Going by NewAge demonstrating such on his somewhat similar AFP-400 in Mini System Test 16 you wire any device to a zone & program its type as “security”, do the same for one or more NACs, & then I guess whenever a zone programmed as a security one goes into alarm that in turn sends the panel into “security alarm” state & sounds whatever NACs are programmed for security (or you instead map a security zone to a security NAC like NewAge did in said test. Could be wrong though as I otherwise know basically nothing about working with Notifier panels).
No, it’s not: it’s nothing like an actual security panel (thus meaning that if you need one you’ll still have to install a separate one. You could still tie the FACP into it if it has a security zone type though (even if doing so probably would end up doing nothing).
The site itself has been defunct for years, but last I checked the files it hosted are still there (somehow/for some reason).
