Hi everyone,

apologies if there is already a thread on this but i tried searching.

i'm a student at university doing a project on home security. i have been a bit stuck on the standards as there is a lot to filter through to get to the vital information and even then, i don't really understand what is necessary.

so far i have gathered that

- intruder alarms have to comply to EN50131 & DD243 - which is a code of practice?

- thief resistant locks have BS3621, BS8621, BS10621. - they are seem the same to me.

can anyone simplify the important requirements of these standards or is it just a matter of reading through the material?

many thanks,

Intruder alarms bs en 50131, 50136, bs 8243, pd 6662 and dd263

But you then have all the component standards ontop

locks I don't know

Intruder alarms bs ....

BS 4737 FYI

True still parts of that in use

thanks for your prompt replies.

wow. with all these standards, how do designers ensure they meet every requirement? BS50131 in itself has 8 parts with each document at over 30+ pages long.

these limitations can only hinder technological advances surely?

It shouldnt hinder no. Could say the same about cars, would you want a car that didnt meet a single standard?

Its not quite as hard as it seems, the panel does a lot of it already, another large lump is common sense, we just need to be sure that we put detectors in the right place. And at the end of it all we audit ourselves to check that we have complied. Compared to flipping burgers at Mc Donalds its a doddle lol

As above for the IAS side.

Lock side deals with more anti pick/bump. Also multipoint and types of key/key key/knob and fire standards (Locks available and able to be secure at the same time as being easy to use for egress.

Lots of reading, and costs. Join BSI and get a reduced rate

true. i imagine most of the standard is about fault prevention and tamper detection as opposed to positioning of the system?

haha! so the panel is where all the electrics are housed? i'm still trying to wise up on the basic circuitry.

another question, can someone tell me the differences between microwave detectors and ultrasonic detectors?

thanks for the information.

i have actually got access to all the standards online through the university database. but its just filtering out everything and understanding the terms used.

A fair bit of freq. same principe but different frequencies
