kidde vega keyswitch isolation

Hi all, in need of a little help.
It’s been a long time since writing cause and effect on a kidde Vega.
Now I’m in front of one and can’t remember if it is possible, or how to set up an xp95 I/O input to isolate an output group of output units...
Any help would be greatly appreciated as kidde tech support have long since gone home.
Thanks.
