@@mannyortega3340it’s the dispatch tones. All “typical” calls (medicals, public assists, etc) have a few beeps and high priority calls(structure fires, traffic collisions with entrapment, etc) get one long beep. That is for all metro net fire departments. (Orange, Anaheim, Newport Beach, Huntington Beach, Fullerton, brea, and maybe 1 more if I’m not mistaken.)
