Alarm systems - External perimeter security systems - Part 1: System requirements

This European Standard specifies the requirements for External and Perimeter security systems (EPSS)- installed externally using specific or non-specific wired interconnections or wire-free interconnections. These requirements are not intended to apply to security system, e.g. intruder alarms, visual surveillance system (VSS), access control systems installed in buildings.
This standard specifies performance requirements for installed EPSS but does not include requirements for design, planning, installation, operation or maintenance.
These requirements also apply to EPSS sharing means of detection, triggering, interconnection, control, communication and power supplies with other applications. The operation of a EPSS shall not be adversely influenced by other applications.
Requirements are specified for EPSS components where the relevant environment is classified. This classification describes the environment in which a EPSS component may be expected to operate as designed.
Requirements for two environmental classes are specified for EPSS components. When the requirements of these two environmental classes are inadequate, due to the extreme conditions experienced in certain geographic locations, special national conditions are also specified in Annex A.
Interconnections and products used to combine both an I&HAS and EPSS systems, e.g. control and indicating equipment, should comply to both the IEC 62642 (EN 50131) and EPSS suite of standards. The failure of either system or a fault in either system should not be adversely affect the performance of the other.

Alarmni sistemi - Sistemi za varovanje zunanjih meja - 1. del: Splošne zahteve

Ta evropski standard določa zahteve za sisteme za varovanje zunanjih meja (EPSS), nameščene zunaj zgradb, ki uporabljajo specifične ali nespecifične ožičene ali brezžične medsebojne povezave. Te zahteve se ne uporabljajo za sisteme za varovanje, npr. alarme za javljanje vloma, sisteme za vizualni nadzor (VSS), sisteme nadzora dostopa, vgrajene v stavbah.
Ta standard določa zahteve glede zmogljivosti nameščenih sistemov za varovanje zunanjih meja, vendar ne vključuje zahtev za zasnovo, načrtovanje, namestitev, upravljanje ali vzdrževanje.
Te zahteve veljajo tudi za sisteme za varovanje zunanjih meja, ki si z drugimi aplikacijami delijo sredstva za zaznavanje, sprožanje, medsebojno povezovanje, nadzor, komunikacijo in napajanje. Druge aplikacije ne smejo negativno vplivati na delovanje sistema za varovanje zunanjih meja.
Zahteve so določene za komponente sistema za varovanje zunanjih meja, pri katerih je klasificirano okolje uporabe. Taka klasifikacija opisuje okolje, v katerem komponente sistema za varovanje zunanjih meja delujejo v skladu s svojo zasnovo.
Za komponente sistema za varovanje zunanjih meja so določene zahteve za dva okoljska razreda. Če zahteve teh dveh okoljskih razredov ne zadostujejo zaradi ekstremnih pogojev na nekaterih geografskih območjih, se lahko uporabijo tudi posebni nacionalni pogoji, opredeljeni v dodatku A.
Medsebojne povezave in proizvodi, ki se uporabljajo za združevanje sistemov I&HAS in sistemov za varovanje zunanjih meja, npr. nadzorna in indikatorska oprema, morajo izpolnjevati zahteve standarda IEC 62642 (EN 50131) in zahteve skupine standardov za sisteme za varovanje zunanjih meja. Nedelovanje ali okvara katerega koli sistema ne sme negativno vplivati na delovanje drugega sistema.

Introduction
This Technical Specification applies to External and Perimeter Security Systems.

This Technical Specification is a specification for External and Perimeter Security Systems (EPSS) to

provide detection of intruders in external areas outside enclosed buildings installed in the perimeter outside

buildings. It includes four self protection grades, four environmental classes and four performance

categories.

At the time of writing there is a desire to develop a series of standards for EPSS. This first version of this

technical specification is intended to create a framework to enable development of the other parts of the

series. In particular this will include the application guidelines and the detector component standards. It is

expected that during the development of these other parts enhancements to the system requirements will be

identified.

The purpose of an EPSS is to enhance the security of the supervised premises. To maximize its

effectiveness an EPSS should be integrated with appropriate physical security devices and procedures. This

is particularly important to higher grade EPSS.

This technical specification is intended to assist insurers, intruder alarm companies, customers, the police

and other relevant organisations in achieving a complete and accurate specification of the supervision

required in particular premises, but it does not specify the type of technology, the extent or degree of

detection, nor does it necessarily cover all of the requirements for a particular installation.

All references to the requirements for EPSS refer to basic minimum requirements and the designers of such

installed EPSS should take into account the nature of the premises, the value of the contents, the degree of

risk of intrusion, the threat to personnel and any other factors which may influence the choice of grade and

performance category of an EPSS.

Recommendations for design, planning, operation, installation and maintenance are given in Application

Guidelines CLC/prTS 50661-7 (to be developed).

This technical specification makes allowance for the EPSS designer to vary the design of the system

according to whether the site is usually staffed when the EPSS is in use or continuously staffed and whether

the staff use an internal monitoring station (see definitions) or response is initiated from an alarm receiving

centre.

In the context of this technical specification “external” refers to an area, which is not wholly enclosed inside a

building, within which it is desired to detect intruders. The perimeter is typically a physical boundary to a site.

In some cases the EPSS may include detection devices outside of the physical boundary (e.g. fence) that

are used to provide an early warning of possible intrusion or in combination with perimeter detection devices

to verify a likely crossing of the perimeter.

This technical specification is not intended to be used for testing individual EPSS components. Requirements

for testing individual EPSS components are given in the relevant component standards (to be developed).

CLC/TS 50661-1:2017 (E)
1 Scope

This Technical Specification specifies the requirements for security systems to provide detection of intruders

in external areas outside enclosed buildings.

For enclosed buildings EN 50131-1 should be applied. CLC/TS 50661-1 may be used for unenclosed

buildings such as roofed storage areas where an intruder and hold-up alarm system is not suitable.

This Technical Specification specifies performance requirements for installed EPSS but does not include

requirements for designing, planning, installation, operation or maintenance.

These requirements also apply to EPSS sharing means of detection, interconnection, control, communication

and power supplies with other applications.

This Technical Specification references requirements for system components according to the environment

where they are expected to operate as designed. These environmental conditions are classified.

This Technical Specification does not deal with requirements for compliance with EC regulatory Directives,

such as the RED Directive, EMC Directive, Low Voltage Directive, etc. except that it specifies the equipment

operating conditions for EMC susceptibility testing as required by EN 50130-4.

4 System Structure
4.1 General

The EPSS may be formed from one physical unit or its functionality may be provided by a combination of

multiple devices.

An EPSS may be operated in conjunction with other electronic security and alarm systems such as I&HAS,

VSS and ACS. Further interfaces to other security systems are permitted providing these do not interfere

with the mandatory requirements of this technical specification.
Figure 1 shows a typical system architecture of an EPSS and associated systems.
Figure 1 — Typical infrastructure of an EPSS

NOTE For Figure 1, the terms controller, power supply and detector are defined (see 3.1). The abbreviations are

explained in 3.2.
4.2 EPSS central functions

NOTE The mandatory functions required by this technical specification related to the receiving of signals and

messages from the user, the detectors and other connected systems (e.g. I&HAS, VSS, ACS) and processing them on

the basis of the system state and the configuration in the data storage are considered as the EPSS central functions.

---------------------- Page: 15 ----------------------
SIST-TS CLC/TS 50661-1:2017
CLC/TS 50661-1:2017 (E)

The EPSS central functions may be provided by a single device or divided amongst multiple components.

The EPSS central functions may be provided within a component that provides other (non-central)

functionality, e.g. detectors.

The EPSS central functions shall generate signals and data for the provision of notification and indications,

other controlled devices (e.g. lighting) and actuators and, as appropriate, outputs to other systems.

4.3 Transceiver

EPSS may inform an Alarm Receiving Centre (ARC, MARC, RVRC) and/or other persons that alarm, fault or

tamper conditions are present. In the case of communication to an ARC the functionality for communicating

information from the EPSS shall be provided by a Supervised Premises Transceiver (SPT) that forms part of

an Alarm Transmission System (ATS). Communication to other persons, not via an ARC, may use other

forms of transceiver. See Clause 8.
NOTE Requirements for ATS are given in the EN 50136 series of standards.
4.4 User interface
