At what occupant load is a fire alarm system required for Assembly Occupancies?

• A. Less than 100
• B. 100-299
• C. 200-299
• D. 300 or Greater

Answer: (D)

The key idea is the occupancy-based requirement for firing alarm systems in assembly spaces. In assembly occupancies, a fire alarm system is required when the occupant load reaches 300 or more. This threshold reflects the increased complexity of evacuating a larger crowd and the need for automatic warning to occupants and responders. Occupant load is determined by calculating how many people the space can accommodate, using code-approved factors, and once you hit or exceed 300, the alarm system becomes a code requirement. For lower loads, the rule isn’t triggered by occupancy alone, though other protections may still apply.
