Hello peter. Thank you for the reply. I have previously installed two alarm systems. One was cabled and the other was wireless. Both came with installation guides of course. Although the system is working fine now it is an old one and if there are any future probs i want to be in the position where i can troubleshoot the board etc. The alarm was put in originally for my parents. They where never given the manual. If they paid for the system they also paid for the installation guide that came with it and where entitled too but never received .
