In an addressable fire alarm system, how is a device typically identified during testing?

• A. Reading the device's address on the panel and cross-referencing with the building map
• B. Visual labeling on the device
• C. Checking the color of the wiring
• D. Using the room number

Answer: (A)

In an addressable fire alarm system, each device has a unique address stored in the panel. During testing you read that address from the panel to identify which device is being tested, then cross-reference it with the building map to locate its exact physical position. This direct link between the panel’s digital identification and the real location keeps testing precise and well-documented, which is essential in large facilities. Relying on visual labels can help but isn’t foolproof—labels can wear off or be wrong. Wiring color isn’t a standardized or reliable way to identify devices, and room numbers alone don’t tie the device back to the panel’s exact address. Using the panel address and the map ensures accurate identification and traceability of every tested device.
