QuickAlert NACs. A pre-signal application that uses QuickAlert NACs is
programmed in virtually the same manner as the standard NAC example shown
above. The two differences for QuickAlert are that it requires one additional
equation to turn the horns off and you cannot use Class A QuickAlert with a pre-
signal application. (The horn pattern generated by the Sync module is set via a
switch, and it cannot be controlled by Custom Control.) Figure 4-2 shows an
example of a pre-signal application that uses QuickAlert NACs.
