What do room volume calculations help determine in SHS design?

• A. The color of detectors.
• B. The cost of the system.
• C. Calculations of room volume and design concentration to determine agent quantity.
• D. The required maintenance schedule.

Answer: (C)

Room volume calculations are used to determine the amount of clean agent required and the design concentration for the space. The protected room’s size sets how much agent must be present to reach the target concentration that will extinguish the fire. This design concentration is chosen to be effective while staying within occupant safety and code limits, and the resulting agent quantity comes from applying that concentration to the room’s volume considering distribution and potential leakage. Other options don’t fit because the color of detectors, system cost, or maintenance schedule aren’t directly dictated by the room’s volume in the design calculations.
