Which entity verifies that a sprinkler model meets listing criteria?

• A. Building owner
• B. Recognized listing agency
• C. Local authorities
• D. Insurance company

Answer: (B)

The key idea is that listing is a formal certification carried out by an independent, recognized third party. A recognized listing agency tests and evaluates a sprinkler model to ensure it meets the applicable standards, and then issues a listing if the design, materials, and performance align with those standards. This is the official verification that the model is suitable for use per the codes in force. Examples of such agencies include UL, FM Global, and ETL, which are recognized by authorities having jurisdiction.

The building owner isn’t the one validating the listing, and local authorities enforce compliance with codes but rely on the listing to demonstrate conformance. Insurance companies may require listing and review risk, but they don’t perform the listing verification themselves.
