Replacement rule: Addressable devices are usually not interchangeable across brands or protocols. Conventional and notification devices still need voltage, listing, sync, candela, and compatibility review.

Field Checklist

Before approving a replacement

1. Same system family

Confirm the replacement is listed/approved for the exact panel family, protocol, and firmware.

2. Base / module fit

Check detector bases, isolator bases, relay bases, module terminals, mounting box, and wiring class.

3. Programming impact

Confirm address method, device type, mapping, sensitivity, control-by-event, and description changes.

4. Power / sync / candela

For notification appliances, match voltage, candela, sync protocol, wall/ceiling type, and environmental listing.

5. Documentation

Record existing model, replacement model, location, circuit/address, test result, and any limitations.

6. AHJ / customer review

For design-impacting changes, verify approved drawings, customer standard, and AHJ expectations.
