Overview

EN 50131-1:2006/A1:2009 is the CENELEC amendment to EN 50131-1:2006 that specifies system requirements for intrusion and hold-up alarm systems (I&HAS). Approved in May 2009, this amendment refines definitions, functional requirements and operational rules for compliant alarm installations across supervised premises. It targets manufacturers, integrators, security consultants and compliance teams working with graded alarm systems.

Key Topics

• Scope and applicability: Amendment A1 modifies terminology and clarifies requirements relevant to system-level behaviour of I&HAS, including interactions with alarm transmission systems and alarm receiving centres.
• Definitions and abbreviations: Updated definitions for key terms (e.g., alarm transmission system, subsystem, supervised premises transceiver (SPT), event recording, inhibit/override) help ensure consistent interpretation across components and national implementations.
• Security grading and access levels: The standard preserves graded system requirements (Grades 1–4) and defines access levels (1–4) for user functions such as setting/unsetting, restore, inhibit/isolate and program changes. Additional rules clarify when optional functions must meet the requirements of a claimed grade.
• Indications and notifications: Requirements cover mandatory and optional local indications (set/unset state, zone identification, pending/alert indications) and remote notification practices. A key operational rule requires a warning device or indicator to operate for a minimum time (e.g., 30 s) before remote notification in certain unsetting procedures.
• Tamper detection and monitoring: The amendment details tamper detection expectations for components (CIE/ACE/SPT/WD/PS, detectors, junction boxes), means to be detected, and exceptions for portable devices or specific component types.
• Interconnections and power: Monitoring of interconnections is addressed with stated exceptions for portable devices; power supply types and fault handling are part of system-level considerations.

Applications

This amendment is practical for:

• Manufacturers ensuring system-level compliance for I&HAS as part of product families.
• Security integrators implementing graded alarm solutions that must meet access, indication and notification rules.
• Risk assessors and facility managers requiring clear operational behaviours (e.g., tamper responses, alarm transmission path independence) for premises protection.

Benefits include clearer definitions that reduce ambiguity in installations, guidance on access controls to protect system integrity, and enhanced interoperability with alarm transmission systems (ATS).

Related Standards

• EN 50136-1-1 - referenced for alarm transmission system performance and general ATS requirements.
• EN 61000-6-3 (EMC) - emission standard for residential, commercial and light-industrial environments (referenced in amendment).

Additional context: amendment A1 was prepared by CENELEC TC 79 (Alarm systems) and provides national implementation dates and guidance for endorsement. For full compliance and implementation details, consult the complete EN 50131-1:2006/A1:2009 document and associated component standards.
