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. However, it is essential that the installation adheres to specific guidelines and standards to maintain overall fire safety.
