A conventional panel groups devices into zones and tells you which zone is in alarm. An addressable panel gives every detector and call point its own address and tells you exactly which device triggered. Conventional suits smaller buildings; addressable suits larger or more complex sites where finding the exact device quickly matters.
Key takeaways
- Conventional: 'Zone 3, first floor'.
- Addressable: 'Detector 042, room 105'.
- Addressable usually costs more but saves time finding alarms and faults.
- Building size and layout usually decide.

03Which to choose
04Frequently asked questions
Is addressable always better?
It gives more information, but a conventional system can be the right, cost-effective choice for a small building.
Can I upgrade a conventional system to addressable?
It usually means a new panel and devices; some cabling may be reusable. It needs a survey.
How many zones does a conventional panel need?
Enough that each zone covers an area that can be searched quickly. Panels come in different zone counts.
