We haven't had a working house alarm for a good few years since the control panel went "poof" during a power cut. Never got round to replacing it as we were going to extend downstairs anyway and so would have needed new sensors/remove the old ones on doors which were taken down etc
The old one was a wired in system. Part of it is still wires up but as I say the control box doesn't work anymore. It wasn't great - the alarm didnt sound externally, only internally, but we have a fake box on the front of the house.
We need to get a new system really but don't know what to do. Should we get a specialist alarm company in or will that cost £££££? Are wireless systems ok and can you fit them yourself? Saw a Yale wireless system in Aldi the other week and nearly got it but would have had to buy more sensors as there wasn't enough.
Thanks
