It is a 1 1/2 hour fire rated door embedded along a 2 hour fire rated wall that creates an exit to safety inside of a building. Codes give maximum travel distances to get to safety, i.e. to exit a building. However, some buildings are so large (Casino's, Hotels, Convention Centers) that it is impossible to get someone out of the facility within the maximum distance. Therefore, to comply with the code, a fire rated wall is constructed with fire rated doors to contain the fire and allow occupants to exit into a safe part of the building.

Does exit access include exit?

No, under the definitions in the NFPA Life Safety Code, a "means of egress" includes an exit access, an exit and an an exit discharge. In that sense, "exit access" is everything an occupant must pass through on the way to an "exit", where an "exit" is a door to a safe place, either a fire door into another fire partition, a door outside, a fire door to a smokeproof stairwell, or a fire door into an "exit" comprised of a protected horizontal passageway. In other words, you use an "exit access" to get TO an exit, and you use an exit to get to an exit discharge (which reaches a public way). Examples of exit access would include any distance through an unprotected space on the way to an exit, whether it's across an open warehouse floor, across theater seats and down an aisle, or going down an unprotected stairway. Since those areas are not fire-resistant, they are "exit access".
