WAUSAU - North Central Health Care blames an "undetermined device failure" for the alarm and lock down in Wausau earlier this month.
A statement released Wednesday said the internal investigation ruled out human activation or remote activation of the emergency alarm.
Earlier this month, emergency crews locked down the hospital and surrounding area after a "Dr. Black" emergency was triggered. That alarm indicates a dangerous person with a weapon. After searching the facilities, no sign of an armed person was found anywhere in the hospital.
NCHC also said that the emergency system was scheduled to be replaced prior to the incident. The alarms had been tested recently and showed no malfunctions.
Law enforcement, emergency response, and NCHC will be meeting in early June to further review the incident.
