AIC and AIC-I
The ONS 15454 Alarm Interface Controller (AIC) and Alarm Interface Controller-International (AIC-I) cards provide customer-defined (environmental) alarms and controls and support local and express orderwire. The AIC-I provides twelve customer-defined input and four customer-defined input/output contacts. The physical connections are via the backplane wire-wrap pins. If you use the additional alarm expansion panel (AEP), the AIC-I card can support up to 32 inputs and 16 outputs, which are connected on the AEP connectors.
