true, in case other diyers read this, op original post makes no sense leading up to this , but it is possible to blag your way through it , battery afters years is still needs to be changed having it connected without a load test and so on gives no guarantee, ignore rs232 comment and follow the manual , and default zones all need to be programmed, none of it is an oddity realistically, the fire zones would have been either setup by the op in error or its a used pcb or they are defaulted to those attributes on those zones from factory even tho unlikely, so watch where you buy it as op forgot to mention , from new make sure you default it anyway as a diyer that is..
atleast it might be working now so all good
