Put it at the start of a rescue or chase scene, then follow it with the Social Credit Siren for a second alarm, and finish with a Vine Boom when the supposed emergency turns out to be nothing at all.
About this sound
This is a nine-second ambulance siren that alternates between a high tone and a low tone in the classic hi-lo pattern, with a slightly off, unusual wobble that makes it sound less polished than a standard emergency siren. It feels urgent and attention-grabbing, but the odd pitch shift adds a strange, almost comic tension that keeps it from sounding like a real callout.
