It may help if you say which system you have.

Just standard domestic wired interlinked smokes not sure which brand they are sorry - is there a sounder box for unversial use?

Relay base such as https://www.aico.co.uk/product/ei128rbu-hard-wired-relay-module-with-battery-back-up/

The relay must be from the same manufacturer as the alarms, but it can then switch any sounder or other device.
