Alarm systems - Intrusion systems - Part 5-1: Interconnections - Requirements for wired Interconnection for I&HAS equipments located in supervised premises

This document applies to interconnections between intrusion and hold-up alarm system components using specific or non-specific wired interconnections (e.g. between SPT and CIE). The interconnected components are located within the supervised premises, or mounted on the outside of the supervised premises (e.g. external warning devices).
This document does not apply to interconnections between components located within the same enclosure, or to interconnections between parts of an I&HAS component if covered by the relevant product standard. This document does not define the physical requirements of the interconnection media.
This document is expected to be used in conjunction with the other parts of the EN 50131 series that define the functional requirements of the equipment regardless of the interconnection technique used.
Where monitoring of the functionality of the interconnections is undertaken by an interconnected component, this is defined in the relevant product standard in the EN 50131 series. If a component standard indicates that an interconnection will be monitored, then this document determines the monitored conditions applicable to the interconnection.
NOTE 1   For example, if there is no requirement in a detector standard to monitor a remote indication of detection input, this document does not apply to that particular interconnection.
Requirements for the monitoring of the functionality of power connections between I&HAS components are defined in the relevant product standard and are not included within this document.
This document defines the terms used in the field of intrusion and hold-up alarm equipment using such interconnections and includes the requirements relevant to the equipment interfaces.
Wired interconnection media can include metallic single stranded insulated cable, metallic multi-stranded insulated cable, and fibre optic cable. These cables can comprise single or multiple cores.
NOTE 2    Interconnections using RF techniques (i.e. wire free interconnections) are dealt with by EN 50131 5 3.

Introduction

The wired interconnection forms the link between I&HAS components to transfer information and, where

appropriate, power, as required for reliable system operation.

The transfer of information may be by means of signals or messages as appropriate to the I&HAS and its

security grade.

Selection of the type of interconnection media and its installation can affect the reliability and grade of the

I&HAS.

Interconnections may be dedicated to a single I&HAS (specific interconnections) or shared with one or more

alarm or other systems (non-specific interconnections). The relative priorities of the different systems are

determined according to EN 50398-1.

1 Scope

This document applies to interconnections between intrusion and hold-up alarm system components using

specific or non-specific wired interconnections (e.g. between SPT and CIE). The interconnected components

are located within the supervised premises, or mounted on the outside of the supervised premises (e.g. external

warning devices).

This document does not apply to interconnections between components located within the same enclosure, or

to interconnections between parts of an I&HAS component if covered by the relevant product standard. This

document does not define the physical requirements of the interconnection media.

This document is expected to be used in conjunction with the other parts of the EN 50131 series that define the

functional requirements of the equipment regardless of the interconnection technique used.

Where monitoring of the functionality of the interconnections is undertaken by an interconnected component,

this is defined in the relevant product standard in the EN 50131 series. If a component standard indicates that

an interconnection will be monitored, then this document determines the monitored conditions applicable to the

interconnection.

NOTE 1 For example, if there is no requirement in a detector standard to monitor a remote indication of detection input,

this document does not apply to that particular interconnection.

Requirements for the monitoring of the functionality of power connections between I&HAS components are

defined in the relevant product standard and are not included within this document.

This document defines the terms used in the field of intrusion and hold-up alarm equipment using such

interconnections and includes the requirements relevant to the equipment interfaces.

Wired interconnection media can include metallic single stranded insulated cable, metallic multi-stranded

insulated cable, and fibre optic cable. These cables can comprise single or multiple cores.

NOTE 2 Interconnections using RF techniques (i.e. wire free interconnections) are dealt with by EN 50131-5-3.

4.1 General
4.1.1 Introduction

Wired interconnections shall be suitable for the purpose and designed to provide a reliable means of

SIST-TS CLC/TS 50131-5-1:2021
CLC/TS 50131-5-1:2021 (E)
communication and/or power between I&HAS components.

A wired interconnection shall be available when needed to convey signals or messages and/or power between

components, or between physically separate (i.e. housed in different enclosures) parts of a single component

(e.g. CIE) during all states of the system: unset, setting, set, un-setting.

Selection of the type of interconnection media and its installation can affect the reliability and security grade of

the I&HAS and should be made in accordance with the I&HAS components manufacturers’ specifications and

the principles contained in TS50131-7.

NOTE For clarity, Annex A contains a summary of interconnection requirements for each interconnection type.

4.1.2 Interconnection Integrity
4.1.2.1 General

The following requirements relate to the physical integrity of the interconnection between the I&HAS

components.
4.1.2.2 Signal based interconnections

Signal-based interconnections shall be monitored such that any of the conditions identified in Table 1 will be

detected and processed within 10 s of the condition occurring.

In Table 1, Setting is treated as a system in the Unset state, and Unsetting is treated as a system in the Set

state

Optional during UNSET, but not during SETTING, for components installed in systems meeting the

requirements of EN 50131–1 “Monitoring of interconnections (Coerciveness Principle)”

4.1.2.3 Message based interconnections

Message-based interconnections shall be monitored such that any of the conditions identified in Table 2 that

result in loss of communication will be detected within 10 s of the condition occurring.

Compliance may be demonstrated either by electrical tests or by the monitoring of the receipt of messages

provided that the 10 s requirement is met.
