The City of Hannibal is upgrading its aging warning siren system to comply with federal regulations.
Hannibal currently has 16 tornado sirens. Eight units are nearing 50 years old and eight others were installed about a decade ago.
The mandated part of the upgrade will move the sirens to a narrow bandwidth. The city is also installing a talk back in 8 of the older sirens, allowing the emergency management agency to detect problems via computer. Director John Hark said both of these updates are a win win for the city.
"The narrow banding will give us a better communication on our radios between departments. Everything we're doing today is based on trying to improve the communications to where if we have a major event we can all talk to one another," Hark said.
According to federal regulations, the narrow banding upgrades must be complete by January 1st, or the city will be fined.
The cost of the upgrade is around 36-thousand dollars.
