Place it at the start of a warning scene, then follow it with the Dun Dun Dun sound before the reveal, and use the Social Credit Siren later when the situation escalates further in the same edit.

This is a 17-second alarm sound, the kind of signal used to alert people and mark an urgent moment. It feels urgent and insistent, creating a sense of pressure that makes listeners stop and pay attention straight away. That direct warning quality makes it easy to recognise, even in a busy edit, as a call to act now rather than background noise.
