Place it at the end of a setup, after the dramatic dun dun dun builds suspicion and just before the reveal, then follow it with a vine boom for the payoff. For a failed escape, pair it with a SpongeBob fail sting instead, letting the siren lead and the fail sound close the scene.

This three-second clip is a classic police siren in full wail, its tone rising and falling in the familiar two-note pattern that signals officers are approaching. It feels urgent and slightly panicky, turning a calm scene into a chase or a bust in an instant. In Chilean Spanish, pacos is slang for police, so the name simply means the officers' siren.
