| event text = Offsite Public Prompt Notification System, Sirens and Tone Alert Radios were inoperable for greater than one hour. The Primary Console for siren operation at Houston County was found to be non functional at [approximately] 0820 CST during periodic siren tests. The backup console did successfully operate the sirens. However, at 1030 CST the transport system for actuating system failed at Webb, AL and the Backup Console for siren operation as well as Tone Alert Radios became inoperable. The inoperability of the system lasted for one hour and five minutes, being restored at 1134 CST. Initial troubleshooting indicates the problem was with the fiber coaxial cable to the demultiplexer in the transport. The problem could not be repeated, and investigation continues. Repairs for the Primary Console for siren actuation are being facilitated. | | event text = Offsite Public Prompt Notification System, Sirens and Tone Alert Radios were inoperable for greater than one hour.
