Got Paradox Alarm installed for my double storey semi-d somewhere in 2006. Till now it is still working fine. I thankfully haven't experienced break in. I hope I never do. I received 3 quotations during renovation and I chose the most expensive/ reputable one. The zones were properly planned and the cables are brand new. No looping no joining cables. The company is EE Automation 016 - 639 2272.
