As far as the alarm problem, the contractor involved in knowledgeable, owns tools and will get this thing right. They were brought in to solve the problems caused by someone else during the original installation.
I have never known a good contractor not to show up for a test without at least basic tools. What if you have to make an adjustment or put on test gauges? And not knowing what a 3 point test is? I think the 3rd point is AUTO or something like that. I'm not sure, I'm not allowed to touch that stuff.
