All fire detection devices shall be listed or approved for the purpose for which they are intended.

• A. True
• B. False
• C. It Depends
• D. Not Specified

Answer: (A)

Devices used in fire detection must be listed or approved for the purpose they are intended to serve. This ensures that recognized testing laboratories have evaluated the device for its specific role—whether it’s detecting smoke, heat, or flame—and that it meets the relevant standards, performance criteria, and environmental limits. The listing or approval also confirms the device will be compatible with the fire alarm system’s power, wiring, and signaling requirements, so the system operates reliably as a whole. Codes and standards, such as NFPA 72, require that devices be listed or approved for their intended use, and authorities having jurisdiction typically will not accept unlisted equipment. Using non-listed devices can lead to noncompliance, void warranties, and increased risk of system failure. So the statement is true.
