Access Control System Standards

This European Standard BS EN 50133-7:1999 has been established as a source of information for the managers and purchasers of access control systems as a guideline for the establishment of tenders and for the installers and the maintainers.

This European Standard mainly covers the people flow to, or in, Security Controlled areas and may also be used to control the flow of other things such as cars.

This standard provides guidelines for the application of an automated access control system and components in and around buildings based upon the EN50133 series of standards. It covers system design, installation, handover, operation and maintenance of access control systems.

The guidelines are intended for access control systems for use in security applications.  They cover systems ranging from a simple single access point up to complex multiple access point systems.

Access control can be an important part of an overall electronic security system, it enhances the security of employees, buildings and assets, it should integrate well with other in-house security measures and produce a reduction in the overall cost of managing security, if designed and installed well.

Good design will result in the selection of the right equipment, much of this will be dictated by the Grade of the system. For example - Tokens (what you have), Swipe cards, Contact cards or Tags, Passive proximity, Active proximity, RFID or PINs, (what you know) and Biometric (what you are) singularly or for Grade 3 systems, a token and a PIN would be needed or a single biometric reading.

Access control systems are graded in a similar fashion to IDS (intruder detection systems),


There are four grades:


Grade 1 (Low Risk)

A standalone lock (code, PIN or token), or off-line system, controlled in a public area for low risk situations.

Grade 2 (Low to medium risk)

An on-line system utilising tokens or PINs to prevent access to the premises. Events are received in real-time on the monitoring software.

Grade 3 (Medium to high risk)

An on-line system using two factor authentication or single-factor biometric to prevent access to the premises. Events are received in real-time on the monitoring software.

Grade 4 (High risk)

An on-line system using two (or more) factor authentication, one of which should be biometric or human image verification to prevent access to the premises. Events are received in real-time on the monitoring software. When using biometrics, careful selection of the quality should be carried out to reduce the FAR (false alarm rate).

The grade applied to each point may vary by time, increasing for example from card only during office hours to card and PIN outside hours. Grades are applicable to the point of entry and not the whole system, unlike Intruder Alarm Systems.
