A change in Intruder and Hold Up Alarm standards

All Intruder and Hold Up Alarm* systems installed within the European Union must meet fundamental standards in order to be accepted by insurance companies and to be allowed to summon a police response. The European standard applicable to Intruder and Hold Up Alarms is the EN50131 series. Each country in Europe often has its own individual requirements which alarm systems must also comply with. In the UK these additional standards are represented by the PD6662 and BS8243 standards. PD6662:2010 PD6662 is the scheme which enables Intruder and Hold Up Alarm systems to be installed and maintained in accordance with published British and European Standards. PD6662 introduces some UK specific changes to the EN50131 series. A new version of this standard was formulated in 2010 and the UK security industry agreed to make it mandatory in June 2012. The changes in standard affect the initial risk assessment and system design; the arming and disarming methods and tampers in intruder and hold up alarms. These changes will now be adopted by Grantfen Fire & Security in the design and specification of all new alarm systems and alarm upgrades.

The BS8243:2010 standard refers to the system requirements and the process relating to when the Police are called to respond to an Intruder or Hold Up Alarm. As of 1st April 2012 ACPO (Association of Chief Police Officers) requires applications for Hold Up Alarms to have a separate URN (Unique Reference Number) in addition to the usual Intruder Alarm URN. A URN is how the police identify that the system is compliant and therefore suitable to obtain a police response. Depending on the specific Police force requirements, Hold Up alarms are required to be confirmed before the Police will respond; this can be via sequential, audio or visual confirmation and telephone confirmation (also known as Intervention or call back). A sequential confirmation can be achieved by either the activation of two separate dual action devices or a single device with multiple buttons.

From the 1st June 2012, all new Intruder and Hold Up Alarms will be designed and installed to the EN50131:2006 standard in accordance with PD6662:2010 and BS8243 for police calling systems.

Why do these standards affect me?
These standards have been written and designed to satisfy APCO (Association of Chief Police Officers) and insurers that Intruder and Hold Up Alarms have been designed and installed by a certified company. Any new Intruder and Hold Up system should be installed to comply with PD6662:2010 and BS8243:2010 (if the system is Police calling). Systems which now lose Police Response will only be reinstated if they comply with the new changes. In some cases this will mean a control panel upgrade.

Should I upgrade my existing system to comply with PD6662?
If your system currently complies with legacy British or European standards and operates effectively then there is no need to make any changes. If you need to make a major upgrade to your old system then the upgraded system will need to comply with PD6662:2010. This may be a requirement of your insurer.


would say with confidence that Grantfen are one of the best specialist sub-contractors I have worked with. They have completed three projects for BBES (but have completed several more for other personnel) under my control which where.
