To help ensure that alarms are designed, installed and maintained reliably, most UK alarm suppliers and installers adhere to a series of British Standards or Codes of Practice (CoP).
In 2004 the process of withdrawing some long established British Standards/CoP began, their place being taken by new European Standards for Intruder and Hold up Alarm Systems - usually referred to as the ‘Euro Standards'.
The Euro Standards only apply to new systems. Existing systems remain subject to the British Standards or CoP applying at the time of their installation; but exceptionally may need to comply with the Euro Standards if they require such extensive re-design or equipment replacement that they effectively become a new system.
This Hardfacts only provides general guidance on the Euro Standards - more detailed guidance documents are available from The RISC Authority, the UK insurers' technical advice body and other organisations.
From 1st March 2004 documents entirely or partly withdrawn include:
The Euro Standards, as termed, actually comprise a suite of document published under two document numbers, as shown:-
Means of Introduction
Because some parts of the full suite of Euro Standards are not yet published, and the Euro Standards do not cover some issues that alarms may be required to meet in the UK to satisfy the police or insurers, a UK enabling standard was prepared. This is called PD6662 - Scheme for the application of European Standards for Intruder and Hold up Alarm Systems''.
Grading and the European Standards
The key feature of the Euro Standards is the system of grading.
Four ‘Grades' of alarm system exist, based on increasing levels of resilience against attack by intruders with anticipated levels of alarm knowledge and tools as shown below:
Grade Intruders expected to have:
1 Little knowledge and limited tools
2 Limited knowledge and some tools
3 Knowledge and full range of tools
4 Sophisticated knowledge and tools
In reality, Grade 1 is a low (below the old BS 4737 Standard) level of system not acceptable for police response and Grade 4 equipment isn’t generally available, so the effective choice is between Grade 2 and Grade 3.
In a similar vein, any connected ATS has to meet increasing levels of performance based on the Grade of alarm system they are connected to. Although ATS do not technically have an official Grade designation, in common parlance the alarm industry does refer to the various types of ATS and their performance as ‘grades’ of signalling.
Who Decides the Grade of Alarm?
Whilst an interested customer will naturally take an interest in/help determine the type of alarm system they wish to buy, the main role of determining graded performance will usually lie with two other parties.
Alarm Companies (Installers)
Installers are required to carry out a formal assessment of the theft risk to determine a suitable Grade of alarm and a type/grade of ATS. To do so they will consider the items at risk, existing security arrangements and any previous thefts, etc. Before they proceed they will (ideally) encourage a customer to seek any interested insurer's approval.
Depending on the risk exposure, insurers may require an intruder alarm before providing certain insurance covers, e.g. theft. As the Grade of an alarm cannot be readily changed after installation, it makes sense to check a proposed alarm with any interested insurer before proceeding. When it comes to any ATS, it's 'grade' can often be restrospectively changed, but it may involve extra cost that is better avoided by meeting an insurer's requirement at the outset.
Insurers may respond to a request to approve an alarm by visiting the premises, making a decision based on information already held by them, or by agreeing with an installer's risk assessment.
As a general guide the following reflects insurers likely stance on Euro Standards systems and ATS:
Detection and Control System
* One ATS certification scheme that many insurers recognise - and the only one that Aviva routinely recommends - is that operated by Loss Prevention Certification Board (LPCB) and known as LPS 1277 3.0. This scheme not only tests ATS to the baseline Euro Standards, but additionally deals with some known gaps/deficiencies of particular interest to UK insurers. As a result ATS products certified under this scheme are described as having ‘Enhanced’ ATS values.)
Other Features of the European Standards
Whilst the Euro Standards contain a lot of complex detail/requirements, the following are its key other features:
With regard to the four Grades of alarm system mentioned, equipment suppliers will mark each piece of alarm equipment as being suitable for use at a particular Grade, and also its Environmental Class - its suitability for use in dry/wet &/or hot/cold conditions.
Installers will generally use equipment of the same Grade across a system, but mixing equipment of differing Grades may sometimes be appropriate. In such cases the official Grade of the alarm system will follow that of the lowest graded piece of equipment used within it.
Detection and Control System - Grading
Apart from increasing event memories, length of battery back up power and levels of recommended detection, the key difference between Grades 2, 3 and 4 relates to movement sensors, and is this:
Each Grade of system has a subset of ‘Notification Options’ showing acceptable combinations of alarm signalling, e.g. an audible site siren (Warning Device) and/or links to an Alarm Receiving Centre (ARC) via an ATS. Those most likely to be used in the UK are:
‘grade’ Option Signalling Type
2 X Siren at premises
B Siren + single link to ARC
C Two links to ARC
3 & 4 B & C As ‘grade’ 2 above
The performance of the link to the ARC varies between the ‘grades’, the most notable difference being in the times taken for any lost signalling link (path) to be noted and reported to the ARC. For example:-
In a Dual Path (Option C) ATS (where two signalling paths are installed, one landline based one mobile network based), the primary path will have a reporting time as above, and the secondary path, when not in use, will have a lower performance - which insurers will expect to ‘step up’ to match that of the primary path once it is in use.
Maintenance requirements are:-
Grade Option Maintenance
2 X 1 site visit per annum
2 & 3 BC 2 site visits per annum OR
1 site and 1 remote check
4 BC 2 site visits per annum
The availability of police response is governed by police Security System Policy (SSP). The SSP requires new alarms to comply with the Euro Standards. See ‘Hardfacts' 3008: Police Response to Security Systems for more information.
