What is required to certify that a fixed ext. system was installed according to specifications?

To certify that a fixed extinguishing system was installed according to specified standards, an installation label is essential. This label serves as official documentation that confirms the system has been installed following the manufacturer’s instructions and relevant codes. It is typically affixed to the system or provided in documentation and includes crucial details such as the date of installation, the installer’s name, and relevant specifications.

While a final test report may indicate the system was tested satisfactorily, it does not serve to certify proper installation. A state inspector's approval can verify compliance with local regulations but may not cover all aspects of the installation as specified by the manufacturer. Similarly, the manufacturer's manual provides guidelines for installation, but the installation label specifically signifies that the system has been installed in accordance with those guidelines, making it the required documentation for that purpose.
