Siren technicians identified a degraded component that required replacement to fully restore the outdoor warning siren system to operational status. Extensive testing was completed to improve reliability and prevent past false alarms. We appreciate the communities feedback and encourage reporting any issues to Linn County Emergency Management Agency.

The Linn County outdoor warning siren system is tested monthly, with the test taking place on the first Wednesday of the month at 8:45 a.m. The test consists of a computer-generated voice announcement, “This is a test. There is no emergency”. Followed by an audible, short up and down wailing and a steady wailing alert.

Linn County Emergency Management Agency also encourages residents to sign up for Alert Iowa, the State of Iowa’s official emergency notification system. Through Alert Iowa, local officials use a single, statewide notification system that provides local control of how and when to disseminate emergency and public safety messages to residents. Residents can learn more about the system and sign up for alerts on the Iowa Department of Homeland Security website: https://homelandsecurity.iowa.gov/alert-iowa/.

If you have any questions regarding the operation of the Outdoor Warning Siren System within your community, please contact the Linn County Emergency Management Agency at 319-892-6500.
