compustar brains

Im looking in to getting a new compustar alarm system i currently have the CM3000 and i have not been to happy with it as it sometimes stops working and i have unplug the brain for a few hours sometimes days to get it to reset. I was curious do all compustar brains have the same wiring connectors? would i be able to plug in a new brain with out having to remove all the old wiring?

They are not all exactly the same, I am also not sure I would want to plug a new brain into wiring of a system with problems, your problem may be the wiring. 94
