The communications center, on Egg Harbor Road, handles requests for firefighters and EMS services for 37 county towns and police services for 32 towns, Keashen said. Other employees remained in the center and dispatchers returned to the building in about an hour, he said.

The electrical problem in the server room occurred shortly before 1 p.m. and did not cause a fire, Keashen said. Employees went through a drill in March that simulated a similar scenario, he said.
