Hi guys.
Just added a standalone expander board ( 8exp I think) to a system we fitted a few years ago.
Existing system already has a plug on expander fitted.
Fitted new expander, confirmed devices, both boards showing up correctly as 1 and 2.
Programed new zones, wiring programmed as Normaly closed all appeared good.
In walk test and when alarm set all new zones showing as closed and not activating when zone is walked?
I am missing something but not sure what.
Thanks all
