2.5.1  Configuring NACs
The Notification Appliance Circuits on the main circuit board are configured for Style 
Y (Class B) or Style Z (Class A) by properly orienting the NACKEY card in JP6 which 
is located at the top of the main circuit board near the NAC terminal blocks TB3 and 
TB4.  The default configuration is for Style Y (Class B).  Refer to Figure 2.7 for 
information on installing the NACKEY card.
