Aztalan Bio will be testing their Emergency Speaker System this Thursday, May 14. Beginning in June, testing will continue on the first Thursday of each month.
This system is a Whelen emergency speaker system designed to broadcast over a large area and may be heard unexpectedly by residents.
These tests will not conflict with Jefferson County siren testing. We are sharing this in advance to help avoid confusion or concern.
If you have any questions or concerns, please feel free to reach out directly to Aztalan Bio at (920) 931-4792.
