Alarm systems - Intrusion and hold-up systems - Part 1: System requirements

This European Standard specifies the requirements for Intrusion and Hold-up Alarm Systems installed in buildings using specific or non-specific wired interconnections or wire-free interconnections. These requirements also apply to the components of an I&HAS installed in a building which are normally mounted on the external structure of a building e.g. ancillary control equipment or warning devices. The standard does not include requirements for exterior I&HAS. This standard specifies performance requirements for installed I&HAS but does not include requirements for design, planning, installation, operation or maintenance. These requirements also apply to I&HAS sharing means of detection, triggering, interconnection, control, communication and power supplies with other applications. The functioning of an I&HAS shall not be adversely influenced by other applications. Requirements are specified for I&HAS components where the relevant environment is classified. This classification describes the environment in which an I&HAS component may be expected to function as designed. When the requirements of the four environmental classes are inadequate, due to the extreme conditions experienced in certain geographic locations, special national conditions are given in Annex A. General environmental requirements for I&HAS components are described in Clause 7. The requirements of this European Standard also apply to IAS and HAS when these systems are installed independently. When an I&HAS does not include functions relating to the detection of intruders, the requirements relating to intrusion detection do not apply. When an I&HAS does not include functions relating to hold-up, the requirements relating to hold-up do not apply. NOTE Unless otherwise stated the abbreviation I&HAS is intended to also mean IAS and HAS.

Overview

EN 50131-1:2006/A3:2020 is a comprehensive European Standard specifying system requirements for Intrusion and Hold-up Alarm Systems (I&HAS) installed in buildings. Published by the Committee for Electrotechnical Standardization (CLC), this amendment updates the 2006 edition to address modern security needs, including remote access and enhanced communication protocols.

The standard applies to alarm systems utilizing specified or non-specified wired interconnections and wire-free interconnections, including components mounted on the external structure of buildings such as control equipment or warning devices. It excludes requirements for exterior I&HAS and does not cover design, planning, installation, operation, or maintenance processes. EN 50131-1:2006/A3:2020 ensures that I&HAS components perform reliably under classified environmental conditions and operate independently when sharing detection, triggering, control, communication, or power supply resources with other applications.

Key Topics

• System Scope
  EN 50131-1 covers intrusion detection and hold-up alarm functions separately. If an I&HAS lacks a detection function, related requirements do not apply, and vice versa. The standard uses the abbreviation I&HAS to include both Intrusion Alarm Systems (IAS) and Hold-up Alarm Systems (HAS).

• Definitions and Power Supply
  Clarifications are provided for terms like principal prime power source (PPPS), supplementary prime power source, and alternative power source - typically a battery. It outlines minimum durations and recharge requirements for power sources based on system grades.

• Interconnections and Communication
  The standard sets strict requirements for interconnection reliability, ensuring signals or messages are transmitted without delay, modification, substitution, or loss. It requires monitoring of interconnections, with maximum permissible downtime specified for each grade to maintain system integrity. Communication systems supporting remote user access must comply with Annex B.

• Remote Access Security
  Annex B introduces normative requirements for remote access to I&HAS, aiming to protect systems from cyber-security threats. It mandates:

  • Unique identification and validation for remote users.
  • Integrity and confidentiality of communication paths.
  • Logging of failed access attempts.
  • Mechanisms to disable remote access after invalid attempts.
  • Assurance that remote sessions do not interfere with alarm functions.

• Fault Recognition and Event Recording
  The standard prescribes timely identification of faults, including prime power source faults and interconnection failures. Event recording requirements ensure comprehensive logs, including remote access actions, enabling audit and forensic security analysis.

Applications

EN 50131-1:2006/A3:2020 is essential for stakeholders involved in installing and managing security alarm systems in various environments, such as:

• Commercial buildings requiring intrusion and hold-up alarm compliance to safeguard assets and personnel.
• Residential security systems, ensuring robust detection and alarm performance.
• Facility management seeking to integrate alarm systems with other building technologies without performance degradation.
• Alarm system manufacturers and designers, ensuring product compliance with European performance and safety standards.
• Security integrators and service providers implementing remote system access with mandated cybersecurity controls.

This standard supports enhanced safety and reliable alarm operation by prescribing rigorous performance and communication requirements, ensuring intrusion and hold-up alarms function effectively in buildings under diverse environmental conditions.

Related Standards

• EN 50131-3: Specifies requirements for control and indicating equipment (CIE and ACE) within I&HAS.
• EN 50131-5-3: Covers requirements for wireless interconnections in intrusion alarm systems.
• EN 50131-6: Defines power supply categories and related terminology for alarm systems.
• CLC/TS 50131-12:2016: Details methods and requirements for setting and unsetting Intruder Alarm Systems, including the coerciveness principle used for interconnection monitoring.
• EN 50136 Series: Addresses alarm transmission systems and their integration with alarm equipment.
• TS 50131-5-1 (in development): A technical specification focusing on wired interconnection requirements, complementing EN 50131-1’s interconnection clauses.

By aligning with these related standards, EN 50131-1:2006/A3:2020 provides a foundational framework for secure and resilient intrusion and hold-up alarm systems in line with European legislation and industry best practices.
