TUCSON, Ariz. (AP) -- The Pima County Sheriff's Department has identified two issues related to why its new 911 system failed for 23 minutes.
The outage Monday afternoon affected 54 callers to the emergency line.
The department's dispatch center moved last weekend to a new 911-dispatch center in Tucson.
The new $102 million Pima County Wireless Integrated Network is a new emergency radio dispatch system that will allow first responders from various local agencies to talk to one another on radios.
Sheriff's officials say they're investigating to determine what caused the outage from 2:43 p.m. to 3:06 p.m.
The areas affected were unincorporated areas in the county, including Sahuarita.
Of the 54 missed calls, 26 were either duplicate calls or internal testing calls. Eighteen of the remaining calls were contacted to determine their emergencies.
