On Wednesday Feb. 3, 2010 Hawthorne and Valhalla FD's were dispatched to 226 Linda Ave Hawthorne Cedar Knolls Main Admin building for an activated fire alarm/pull station. Units operating L56, E155, Valhalla FD 2481, TL49

Cross Streets of Bradford St. & Frankford St.

Weather Conditions sunny and cold

Upon arrival of 2481 , the chief was advised of a possible battery explosion for a backup to the central computer system for the main offices. All incoming units were directed to respond to the rear of building per 2481. Crews from L56 entered the building from the rear of structure to investigate. Upon investigation it was determined that there was no battery explosion but the main computer terminals had malfunctioned, over heated and caught fire. Crews from TL49 and E155 then started to ventilate the remaining floors of the structure. Once all hazards were eliminated the scene was turned over the campus maintenance crews and all units were returned to service.

Units were on scene for about 1 hr
