MADISON, Wis. --
The Madison Fire Department said that four sprinkler heads extinguished an early-morning fire at Madison Newspapers Friday.
Madison Fire Department spokesman Eric Dahl said the automatic fire sprinkler system activated when a compressor caught fire in a mechanical room at the facility at 1901 Fish Hatchery Road.
Fire crews were dispatched to the fire at 2:45 a.m. Friday. Employees were evacuating the building when firefighters arrived at the scene.
Firefighters observed smoke and entered the room to confirm that the fire was out and to turn off the flow of water. Electricity was also turned off as a precaution. All units had cleared the scene by 5:30 a.m.
Dahl said no injuries were reported.
Dahl said the fire caused approximately $52,000 damage to the building and equipment.
Investigators have not pinpointed a cause, but said they believe the fire was unintentional.
