I have a wiring tech that is great about getting wires from point A to point B and good about making things neat. However, he is completely clueless as far as terminating an alarm panel. While he can do it neat, he does not understand the concepts of NO/NC or how relays work. For example, he spent 2 hours today trying to figure out why a REX button wasnt working and it was because he didnt have one of the lines hooked up to V-.
What is a good training book/website/video, that can help him understand the basics of the technology.
Thanks
