Hi guys
A big thank you for your advice, it is much appreciated. The main fuse and one small glass fuse had blown, also the battery was completely dead. I ordered a new battery from eBay and replaced fuses and the alarm is working for the first time in eight years! I didn't need to jump any connection as all zones seem to still be working.
I saved loads on calling someone out to repair it so I can spend that money on the family holiday instead ......
A big thank you again for taking the time to share your advice.
Best wishes
