From what I understand about the requirement side of things if the system is voluntary it doesn’t need to meet any code requirements. If it is required, then it must meet the UUKL & 864 requirements where everything is supervised, on emergency power, etc. The FACP may need to be cross listed with the smoke control panel depending on the AHJ.
I’ve done quite a bit of those back in the mid 90’s down in South Florida. Basically what Chris said about monitoring for integrity. You may also need to post trouble messages if a switch on the smoke control panel is off normal (not in auto) when the system is normal.
Also keep in mind that some of those graphic panels can be pretty expensive. Kirkland is very expensive from what I recall and kind of a pain to mount the faceplate to the enclosure. Light Engineered Displays always seemed to work well for me when I worked for Siemens. They will custom make the faceplate to fit whatever you need it to fit and they were about 1/2 the price of Kirkland.
