Alarm systems - Intrusion and hold-up systems - Part 3: Control and indicating equipment EN 50131-3:2026

Publication date:   Apr 16, 2026

Scope

This document specifies the requirements, performance criteria and testing procedures for control and indicating equipment (CIE) intended for use in intrusion and hold-up alarm systems (I&HAS) installed in buildings. This document also applies to CIE to be used in IAS or HAS.
The CIE can incorporate processing functions of other I&HAS components or its processing requirements can be distributed among such components.
This document specifies the requirements for CIE installed in buildings using specific or non-specific wired interconnections or wire-free interconnections. These requirements also apply to basic DCC which can be installed outside of the supervised premises and mounted in indoor or outdoor environments.
Where CIE shares means of detection, interconnection, control, communication, processing and/or power supplies with other applications, these requirements apply to I&HAS functions only.
This document specifies performance requirements for CIE at each of the four security grades identified in EN 50131-1. Requirements are also specified for four environmental classes covering applications for indoor and outdoor locations.
This document includes mandatory functions for all CIE for the appropriate security grade, as well as optional functions that can additionally be provided.
This document does not cover requirements for compliance with EU regulatory Directives, such as the EMC Directive, Low Voltage Directive, etc. except in that it specifies the equipment operating conditions for EMC susceptibility testing as required by EN 50130-4.
NOTE 1 In this document reference to the term "I&HAS" is used throughout, except where there is specific need to differentiate between the IAS and HAS portions of a system. The term is intended to include IAS and HAS when such systems are installed separately.
NOTE 2 For products which integrate functions from, and which the manufacturer is claiming compliance to, several EN 50131 standards, the requirements of this document apply as well as any additional requirements from other relevant EN 50131 standards (e.g. a CIE with integral Warning Device is expected to meet the requirements of EN 50131-3 and EN 50131-4).
