How many newly installed sprinkler heads require a new installation tag?

• A. 10
• B. 20
• C. 5
• D. 30

Answer: (B)

Grouping newly installed sprinkler heads into sets helps keep installation records clear and manageable. The rule is to attach a new installation tag for each group of heads up to twenty. In practice, one tag covers the first twenty heads; once you reach twenty, a second tag is required for the next set, and so on. For example, installing twenty heads needs one tag, installing twenty-one to forty heads needs two tags, and so forth. This is why twenty is the correct grouping unit—the tag count scales with the number of heads installed. The other options would imply tagging in smaller or larger increments that don’t align with how the tagging is intended to track installations.
