ANN-BUS Devices Installation
ANN-I/O Connection to FACP
The ANN-I/O connects to the FACP via the ANN-BUS as illustrated in Figure 2.18. After the
ANN-I/O is connected to the panel, it must be added to the system via FACP programming. Refer
to the section titled “Modules Installed” on page 96.
ANN-I/O Module LED Wiring
There are four 12-pin connectors on the 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 can be mapped to output circuits. Refer to the programming section titled “Modules
Installed” on page 96 of this manual.
