Carmel and Lake Carmel Fire Departments responded to an electrical fire yesterday afternoon.  It was reported by a phone call that came in on the 10-digit business line and officials are reminding residents to call 911 in the event of an emergency, not the non-emergency number.  Carmel firefighters happened to be at the station at the time of the call and the information was forwarded to the 911 dispatch center, directing the appropriate department for a response.  Carmel is an all volunteer force, which means the fire station is not staffed or manned 24/7, and members respond from home or work when the 911 dispatcher notifies them of an alarm.
