intrusion attempts, tampering, masking, low supply voltage, and total power loss, differentiated by security grades.
• Detection of Masking: Clarifies the requirements for detectors to reliably identify any attempt to obscure or block the sensor.
• Immunity Testing: Establishes methods for assessing detector immunity to various disturbances, improving reliability and minimizing false alarms:
  • Soft or hard objects hitting the glass
  • Static and dynamic pressure changes
  • Wide-band noise using flat steel rulers
• Power Supply Requirements: Specifies performance under changing voltage conditions and procedures for handling total power loss, ensuring that detectors function or report faults as required.
• Environmental Conditions: Outlines environmental classifications and operational conditions, further ensuring detectors’ correct function across a range of real-world scenarios.
• System Grades: Provides event handling and immunity requirements based on system grades (Grades 1–4), allowing alignment with the necessary security level.

Applications

The standard is directly relevant to organizations and professionals involved in the design, installation, and maintenance of intrusion and hold-up alarm systems. Its typical applications include:

• Commercial Buildings: Ensuring comprehensive glass break detection in offices, retail spaces, and warehouses for property protection.
• Residential Security: Enhancing home security alarm systems, particularly for windows and glass doors prone to attack.
• Financial Institutions: Providing a reliable layer of protection in banks and similar high-risk environments.
• Critical Infrastructure: Supporting the security needs of utilities, telecommunications, and transportation hubs.
• Compliance and Certification: Serving as a benchmark for security system certification according to European and national requirements.

By following SIST EN 50131-2-7-3:2012/A1:2014, stakeholders ensure the use of high-quality, reliable, and standardized intrusion detectors, reducing the likelihood of false alarms and missed detection events in case of attempted burglary or forced entry.
