Which feature makes addressable devices more informative than analog devices?

• A. They cost more
• B. They require less wiring
• C. They can report specific zone numbers
• D. They are less reliable

Answer: (C)

Addressable devices provide precise localization by reporting the exact zone they belong to. Each device has a unique address and can send back a specific zone number when it changes state, so the control panel knows not just that something happened, but exactly where it happened. This detailed information lets responders target the right location, speeds up troubleshooting, and improves maintenance because you can see which device triggered the event. In contrast, analog devices typically indicate a general alarm for a circuit without identifying the specific device or zone, so the information is much less detailed.
