What new standards? • PD6662:2010 – Replaces PD6662:2004 – Incorporates:• The latest versions of EN50131 where published • Older BS4737 requirements if an EN50131 has not yet been created for those items or systems
• BS8243:2010 – Replaces DD243 and DD263 – Incorporates most of the ACPO requirements
• DD263:2010 – Replaces older versions, much of which is now incorporated into PD6662:2010 and BS8243:2010

When is PD6662:2010 applicable? • PD6662:2010 came into force on 1st May 2010 but with a 24 month dualrunning provision for installers to comply • Installers must switch totally to PD6662:2010 on 1st May 2012 • During the dual-running period an installer can choose to install and commission to either standard – But he cannot mix both standards in the same installation – E.g. he cannot install the panel to PD6662:2010 and the sensors to PD6662:2004
• If you are designing a system that will be commissioned after 1st May 2012 it must comply with the new standards or it cannot receive an NSI certificate or police attendance

PD6662:2010 – the changes • This version takes into account the publication of a number of new, revised or amended EN standards. • It also adds some new standards and documents published by the British Standards Institute that add or vary the requirements for alarm confirmation, commissioning, maintenance and false alarm management • The standard’s description has been changed from ‘intruder’ to ‘intrusion’ so that it now matches the title of EN50131-1 and removes any possible misinterpretation! • Reference is now made to BS EN 50131-1:2006 instead of prEN50131-1:2004

Changes • System Standards have been updated to include all the latest versions, e.g. prEN50131-1:2004 replaced by BS EN 501311:2006 + Appendix A1:2009 • Component standards have had similar treatment where :2008 or :2009 versions have replaced all the previous DD CLC/TS50131-2 -xx:2004 requirements • You must ensure when specifying sensors, sounders etc that they conform to this later version, – You cannot continue to use :2004 sensors in a :2010 installation unless there is no later revision for that item
• The following new abbreviations have been added:– ATS = alarm transmission system – HAS = hold-up alarm system – SPT = supervised Premises transceiver 5 Document control number

BS8243:2010 • The full title is:– BS8243:2010 Installation and configuration of intruder and holdup alarm systems designed to generate confirmed alarm conditions – Code of practice.
• The gist of this is to cater for new technology advances in the way confirmation of both intrusion and HAS activations can be improved • BS8243:2010 replaces DD243:2004 • Effective NOW! • Except for new systems still conforming to PD6662:2004 – DD243 can still be applied to such systems installed up to 30th May 2012
• All systems installed to PD6662:2010 must use BS8243:2010

BS8243:2010 vs DD243:2004 • Main change is the separation of the confirmation requirements for intrusion (IAS) and hold up alarms (HAS) • Confirmation for HAS is subject to the conditions of the ACPO policy ‘ACPO 10 point plan’ and not in all cases • BS8243:2010 now includes specific design objectives for HAS and includes technology requirements • For IAS, new information about the initiation and completion of system setting have been added • A new recommendation takes into account the situation where detection of the opening of an entry door is not possible – The standard shows two acceptable alternatives

DD263:2010 • DD263:2010 is defined as :– Intruder and Hold-up Alarm Systems – Commissioning, maintenance and Remote Support – Code of Practice
• Not just for use with PD 6662: 2010 can also be used with older • systems including BS 4737 and BS 7042. If you can still find any compatible equipment! • Can be used now with any scheme • Must be used on all PD 6662: 2010 installations

How to Initialise Remote Access • Methods: a) Automatic - Initiated automatically by the I&HAS e.g. scheduled timer b) Manual - on-site - Initiated on site by a user or an installer c) Manual - remote - initiated by a secure computer with restrictions above grade 2 - (G3) I&HAS must identify computer by IP address or fixed landline phone number - (G3 or G4) using encryption techniques (from EN 50136) - (G3) user or installer on site accepts incoming connection d) Manual - remote with PSTN or ISDN ring-back - secure computer calls I&HAS then drops connection and I&HAS calls back

Remote System Checks • Remote system check: electronic check of I&HAS status as part of preventative maintenance • Remote support: carry out some or all CIE functions remotely • Both require the use of a “secure computer” :- which is one with security measures to prevent access the same as the access level restrictions in EN 50131-1 - The secure computer must be within the premises of the alarm company or an ARC
• Remote access should comply with EN 50131-3 Annex C (primarily for manufacturers). This says which bits of EN50131-3 apply to the secure computer 11 Document control number
