today we are going to show you how to replace your distant door contacts if you managed to damage it somehow for this we're going to show you this is a grade one contact as we know it today this is what would normally be fitted on a domestic alarm system usually on a PVC door or an old wooden door where it's been awkward if it's lost contact generally these grade one style contacts are mostly the same size and what we're looking at inside here is the two silver terminals for the contact and the three brass screws here are just four joint in the cables together what we're going to do is we're going to rewire this contacts using four wires now there's no set color codes for installers to use so I'm just going to choose four for the purpose of demonstration which is going to be red and black and blue and yellow I'm gonna strip each of the cores back that I want to use about a centimeter or
