Hi: I am a DIY-er, and have a panel that has been showing some weird behavior lately. It's been showing a Low Batt indication, while showing zones 30-33. This is after the system has been armed, away for a few mins. I have mostly wireless sensors, running roughly 3-15, and none of my zone #'s go into the 30's. I looked in my manual and it looks like these are zones for time/date, and other various functions. I thought it might be the backup battery up, so I replaced that, but it still shows the error condition. Could it be a bad power supply? Any suggestions are greatly appreciated. Thanks in advance!
