Ampac Firefinder - Network Break Detected

Hi Guys

Have never worked on this panel before and without having done the training cant get much in the way of support.
From what I can gather the client threw Chubb out due to huge prices but it looks like this is way beyond my technical experience and ability. It is in a large supermarket.

The panel is currently showing the errors below - anyone able to translate?
Does this likely mean there is a break between this panel and a slave / repeater but no other issues - the repeater is in a post office which was closed when I called.

Or is the whole thing f##k#d and I should run away as fast as my little legs can carry me

I've no desire to get involved in anything that will drain my soul but dont want to walk away of its something straight forward.

Cheers
