Where must the installation tag be securely attached on a fire protection sprinkler system?

• A. The riser of each system
• B. The main water supply line
• C. The sprinkler head
• D. The control panel

Answer: (A)

The main idea is that the installation tag should stay with the system where it can be seen during inspections and maintenance. Attaching the tag to the riser—the main vertical pipe where water enters and where most of the system’s components come together—keeps the tag with the actual system hardware. This makes it easy for inspectors and workers to verify installation details (date, contractor, and system specs) right at the point of service.

Putting the tag on the main water supply line, the sprinkler head, or the control panel is less reliable. The main line might be far from the installed components or could be altered during repairs; a sprinkler head is a replaceable part and may be serviced or swapped out, which could detach the tag; the control panel isn’t the central reference for installation details and might not always be in view during an on-site check. Binding the tag to the riser ensures it remains with the system and is readily visible when needed.
