Tri-Township fire crews responded to a fire alarm on 1400 North 30th Thursday night.
Officials say they saw smoke coming from inside the building and arrived on scene at about 10:30 pm.
Fire lieutenant Andrew Wittler says an electrical conduit sparked the fire, which triggered the building’s sprinkler system.
Wittler says the sprinkler system was effective in preventing the fire from growing, and helped crews extinguish it quicker.
Wittler says the building was unoccupied at the time and reported no injuries.
