The AIC-I card provides direct alarm contacts (external alarm inputs and external control outputs). In

Note

the ANSI shelf, these AIC-I alarm contacts are routed through the backplane to wire-wrap pins

accessible from the back of the shelf. When you install an AEP, the direct AIC-I alarm contacts cannot

be used. Only the AEP alarm contacts can be used.

Step 1

Remove the two backplane screws. Replace the two screws with standoffs. Insert the longer standoff on

This procedure installs an Alarm Expansion Panel (AEP) onto the

15454-SA-ANSI shelf backplane. The AEP provides alarm contacts in

addition to the 16 provided by the AIC-I card. Typically, the AEP is

pre-installed when ordered with the ONS 15454; however, the AEP can be

ordered separately.
