INTRUDER ALARMS PD6662:2010

Published 24/08/2012 11:00

INTRUDER ALARMS PD6662:2010

PD6662:2010 is the Scheme for the application of European Standards for Intrusion and hold-up alarm systems. It is a revision of the PD6662:2004 document, to which British Intruder Alarm systems have been installed. There has been a dual running of the two standards since 31st May 2010 (as the name suggests!) and from 1st June 2012 only PD6662:2010 can be used.

PD6662:2010  serves as a link between the existing British Standard for Intruder and Hold-Up Alarm Systems, BS4737, and the new European Standard, BS EN 50131.

For all new installations (or where a Police URN (Unique Reference Number) has been lost), products installed must comply to PD6662:2010. However we can still install existing products covered by the previous PD6662:2004 standard for the purpose of maintenance of existing installations.

The most notable impact is on the actual security equipment. Products must now meet the new standard requirements. The biggest part of the change is DD243 which has been replaced with BS8243 and includes changes that will be of benefit to installers and end users.

Whilst manufacturers have had to re-manufacture and/or update their products, installers and end users will not be aware of a large number of these changes. Changes to the standard governing “confirmation during entry” are likely to have the biggest impact on end-users.

PD6662:2010/BS8243:2010 standards will have implications in the following key areas:

Confirmation During Entry

The number of detectors off the entry route required to trigger, (after entry and pre-alarm timers have expired), has now been reduced from two to one.

This change means that in order to trigger a confirmed alarm response it will now require activation of only one detector “of the entry route” rather than the 2 detectors previously required. This is a major step forward because once the entry time has expired any intruder deviation from the entry route will quality as a confirmed alarm. This will be particularly useful for “open plan” type shops where the number of rooms off the entry route are limited.

One change that will help installers of grade 3 and 4 systems a great deal relates to a new annex B.1.

Currently under PD6662:2004 if you wanted to add a portable hold up device (wireless Panic Alarm Button) to a grade 3 or 4 system, that installation would be reduced to Grade 2 level as the portable hold up devices that are available from manufacturers only comply to grade 2 requirements. Annex B.1 will be added to PD6662:2010 and will allow grade 2 portable hold up devices to be added to a grade 3 or 4 system without reducing the grade of the installation.

Tamper Signals to the ARC

An additional and separate channel is now required to communicate Tamper to the ARC.

Hold Up Alarms, PA devices and Duress

Grade 2 portable hold up devices (Wireless Panic Alarm Buttons) can now be added to a grade 3 or 4 system without reducing the grade of the installation.

The use of a duress code is now permissible again at Grades 3 and 4, (in agreement with your local police authority).

Arming / Setting the System

The arming procedure is now split into two distinct stages; Stage one initiated inside the premises, Stage two completed outside the premises.

First the system must be commanded to set either with the keypad, the proximity reader or a radio fob.

Second the exit procedure must be terminated. Typically achieved by the closing of the final exit door or pressing a Push-To-Set button.

Disarming / Un-Setting the System

The tag/fob is now called a digital key instead of a PACE,  but the function is the same. When in this mode the panel must be programmed to restrict PIN/Code use. This forces the user to use the tag and will not allow the use of a PIN Code to unset the system, until after an entry timeout alarm has been generated.

Other methods of un-setting require the use of a lock on the final door (that would be connected to the control panel), which will prevent the door being opened unless the alarm has been switched off or confirmation has been disabled (there is a site option to disable confirm on entry if required).

These are excellent ways of protecting the premises as the door being attacked will generate an instant alarm and will doubtlessly be followed by the activation of a PIR, which will confirm the activation and thus the police can be called much faster.

Please don’t hesitate to contact us for further details and advice.
