Can you T-tap in a fire alarm system for addressable devices? Code references please.

All map net systems per UL listing can be T t_-Taped , Even the horns and lights if your using the approved type.

You can t-tap a Class 'B' addressable SLC loop if the project specifications permit. No code violation.
A class 'A' loop cannot be t-taped.
