Installation ANN-BUS Devices
N-ANN-I/O Connection to FACP
The N-ANN-I/O connects to the FACP via the ANN-BUS as illustrated in Figure 2.25. After the
N-ANN-I/O is connected to the panel, it must be added to the system via FACP programming.
N-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 resistors are required. LED
outputs are mapped to output circuits. Refer to the section titled “ANN-I/O LED Zone Assign-
ments” on page 85 of this manual.
