My house has a Vista 10 SE alarm system. The board was locked, so I ordered a new board off ebay and installed it.
I was able to set both the installer and master code.s After the system comes up the display shows "05 CHECK", then after a while the alarm goes off. I don't have a sensor wired to zone 5 and I am unable to bypass it (I can bypass other sensors).
Is it possible that zone 5 is wanting a fire detector on zone 5? A motion sensor was wired to zone 5. I disconnected that to make sure it was not the problem.
Does that sound like the problem? Any ideas on how to fix it?
thanks chad
