Just so you know.
What are the Security Grades?
A system must meet one of four security grades, depending on the level of risk. These roughly translate as follows:
Grade
G1. Low risk:
Not likely to be enforced in the UK as it covers DIY-style bells-only systems
G2. Medium risk:
This is first level that will be recognised by insurers and covers the majority of domestic & low value commercial premises. Required as a minimum for Police-calling systems
G3. Medium-high risk:
This covers most commercial & industrial premises, as well as high value domestic premises
NB G3 has to have a 5/6 digit EngCde
G4. High risk:
This is for high security applications, & roughly equates to the old BS7042 high security standard
It is the installer’s responsibility to ensure that a system of the correct grade is installed. This must be done via a properly documented Site Survey. Please see En50131-7 for more details on the Site Survey
The advice of the customers’ insurers should be sought if there is any doubt on the grade required
All components will be marked with their security grade

What is this "enforcement" of which you speak?

I was waiting for this, for once in your life do a little searching using Google and you will find all the answers.
I'm not going to spend any more time wasting with you.
Just to help you a little > google.co.uk
Nothing to do with him, you wrote it.
this was my question. It was about what Euro wrote.
I have no idea what's going on inside his twisted mind.
I have no idea what's going on inside his twisted mind.
And your earlier comment was the clue to your question.
If the Insurers ask for g2 or above then diy install isn't acceptable.
so in your opinion, what he meant was "Grade 1 is unlikely to be accepted by UK insurance comapanies if they have asked for Grade 2"
Is that what you think he meant by "enforced?"
It doesn't make sense to me because "enforced" does not mean the same as "accepted."
As you know, many householders are not required by their insurance companies to fit an alarm at all, so they are perfectly free to fit a Grade 1 should they so desire. Especially if they have £150 to spend and not £2,000.

European Intruder Alarm Standards
Four Grades of alarm system exist, based on increasinglevels of resilience against attack by intruders with anticipated levels of knowledge and tools.
Grade 1: Intruders expected to have little knowledge and limited tools. Alarm is suitable for a low risk
Grade 2: Intruders expected to have limited knowledge and some tools. Alarm is suitable for a low to medium risk
Grade 3: Intruders expected to have knowledge and full range of tools. Alarm is suitable for medium to high risk.
Grade 4: Intruders expected to have sophisticated knowledge and tools. Alarm is suitable for a high risk.
Alarm equipment is marked as being suitable for use at a particular grade. Whilst installers will generally use equipment ofthe same grade in each system, it may sometimes be appropriate to mix equipment of differing grades, in which case the official Grade of the whole alarm system is that of the lowest graded piece of equipment used with in it.
There is still little alarm equipment available for grade 4 systems and therefore Alarm installers will use some Grade 3 equipment. However Grade 4 signalling equipment is available and should be installed with all alarm systems in medium to high risk premises e.g.
Jewellers.
The Association of British Insurers (ABI) stopped insurers as a group deciding the grade of alarms because the Office of Fair Trading (OFT) considered it un-competitive with the result that alarm companies decide the alarm grade for the risk. In their quest for business it’s possible for the installing company to recommend a lower grade alarm. Although in theory grade 2 is for low to medium risk and grade 3 for high risk e.g. jewelers, installers quite often recommend Grade 2 equipment.
Please note that in general it is required by insurers that Jewellers install a grade 3 system with Grade 4 signalling. No matter what grade alarm system is installed, Grade 4 signalling is required.
Grading of Detection and control systems
Apart from increasing control panel event memories and levels of recommended detection, the key difference between Grades 2, 3 and 4 is that movement sensors at Grade 3 must be able to detect masking, i.e. something being placed over the sensor lens. At
Grade 4 movement sensors should be able to detect range reduction, i.e. something blocking part of the detectors field of view.
Grading of Signalling Systems
Each signalling Grade has a subset of options showing acceptable combinations of signalling,
e.g. an audible siren and/or a link to an Alarm Receiving Centre (ARC).
Those likely to be used in the UK are:-
Grade 2 - Option X Siren at premises
Grade 2 - Option B Siren + Single link to ARC
Grade 2 - Option C Two links to ARC
Grade 2 - Option D Single link to ARC
Grade 3 - Option B Siren + Single link to ARC
Grade 3 - Option C Two links to ARC
Grade 3 - Option D Single link to ARC
Grade 4 – Option B/C/D Options as Grade 3 above
The performance of the link to the ARC varies between grades.
For example,
Grade 2
Option B signalling must enable an ARC tobe notified of signalling failure with in 25 hours.
Grade 3
Option B must notify the ARC of signalling failure within 5 hours. Grade 4 Option B must notify the ARC of signalling failure within 3 minutes.
Recent changes in the Association of Chief Police Officers (ACPO) policy requirements states that the police will respond to a security system activation either as a result of a confirmed activation through a remotely monitored securitysystem i.e. that two separate signalling systems using different signalling paths must be provided if the police are expected to attend a line cut.
It is therefore required that dual path signalling is installed.
Grading of maintenance
Maintenance requirements are:-
Grade 2 - Option X 1 site visit Per annum
Grade 2&3 - Option B/C/D 2 visits per annum
OR 1 site visit and 1 remote check Grade 4 - Option B/C/D 2 site visits per annum.
Systems that are designed to generate confirmed alarm conditions are further subject to British
Standards Institute document DD 243. These two documents establish minimum standards for alarm systems in buildings (whether commercial or domestic).
They do not however, adequately address all of the features that insurers normally require of an alarm which is intended to protect commercial premises, and it is therefore necessary to give additional specification requirements to alarm installers when purchasing a new system. Please therefore ensure that you pass a copy of the “Risk Management Guide – Alarm Specification” to your intruder alarm company.
Before installing a new Intruder Alarm System please let us see a copy of the proposed specification so we can confirm it meets Insurer’s requirements

I take quite exception to the accusation.
I have NOT added anything to anything. I DO NOT do that sort of thing. How many more times do I have to say that?
