Sounds exactly like the sirens my home town used to warn of a dangerous situation like a bad storm approaching, they also used it as a noontime, 6 oclock, and 9 oclock, warning. When the 9er went off I knew it was time to head home soon. We could hear the siren in every part of town, about an area the size of Crestview. If it went off at any other time than normal, it would go continuosly until an all cear was declared. So it was obvious that it was an emergency warning.
