A system with predetermined flow rates, nozzle pressures, and agent quantities is a what type of system?

• A. Custom
• B. Pre-engineered
• C. Manual
• D. Hybrid

Answer: (B)

This item tests recognizing standardized, factory-built systems that use fixed performance parameters. A pre-engineered system is designed with predetermined flow rates, nozzle pressures, and agent quantities chosen to meet specific hazard requirements, and the components are manufactured and tested to those specs. This creates consistency, easier installation, and clear documentation of what the system will deliver. A custom system would be designed from the ground up for a particular site and might involve on-site engineering and adjustments, not fixed factory parameters. A manual system relies on operator actions or field tweaks rather than fixed automatic specifications. A hybrid system combines elements of different approaches, but the defining trait—predefined performance targets—still points to a pre-engineered solution.
