Exit access doorways

Given a large conference room, OL of 114, within a larger B occupancy. There are three doors "serving" the room, one is outswing directly to the exterior (exit only), one is outswing to a lobby that leads to the main exit discharge, one is swinging into the room from a corridor that leads to two other exit discharge locations. The two outswing doors are marked exits, the other is not. I am questioning whether the inswing door is compliant in any way. My logic is that it is an exit access door, it "serves" a room with an A occupancy occupant load > 49, therefore it must be marked with exit signs and EM lighting, it must swing in the direction of travel, and it must be equipped with panic hardware. Furthermore, every exit access door between it and both of the exit discharge locations must meet the same requirements. The exit access path from that door is pretty convoluted, but it is VERY likely the one that will be used by the occupants in a non-emergency basis as the other two don't offer a convenient way to get back to the work areas of the B occupancy, where MOST of the occupants will come from MOST of the time.

I have never questioned this before but I am getting pushback on my comment that every door serving that space must meet the requirements all the way out.
 
You won't get a clean answer on this.....IF it is provided for egress, it meets chapter 10......

1010.1 General

Diagram
Doors in the means of egress shall comply with the requirements of Sections 1010.1.1 through 1010.3.4. Exterior exit doors shall also comply with the requirements of Section 1022.2. Gates in the means of egress shall comply with the requirements of Sections 1010.4 and 1010.4.1. Turnstiles in the means of egress shall comply with the requirements of Sections 1010.5 through 1010.5.4.
Doors, gates and turnstiles provided for egress purposes in numbers greater than required by this code shall comply with the requirements of this section.

"one is swinging into the room from a corridor that leads to two other exit discharge locations."

I don't see an IF there. The three doors are egress doors and shall meet the requirements chapter 10.

2020 CBC:
1010.1 Doors. Means of egress doors shall meet the requirements of this section. Doors serving a means of egress system shall meet the requirements of this section and Section 1022.2. Doors provided for egress purposes in numbers greater than required by this code shall meet the requirements of this section.

The wording is poor. The word "provided" is sometimes interrupted to mean "intended". That give leave to imply that the extra door is not part of a means of egress. A better word would be "installed". That puts a rope around the intent and there is no room for confusion. IF the door is there and IF it leads to an exit, the door is part of a means of egress.
