Simplex 4003 no message help

I’m working on a 4003
the panel active now thanks to a prior post about the 0v reference
now it only woops but does not play the message.
I’ve triple checked the settings on sw2 and attempted a few different configurations but cannot get the message to play
the 4003 is triggered from a NAC off the host panel.
I’m on site now but have a few days to figure it out
thanks in advance all

host panel is a simplex 4100
