Business Occupancy 2 story - There is a suite that has sensitive information on both sides of the main egress corridor leading to the stair. (One of two stairs on the floor.) If the suite needs blocked off as a whole from the rest of the floor for security reasons, can a door be placed in the middle of the corridor and release on the fire alarm?
