EN50131 European Standards For Intruder Alarm Systems

The type of Burglar alarm for your home or Business depends on your personal preferences, budget, where your premises are located, the construction and physical layout of the building and what level of protection you need. These considerations will be assessed by our technical survey engineer with yourself at your home/Business during our survey. A key consideration for our recommendation will be how we assess the level of risk to your home and what you would prefer to happen when your system is activated. We install our security systems to the current required BS and EN standards which are-BSEN 50131  & PD6662  

Risk assessment

One of the most significant issues within the new EN standards will be evaluating the risk associated with the premises and determining a grade of system. This is because once the grade of a system is determined it will define the extent of the system, its signaling and tamper security requirements.

Security Grades

One of the most important aspects of the EN 50131 requirements is the concept of a security grade. For each installation the grade of system has to be chosen according to various factors. In the EN the grade is described in terms of the type of intruder and how much effort they would put into a burglary.

Intruders are expected to have little knowledge of the system and may be restricted to a limited range of easily available tools Grade 1 is for a low risk of theft. It applies to a property which is not likely to attract burglars. In the application guide (DC CLC/TS 50131-7), it assumes that a thief is likely to be opportunistic rather than planning a theft and will simply break open a door.

Intruders are expected to have a little more knowledge of the system and use a general range of tools and some specialist equipment. Grade 2 is for a higher risk of theft. Such a property is likely to have something of interest to an experienced thief who is likely to have some knowledge of how your systems work and possibly carry some tools to help him overcome a simple home alarm system. The thief is likely to check the building for easy access through doors, windows and other openings, therefore these are the principle areas of detection.

Intruders are expected to be conversant with the system and have a comprehensive range of tools and portable electronic equipment.. Grade 3 is for a property. which is a reasonably substantial risk, one which, might well contain objects of high value so there is good reason to assume it may be broken into. An intruder is likely to be knowledgeable about intruder alarm-systems and may attempt to overcome the system. The thief is likely to get in by penetrating doors, windows or other openings but can also be expected to gain access by penetration of floors, walls and ceilings so additional protection is required. 

To be used when security takes precedence over all other factors. Intruders are expected to have the resources to plan an intrusion in detail and have a full range of equipment, including the means to substitute vial components in the system.. Grade 4 is for highest-risk properties. Such properties are likely to be targeted by a gang of thieves who will probably have planned the burglary in advance. They will know some techniques for preventing detection or tampering with burglar alarm systems, and therefore, the levels of sophistication need to be that much greater to prevent this happening. 

What Grade of System does my installation need?

This is difficult to say at the moment and opinion on this matter varies from country to country. The view in the UK tends to require grades that are higher than other countries (e.g. a shop in Belgium at grade 2 could be grade 3 in the UK). To a large degree the choice of grade would be guided by insurance companies. A typical view though could be:

Grade 1 would only be of interest in domestic properties (without an insurance requirement for an alarm system).
Grade 2 would be most domestic properties and low risk commercial (e.g. florists)
Grade 3 would be for high-risk domestics and most commercial properties (e.g. Newsagent with cigarette sales)
Grade 4 would be for extremely high-risk domestic and higher risk commercial properties (e.g. bullion stores)

Customer Consultation to provide the right system for you

When dealing with customer requirements, we always ask how you intend to operate your system in terms of users who need to have controlled access and operators who need to manage the system. We will discuss these requirements in a practical sense and then select the most appropriate solution for you. We also always try and offer a base solution which deals with today and can accommodate tomorrow in terms of flexibility and expansion. Our systems offered are usually modular and upgradable via software modules and additional licensing to add features. Our “pay as you grow” designs ensure you do not overspend and only invest when the need arises.

We also respect that when selecting a system your investment needs to be protected and we ALWAYS only use credible equipment manufacturers that have a strong support arrangement in the UK. It is important to remember, when selecting an Access Control System, that this is primarily a software based solution and things can change rapidly with software making manufacturer support is paramount. We also establish the support plans and ongoing software costs which are often overlooked and not budgeted for. Some manufacturers have expensive support models which are not always necessary and we take this into account when advising our customer on system selection.

We are accredited by a wide selection of leading manufacturers to design, install and support Access Control equipment.
