No one was hurt.
A sprinkler helped control a fire Friday evening at the Aeroflex company on Spectrum Drive in Frederick.
Fire and rescue officials say the call went out around 5:47 PM for a water flow alarm. Fire fighters sent to the scene found a fire in a work area. The sprinkler system was activated and helped control the flames. Once the fire was extinguished, personnel worked to clean up the water and remove the smoke from the building.
There were no injuries.
The cause is under investigation. A damage estimate is not available.
