Скачать или смотреть Whelen WPS-2909 siren ambiance | Houston County, GA | 1/16/2021

About 10 minutes after noon, the county's sirens finally came to life for their monthly test, and this is what they sound like from my vantage point. Our house is nearly centered between about six of their sirens (all Whelen WPS-2909s), with the closest one being just over a mile away to the south. The strong north wind wasn't exactly working in my favor today, making it somewhat difficult to hear the more distant sirens that you would normally be able to, especially during the voice announcements. They do eventually become much more audible as each one starts up in the alert tone, as you'll hear around the one minute mark.

Interestingly, one of the sirens in the distance apparently has a logic board with the older firmware that produces the 435Hz alert tone. I have yet to pinpoint exactly which unit that is, though I have a hunch it's somewhere to our northeast, toward the Bonaire area.

Houston County, GA's outdoor warning system is tested on the third Saturday of each month at approximately 12:00 noon, pending clear weather conditions. In the event of inclement weather, the test is postponed until the following (fourth) Saturday as long as the weather permits.
