Annunciator Key Switch (AKS-1) or Shunt Plug
The AKS-1 provides access security for the control switches on the INA. The AKS-1 kit includes a key and hardware for
mounting to the ABF-4. Unless intended for use as the network point of acknowledgment, the AKS-1 or the shunt plug
(part number 08125) must be employed (refer to Figure 2.2.2-2). When employing the AKS-1, the switch must be mounted
to the ABF-4 trim plate. Plug the switch leads from the AKS-1 into Connector J3 on the INA. To disable the keypad, install
the shunt plug across both terminals of Connector J3 on the INA . Install the shunt on only one terminal of Connector J3
to enable the keypad. The INA keypad must be disabled via the AKS-1 or shunt plug when not in use.
