Title	Inability to Initiate Emergency Sirens from Emergency Operations Facility
Event Description	At 0322 CST, on 11/24/2003, an alarm was received on the Alert Notification System. The system alarm is not necessarily indicative of a system fault. Normal procedure is to check the system at the start of the normal work day. When the system was tested at 0615 CST it was discovered that the emergency sirens could not be sounded from the Emergency Operations Facility (EOF). Troubleshooting efforts were begun. The repair crew discovered that the sirens are able to be sounded by their normal stations (the counties). The sirens were also able to be sounded by a remote unmanned alternate location [owned by the utility located in downtown Omaha]. However, the EOF could not have verified which sirens had sounded. Verification of siren actuation was possible from the unmanned alternate location. Troubleshooting continues. The licensee has informed the NRC Resident Inspector.
