Alarm Expansion Panel

The optional ONS 15454 alarm expansion panel (AEP) can be used with the Alarm Interface
Controller-International card (AIC-I) card to provide an additional 48 dry alarm contacts for the ONS 15454,
32 of which are inputs and 16 are outputs. The AEP is a printed circuit board assembly that is installed on the
backplane. Figure 1-31 shows the AEP board; the left connector is the input connector and the right
connector is the output connector.
The AIC-I without an AEP already contains direct alarm contacts. These direct AIC-I alarm contacts are
routed through the backplane to wire-wrap pins accessible from the back of the shelf. If you install an AEP,
you cannot use the alarm contacts on the wire-wrap pins. For further information about the AIC-I, see the
AIC-I Card.
