You're right to question Item #2, as it's often misunderstood in single-story buildings. Let's break down how it applies (or doesn't) to your specific situation: The Issue

In a single-story building, everything is at the "level of exit discharge". There is no above or below the level of exit discharge.

Florida Building Code Commentary

The intent of this provision is to address situations where a significant number of occupants are located on floors other than the level of exit discharge, such as basements or upper floors.



Your Situation

Because your building is single-story, your occupant load is not more than 100 persons above or below the level of exit discharge. Item #2 therefore does not apply and does not trigger the requirement for a manual fire alarm system.

Other Considerations

With a single-story Group B occupancy, not sprinkled, and an occupant load of 200, the only applicable requirement is Item #1: "The combined Group B occupant load of all floors is 500 or more". Since your occupant load is only 200, and this applies to all floors combined, Item #1 does not apply.

The Exception

As you rightly point out, the exception applies if you had a sprinkler system installed in accordance with section 903.3.
1.1 (NFPA 13). If your fire sprinkler system will activate upon sprinkler water flow then a manual fire alarm box isn't necessary. Since you do not have a fire sprinkler system the exception does not apply.

Conclusion based solely on the information you provided

Your building does not need a manual fire alarm system based solely on the conditions outlined in Florida Building Code Section 907.2.
