FFD said firefighters responded to Superior Essex at 120 Southeast Parkway just after noon Sunday.
When they arrived, firefighters found smoke coming from the roof of the 320,000-square-foot industrial building that manufactures magnet wire, FFD said.
Battalion Chief Tyler Crews said the fire originated in machinery and was contained to the equipment and a three-story vent tower that extended to the roof.
“Crews said the fire was partially controlled with the help of the building’s automatic fire sprinkler system,” FFD said.
Several FFD crews were dispatched to the scene due to the size of the facility. FFD said two tower trucks, two ladder trucks, three engines, a rescue truck, an air truck, a battalion chief and two district captains responded to the fire along with the Franklin Police Department and Williamson Health EMS
FFD said responders were on scene for about two hours.
“Crews said power was restored to approximately half of the building, and a limited number of employees were permitted to return to work in the front portion of the facility,” FFD said.
No injuries were reported in the fire, and the cause has not been determined.
