911 dispatch center experiences power disruption overnight

San Francisco’s 911 dispatch center experienced a power disruption overnight, prompting dispatchers to manually report emergency calls for several hours.

The 911 dispatch center, located on Turk Street between Laguna and Gough streets, partially lost power at 11:47 p.m. Thursday “as a result of human error,” emergency management department spokesperson Francis Zamora said.

The outage included desk radios temporarily going out of service, which came back on shortly after midnight. In the meantime, dispatchers used hand held radios to handle calls, Zamora said.

Also down overnight was the computer aided dispatch system, which allows dispatchers to input caller data that’s then transferred to radio dispatchers, who send that information to units in the field.

When the computer system went down, dispatchers began operating in manual made, meaning when a 911 call came in, someone would run that information over to radio dispatchers to summon fire or police services.
