Fire Alarm Question! Smoke detector/Flashing strobe in a living room of a small condo?

[Cartoon1]

A two story small condo building.

• Two condos on first floor, Two condos on second floor. The condos on first floor and second floor are separated by an exterior corridor.
• This building will be sprinkled
• This is in the state of Florida
• Total of 4 condos in the building
• An R-2 Type building
• Ceiling between first floor and second floor is 1-hour fire rated

I'm adding smoke/carbon monoxide sensors in condo sleeping rooms and the corridor that is connected between the sleeping room.

My Questions:

• Is a manual fire alarm system for the exterior corridor between the building required? Based on the local code below my answer is a 'no'.
• Are flash strobe/smoke detectors required in a living room? My answer is a 'no'.

Please let me know if im missing something that i overlooked.

There is also an exception...... for buildings with water sprinklers so that is another one to help with the argument
