While responding, 60 control re-dispatched and upgraded the alarm due to the alarm company stating that the premise reported that there was a a fire in the building. Bedford Hills TL57 was added to the assignment due to Mount Kisco's TL14 being out of service for maintenance. 2283(2nd Asst . Chief Hughes) and E104 arrived on scene and started their investigation as E105, R31 and TL57 arrived soon after. E104's crew determined that there was a fire in the kitchen exhaust system that had been extinguished by the built-in Ansul system. Crews vented the building to remove any smoke. The scene was turned over to the Mount Kisco building department and the Westchester County Health Department. All units were back in service by 13:53hrs.
