READ IT !
this is what we do, we fit systems to a set of regulations, albeit governed by people who really do not have a clue, IMO.
also you could look at BS7671
and a few others that we have copies of
but to be perfectly honest,
if the OP wants an alarm, and does not want to go down the route of having one fitted by a company, so be it,
the way we do things as a installation company are different.
we get asked about DIY systems and we always ask them a few basic questions.
is it a requirement of your insurance company
if so, you will require a certificate of conformity AND a maintenance agreement, (and loads of other paperwork as well)
but if it does not have to be to insurance requirements, well if they want they can fit what they want.
to me its just another blank white or any other colour alarm box outside a building, (sometimes fitted by a sparky, who thinks he can fit alarms).
and if it goes wrong????
look in the mirror and shout at the person who fitted it !!!!
if we fit it, we maintain it, we service, we have a dedicated maintenance team, we have a dedicated install team, and then there is me, who owns the outfit, and also fits, maintains and does the job every day of my life.
so if you want to fit it yourself, GO FOR IT
if you don't, get three quotes, talk to you friends, ask questions.
do not be fobbed off !!!
