Morphology

fire + door

The meaning is compositionally built from 'fire' (burning) + 'door' (a barrier): a door associated with fire protection, i.e. one designed to resist or contain fire. This noun–noun modifier pattern is regular and cross-linguistically common, so a B1 learner who knows both constituents will readily infer the intended function.

Etymology

Fire door is very literal: it is a door made to hold back fire and smoke from moving from one room to another. That's why a fire door today means a special door that 'prevents the spread of fire' and helps keep people safe.
