ANN-I/O Connection to FACP
The N-ANN-I/O connects to the FACP via the ANN-BUS as illustrated in Figure 2.23. After the N-ANN-I/O is connected to the panel,
it must be added to the system via FACP programming. Refer to the section titled "ANN-I/O Options" on page 87.

ANN-I/O Module LED Wiring
There are four 12-pin connectors on the N-ANN-I/O module for connecting LEDs. Each set of 10 LEDs get their power from Pin 11 of
the corresponding connector. Internal resistors are sized so that there is approximately 10 mA of current for each LED. No series resis-
tors are required. LED outputs can be mapped to output circuits. Refer to the programming section titled "ANN-I/O Options" on page 87
of this manual.
The LEDs are wired as illustrated in Figure 2.24. Note that the illustration depicts only connectors P1 and P2. Wiring is identical for P3
(LEDs 21-30) and P4 (LEDs 31-40).
