This is the 2nd time this has happened. Now out of warantee. After a 1-2 second power blink off/on from the power company, the SC1200 console shows either Tamper 1 or Trouble zone 17. I don't have a zone 17 installed. If I try to arm the unit. It won't let me clear the fault so I can't arm it. Yes, I have good backup batteries in the unit. When I try to enter my pin, I get the error message. Also tried default 0000 pin and get error. I have also tried the 7,9,on,clear reset with no help trying to get into the "test" mode. The unit seems to be in some locked up state. My only solution seems to be what I did before - unplug the wall wart power unit, remove batteries, short battery contacts to clear the memory, let it sit for several hours and do a fresh reinstall of all my (16) zones and remotes. A real PITA.
A power blink should not cause this to happen. The security system should be immune to this. I upgraded to the SC1200 from the DS7000 to get better control & features. Now this problem. Anyone have any ideas? I will call X10 but don't expect any help.
