System Operation:
a. The operation of a station, manual or automatic, shall cause a continuous general alarm
to sound on all devices, cut off stipulated fans and mechanical equipment, until the station
is restored to normal.
b. System shall be supervised and a line fault or shift from main to stand-by power shall
