Help with nfs 640

So how exactly do you make NAC 2 non silenceable

I believe in Verifier Tools there is a checkable box for silenceable or non.

Question… where do i get the cable and the software for it? Because when I got this panel i just thought you could do everything from the menu. Idk im used to the ms 2 that has dip switches and panels like the NFS-640 are new to me.

The cable is probably available on the internet. As far as the software, generally you would need to be a Notifier dealer and take a training class although you may be able to find a pirate copy on the net.
