A functional block diagram depicting the interconnections between modules is
shown in Figure 3. Alarm signal and 0V connections provide alarm and trouble
operation. The host FACP can detect EARTH faults on any NAC signal.

Hardware Configuration DIP Switch SW1
The 8-position Hardware Configuration DIP Switch (SW1) is used to configure
w
hat hardware is present and supervised by the 4009 IDNet. For proper 4009
IDNet operation, SW1 must correspond with the hardware installed. The
hardware configuration switch is located at the top edge of the system board (see
Figure 4). The “ON” position of the switch indicates that the associated
hardware (see Table 1) is configured to the 4009 IDNet. A trouble condition is
reported to the FACP if hardware is configured, but not present or hardware is
present but not configured. Dip Switch SW1/Position 8 controls how the 4009
IDNet receives it commands. When SW1/Position 8 is “ON”, the 4009 IDNet
receives commands from the control inputs. When SW1/Position 8 is “OFF”, the
4009 IDNet receives commands from the IDNet channel.
