Right. The situation doesn’t require a land asap. As mentioned above there are no crew actions required, the system brings to your attention you have lost fire/overheat detection on the engine.
Having discussed the scenario with some colleagues it came up continuing would be reasonable, also if Ops agrees and can fix the plane at destination.
We still have engine primary and secondary parameters to monitor a possible malfunction, and possibly liaise with engineering for further info.
It’s a bit of grey area though .
