The panels and devices in an addressable system must be listed for use with each other.

• A. True
• B. False
• C. Only for some devices
• D. Not required

Answer: (A)

In an addressable fire alarm system, panels and devices are designed to work together as a coordinated set, and their compatibility is verified through listing. The listing confirms that the panel and each device’s signaling protocol, addressing scheme, power needs, and fault/alarm behavior have been tested as a matched combination. This ensures reliable communication and correct operation when the device reports its status to the panel. The authority having jurisdiction (or the listing agency) requires that only listed pairings be used, so using equipment not listed for use with a given panel can lead to unpredictable performance and non-compliance. Therefore, the panels and devices must be listed for use with each other.
