Excerpts from the ChicagoSunTimes.com:

At 12:27 a.m. on Tuesday, the Evanston firefighters were returning from an automatic fire alarm when they smelled something burning in the area of the 2300 block of Ridge Avenue.

The firefighters parked and walked around Ridge Avenue, finding a two-story, single-family home with activated smoke detectors that was full of smoke. The home was rehabbed and unoccupied.

Crews upgraded the alarm to a Box Alarm, and several other agencies helped extinguish the blaze within 24 minutes. An Evanston firefighter was treated and released from the hospital for heat exhaustion.

No other injuries were reported.
