Hi Guys, We currently have a 10 year old, wired, Nexus 8 intruder alarm. Intending to change it and got a quote from a company for £1000. Anyway...seen this Galaxy G2-20 wireless pack online and it seemed good value for money. Questions: 1. Would it be easy enough to self install/replace the existing one with? 2. I assume (from looking at online manual) that the only wiring that would be involved would be between the keypad, control panel and RF portal? 3. How would I stop the bell box from going off outside if I was to change the panel about? Appreciate the tips guys.
