Which item is typically included in NICET SHS project submittals?

• A. System design drawings, calculations (room volume, design concentration, agent quantity), sequence of operation, wiring diagrams, equipment data sheets, coordination with other trades, and NFPA compliance.
• B. Only a general system description.
• C. Warranty information and service contracts.
• D. Color swatches of equipment.

Answer: (A)

Submittals for NICET SHS projects must present a complete, review-ready package that shows how the system will meet performance, safety, and code requirements. Including system design drawings and the detailed calculations (room volume, design concentration, and agent quantity) demonstrates exactly how the design will achieve the intended protection and agent distribution. The sequence of operation lays out how detection, release, interlocks, and alarms will function in real time, which is essential for safety and proper coordination with other building systems. Wiring diagrams translate the design into the control circuitry and enable correct installation, while equipment data sheets specify the exact models, capacities, and performance parameters to ensure components meet the specified requirements. Coordinating with other trades in the submittal helps prevent clashes in spaces, ceilings, penetrations, and service routes, which is critical for a smooth installation. Finally, showing NFPA compliance ties the design to recognized codes and standards, which is a fundamental part of review and acceptance by authorities having jurisdiction.

That broader, detail-rich package is what reviewers expect; a general description would not prove how the system will actually perform or meet standards. Warranty information and service contracts belong more to post-installation considerations, not the core submittal for design approval. Color swatches have no bearing on the technical and safety performance of the system.
