![]() ![]() If your meter doesn't "auto range" make sure that you sweep through the available ranges on your meter.Ĭontacts do fail over time and using this method you can easily track down an offending device by through the process of elimination. It's also good to check that the loop shows a totally "open" circuit when the contact is open. Go back and check to see that the loop resistance has returned to the same value as when you started. Next, open and close a door or window on the loop. Note your initial reading, it should range from a few ohms to no more than 20-30 ohms. Remove the loop from the panel and put your meter on the wires using clip leads, never "hold" the leads on the wires as your body resistance will affect the readings. When testing contacts it is best to test right at the panel. ![]() ![]() Having spent many years in the security industry, and working with GE panels, I would like to offer some tips. I doubt that there is any issue with the NX-8 programming so defaulting the panel won't help you. I would have to agree with BraveSirRobin, ![]()
