Apartment Building, Residential DeKalb, IL – Sprinkler system keeps flames from spreading in apartment fire July 20, 2015 viking210 The DeKalb Fire Department responded to an apartment fire at 832 Ridge Drive in DeKalb at 11:09 a.m. Saturday. The cause of the fire is still under investigation, said Jeff McMaster, deputy fire chief, later that afternoon. “When firefighters got there, there was a light smoke coming from the bathroom,” McMaster said. “When they got in, the sprinklers were on.” The sprinkler system had kept the flames contained and the firefighters were able to put the rest out upon arrival, McMaster said. No one was home at the time, McMaster said. A neighbor had seen the smoke, heard the apartment’s fire alarm and made the call. There were no injuries, McMaster said. He estimated the damage at about $5,000.
