Question about Notifier NFS2-640 for maximum current the NACs can handle without an booster/expander panel

[RJARRRPCGP]

I’ve been wondering what the maximum built-in NAC capacity is.

Because in videos, I usually see a booster panel or the like!

Per the manual…

I imagine larger buildings or systems with older signals would need boosters.

Looks pretty good to me, where it should handle a good amount of horn/strobes.
