Which information is critical in the record of installation for a sprinkler system?

The record of installation for a sprinkler system serves as a comprehensive account of the system's setup and its operational history. Installation details and maintenance records are essential components of this documentation because they provide crucial information regarding how the system was configured and any servicing it has undergone since installation.

Having the installation details allows for accurate assessment of the system's design and compliance with relevant standards, ensuring that it functions effectively in an emergency. Maintenance records are equally important, as they document inspections, testing results, repairs, and any modifications made to the system over time. This information is vital for verifying that the sprinkler system continues to operate correctly and meets safety regulations, thus ensuring the ongoing protection of the property and its occupants.

While other options may seem relevant, they do not encompass the breadth of information necessary for a thorough record of installation. Simply listing the installation date, future upgrade recommendations, or only the cost fails to address the comprehensive requirements stipulated in NFPA 13 for effective fire protection management.
