Alarm systems - Intrusion and hold-up systems -- Part 2-7-2: Intrusion detectors - Glass break detectors (passive)

This European Standard is for passive 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 passive 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.

Ta evropski standard se uporablja za pasivne javljalnike loma stekla, nameščene na površino zgradb, določa varnostne razrede od 1 do 4 in lastnosti specifičnih in nespecifičnih kabelskih ali brezžičnih javljalnikov ter uporablja okoljske razrede od I do IV. Ta evropski standard ne vključuje zahtev za pasivne javljalnike loma stekla, nameščene na površino, ki so namenjeni za uporabo na prostem. Javljalnik mora izpolnjevati vse zahteve posameznega razreda. Poleg obveznih funkcij, ki so opredeljene v tem standardu, ima lahko javljalnik tudi dodatne funkcije, pri čemer te ne smejo negativno vplivati na pravilno delovanje obveznih funkcij. Ta evropski standard se ne uporablja za medsebojne povezave sistemov.

Overview

SIST EN 50131-2-7-2:2012/A1:2014 is a European standard issued by CLC, focusing on alarm systems specifically designed for intrusion and hold-up systems. This part-2-7-2-details requirements and specifications for passive glass break detectors, an essential type of intrusion detector that senses glass breakage events without emitting signals actively. The amendment A1, approved in 2013, updates the original 2012 standard to enhance performance criteria, immunity, event processing, and power supply behavior for these detectors. This helps ensure reliability and robustness in protecting premises against burglary or vandalism.

Key Topics

• Event Processing: The standard defines graded requirements for event handling, including mandatory and optional alarm events such as intrusion detection, masking, tampering, low power conditions, and power supply loss. It ensures detectors respond appropriately across different security grades (1 to 4).
• Masking Detection: Modifications clarify the methodology for recognizing attempts to mask or disable detector functionality, an important aspect of anti-tampering.
• Immunity Requirements: The amendment introduces precise modifications for detector immunity to various physical impacts on glass, including:
  • Soft and hard objects hitting the glass (using controlled pendulum tests)
  • Static and dynamic pressure applications to simulate environmental and accidental forces
• Power Supply Conditions: The standard updates requirements related to slow voltage changes, power supply range, and total power loss, ensuring detectors reliably signal faults before losing intrusion detection capabilities.
• Testing Protocols: Detailed testing criteria guarantee detectors maintain performance under adverse conditions, highlighting the importance of generating correct fault signals and messages to alarm control units (CIEs).

Applications

This standard applies to the design, manufacture, testing, and certification of passive glass break detectors used in security alarm systems. Typical applications include:

• Residential and commercial intrusion alarm systems, where detecting forced entry through windows or glass doors is critical.
• High-security sites requiring hold-up alarm integration with robust monitoring of glass integrity.
• Security system manufacturers ensuring compliance with European regulatory frameworks for product reliability.
• Installation and maintenance companies selecting detectors compatible with grade-based security requirements to tailor protection levels.
• System integrators enhancing intruder detection capabilities with reliable glass break sensors resistant to environmental and tampering factors.

By adhering to SIST EN 50131-2-7-2:2012/A1:2014, security professionals can provide clients with enhanced confidence in early glass break detection, reducing false alarms and improving overall system resilience.

Related Standards

• EN 50131-1: Overall requirements for intrusion and hold-up alarm systems.
• EN 50131-2-x Series: Other parts detailing different types of intrusion detectors, such as motion detectors, vibration detectors, and glass break detectors (active).
• CENELEC CLC/TC 79: Technical committee responsible for European alarm system standards, ensuring harmonization across countries.
• ISO/IEC 27001: While focused on information security, coordination with physical security standards like EN 50131 helps ensure comprehensive site protection.
• National implementations of EN 50131-2-7-2, enforced by member states for standardized alarm performance under EU directives.

Compliance with this standard is essential for manufacturers and security providers aiming to deliver trusted, standardized passive glass break detection solutions within the European market and beyond.
