Howdy!
This panel is one of the rare ones that doesn’t actually check whether the addressable device is the matching FCI brand, so if you have, say, a Notifier NBG-12LX and a Fire-Lite SD-335A along with your standard FCI MS-7 and ASD-PL2F (pull stations and smoke detectors respectively), they should all work fine on the 7100. That’s actually one of the reasons I want that panel so bad.
What devices did you have in mind that you wanted to use with this panel?
