People calling 911 in Allegheny County should have no trouble connecting, but the county has kept active a backup number after technical problems caused some callers to hear only a busy signal this morning.
Alvin Henderson, chief of the county's Department of Emergency Service, said the uninterruptable power system, which keeps radio communications running during a power outage, went out around 7 a.m. after some sort of overvoltage or overcurrent, which causes breakers to trip or fuses to blow.
What exactly prompted that, however, was still unclear Thursday afternoon. Chief Henderson said Duquesne Light is looking into the matter.
County spokeswoman Amie Downs said callers should be able to get through, but an alternate number -- 412-473-3056 -- will ring straight to the 911 center through Friday.
The county said in a tweet shortly before 11 a.m. that its 911 center is now "fully operational."
Back-up systems were in place were in place this morning and dispatchers were using other channels to dispatch first-responders.
