Title | Offsite Notifications Made Due to Inadvertant Activation of Six Epz Sirens |
Event Description | At 0855 six sirens had been activated by the Ottawa County dispatch console for 3 minutes.
At 0905 Ottawa County Sheriff Dispatch Center notified [the licensee] that sirens in Ottawa County had been inadvertently activated. It appears this was caused by the county radio service vendor resetting the dispatch center consoles during trouble shooting of the sheriff's radio system. Immediate actions taken: RA-EP-00420, Response to Prompt Notification System Malfunction, was implemented. The siren system was polled and the data from the Emergency Operations Facility (EOF) siren computer was reviewed. The computer data indicated at 08:55:55 the six sirens located in Bay Township had been activated by the Ottawa County Dispatch Console for 3-minutes. Fleet siren maintenance was contacted and requested to come to Ottawa County to meet with the radio service vendor to determine the cause of the inadvertent activation. In addition, NOP-LP-5001, Communicating Events of Public Interest, was implemented and associated notifications were made. These notifications included the State of Ohio, Ottawa County, and Lucas County. The NRC Resident Inspector was notified by the licensee. |
