Hope someone can help.....
We have a Friedland SA5 6 zone wireless alarm system that I installed approx
five years ago, and have maintained since. This unit is very similar to Yale
wireless alarms so one or othe is probably a rebadged version.
Anyway we've recently changed house building & contents insurer. Our new
insurer is insisting that there is a maintenance contract in place. I've
been phoning round & consistently failing to find a company who will take on
a diy installed system.

Are there security companies out there who will maintain diy installed
alarms? or will I have to give up & get an equivalent approved system
installed at vast unnecessary expense.
Location is Ealing, West London.
