Are alarm systems akin to brain-surgery,

They are very simple, or rather the sort of alarm systems one buys
commercially are very simple.

However, "insurance" companies generally specify that such things
can only be done by "professionals" if the "insurance" "policy" is
to be valid.

Therefore you need to be sure why you would want to do this yourself
and what the implications are.
