Warning Sirens and Testing


A contracted service technician performing radio maintenance on the warning sirens in the City of Three Rivers inadvertently activated the system Thursday afternoon. The activation was caused by human error, and was not caused by defective equipment or system failure.

“The radio work being done was not supposed to trigger an activation, and we were told that the radio repairs could be tested without actually sounding the sirens”, according to Dan Tomlinson, Fire Chief. “Our redundant activation process surprised the technician, otherwise we would have given adequate notice to the public before initiating the work.”

 The service contractor reported that all of the components passed inspection and confirmed that the system was back online and functioning properly before releasing the system back to the city.

However, a full test of the system will be conducted Saturday, October 30, in the afternoon. Multiple short tests will be necessary to confirm that all of the activation points are functional.
