We had an electrical contractor come in to assist us with the panel as the equipment was far too elaborate for us to mess with. He disabled the faom generators to avoid a huge mess and interruptions to business.
What we did was push around a wheeled cart with a metal pan on it, filled with gasoline. In various spots we would toss in a match and within seconds the flame detection units would sense the fire and it would set off the alarm system. The alarms were interesting. There were BG-12s scattered about (This hanger was HUGE) and the signals were those large red loudspeakers, possibly made by Wheelock.
