4.11 Auxiliary - Reverse Polarity Signaling
The following is a wiring diagram utilizing a NAC circuit or 55000-825ADV addressable NAC module for reverse
polarity signaling to a remote location (see figure 36).
Note: A “Not” statement will need to be created for the trouble contact activation, so that an alarm
condition has a higher priority than a trouble condition (consult factory).
