You have an existing single door swinging into a stairwell, with a 90-minute fire rating. The door has fire exit hardware with non-locking trim on the stair side, and the owner wants to add access control to prevent unauthorized people from entering the tenant space from the stairwell. The existing hollow metal frame is filled with grout, and prepped for 3 hinges and reinforced for a roller strike. The existing hollow metal door is prepped for rim fire exit hardware – a Von Duprin 99L-F-BE. The code that applies to this renovation is the 2015 edition of the International Building Code.
