Elevator and air handling interfaces
The two functions that fail most annuals, and neither one is in NFPA 72.
Elevator recall and duct detector shutdown are fire alarm work, but the requirements come from the elevator code and the mechanical code. This track covers the handoff, so you can explain to an inspector why a device exists and prove on an annual that the interface still does what it is supposed to do.
