Intruder Alarms

Time to learn a bit about intruder alarms.

I send an email to the National Approval Council for Security Systems, NACOSS, that "recognise, inspect and regulate firms who install, maintain and monitor electronic security systems" in the U.K.

Subject: Obfuscation does not provide security!

I have a "Nacoss" installed Intruder alarm (Menvier Security TS700 with Redcare) in my house.
Whilst observing an engineer work on the installation,  I can see several of the circuits do not have the tamper wiring connected - merely a short strap between the screw terminals.
I do not have access to the "comprehensive range of standards and Codes of Practice (COP's) which must be adhered to by NACOSS Recognised Firms. " as stated on I cannot readily check my alarm installation against your standards.
Obfuscation does not provide security!
With interest,

I receive a reply...
Dear Nick
Thank you for your e-mail dated 9 January 2002 timed at 12:32.
British Standards and British Standard Codes of Practice are available from British Standards Institution, 389 Chiswick High Road, London, W4 4AL; telephone 020 8996 9001.  Alternatively you may be able to obtain reference copies through a main library near where you live.  The Standard that you need is most likely to be BS 4737, which comprises a number of Sections and Parts.  We cannot supply these as it would be a breach of the copyright held by BSI.
NACOSS Codes of Practice are available from NACOSS in Maidenhead, price 9 each.  The "technical" Codes of Practice relevant to BS 4737 type systems (which are "wired" systems as opposed to "wire-free") are NACP 10 (Issue 2), NACP 11 (Issue 1) and NACP 14 (Issue 2).
We provide an investigation service for customers who have a complaint about their alarm company.  This service is free.  If you are unhappy about your alarm system we should like to know.  Please contact our Customer-Care Department if you would like us to investigate.
Yours sincerely

Hi Tony
Thanks for your extensive reply.
The offending circuits have been rewired by the alarm company, ADT.

Now do I "get a life" and ignore the alarm system?
