Which statement about listed equipment is correct?

Which statement about listed equipment is correct?

• A. It has not been tested
• B. It has been listed
• C. It has been tested and found suitable for its specified purpose
• D. It has been listed as consumer electronics only

Answer: (C)

Listing means a product has been tested by a recognized laboratory and shown to meet specific standards for a defined use. Because of that, the statement that it has been tested and found suitable for its specified purpose best captures what listed equipment signifies. Listing follows evaluation and confirms suitability for the intended application, not just that the item exists as a listed product. It isn’t correct to say it has not been tested, and listing isn’t limited to consumer electronics only, since it applies to devices specifically approved for fire alarm system use.
