What must a licensee authorized to certify fixed fire extinguishing systems place upon completion of installation?

Upon the completion of the installation of fixed fire extinguishing systems, a licensee is required to place an installation label. This label serves as an important identifier that indicates the system is installed according to the relevant codes and standards. It provides essential information such as the date of installation, the type of system, and the name of the individual or company responsible for the installation.

The purpose of the installation label is to ensure that the system is recognized as compliant with safety regulations, which is critical for both fire safety professionals and in the event of an emergency. It informs subsequent inspectors, maintenance personnel, and users about the installation's legitimacy, facilitating proper operation and maintenance over the lifespan of the system.

The other options, while significant in their own context, serve different purposes in the lifecycle of fire safety equipment—such as providing proof of service or maintenance rather than the initial installation verification.
