Why can a 90 minute fire door be installed in a 2 hour rated wall?

A 90-minute fire door can be installed in a 2-hour rated wall because it provides a level of protection that is still acceptable within the overall fire-resistance rating of the wall. The wall itself is designed to withstand fire for a longer duration, and the door's rating complements this by offering a significant barrier to fire and smoke for a shorter period. Building codes allow for this combination to ensure safety while also accommodating practical considerations such as accessibility and cost.
