Place this siren at the start of a rescue or arrival sequence, before the main action begins, then follow it with the Dun Dun Dun Sound Button when the problem is revealed. Keep it as the opening cue only, and let the next sound carry the payoff.

This clip is a Dutch fire engine siren, the wailing two-tone brandweer alarm heard for about twelve seconds as the vehicle passes. It feels urgent and tense, instantly putting listeners on alert like an emergency is unfolding nearby, with that rising and falling wail building pressure the whole time.
