The 8-position Hardware Configuration DIP Switch (SW4) is used to configure what hardware is
present and supervised by the Addressable Controller, and how the hardware is used. The
Hardware Configuration Switch is located to the right of the channel indicator LEDs
(E-A indicators) on the system board (see Figure 1-2).
Table 2-1, below, lists the SW4 settings.
IMPORTANT: All settings, including “N/A,” will reinitialize the TrueAlert
Addressable Controller.
