What does Listed mean in the context of equipment lists?

• A. Approved
• B. Labeled
• C. Listed
• D. Certified

Answer: (C)

In this context, Listed means the equipment has been evaluated by a recognized independent testing laboratory and found to meet the applicable standards for fire protection equipment. The listing applies to a specific product model and standard, and the product carries the listing mark from that lab. This indicates it’s suitable for use in a residential sprinkler system when installed according to the listing’s instructions. The listing gives the authority having jurisdiction confidence that the item meets performance and safety requirements, beyond simple labeling. It differs from being simply approved (permission from an authority) or just labeled (identification on the item) or certified (a broader or different certification process). So the term on equipment lists points to third‑party verified compliance with standards.
