Don't forget the other half of the comment...evacuation. If the egress plan includes zoned evacuation, in lieu of general building evacuation, then the flow switch used to move folks from one smoke compartment to the other will need to align with the compartments and the voice evacuation messages. If egress plans tell you to move across a fire/smoke barrier but the fire alarm message is playing or partially playing in that zone, then you have a problem. Sections 9.6.3 and 9.6.7 in NFPA 101 provide some direction. However all of this is a design choice and process that must be coordinated during the design development phase, not during shop drawing development.
Forward the comment to the AE for resolution.
