DELInstallations said:Using Cat X cable brings the M1's total bus length down to 2K OAL. To start eliminating components, you can always move them to the panel and connect everything there. No issues means the problem is the media and not firmware/programming.
I would start by disconnecting the buried cable and then restrip and, assuming it's flooded cable, remove the grease and meter everything to ground. I don't know of the cable construction, but usually it's a poly outer, then a foil/flooded and then the inner conductors laid within the gel. Very easy to nick and cause a bridge to ground, especially with burial.
Let's get back to basics....what is connected to the bus and where (I'm being a little lazy and don't want to go re-read and wade through posts) You state the bus goes from the house to the garage and only to a 212, nothing else? Jumper removed at the panel?
I doubt the bus within the house is the issue, but redoing connections is usually an easy and logical step.
I just got disgusted and reset the control using global 45 again. I opened a new account and the only thing connected is the house keypad via dbh and four wired zones.
The reasn that did this is because the system was acting unpredictable. When I tried to remove the wireless by unplugging it from the dbh and re-enrolling the devices the system reported that input expander 2 is missing. There should be no input expander 2 as far as I know.
I will try to connect the garage p212s now and see how it goes.
