Configuring the Input Contact Isolator Settings
The Input Contact Isolator (ICI) is an optional, eight-channel input board for up to eight external user
alarm or message inputs to be routed to the Static Transfer Switch 2 Power Distribution Unit's alarm
network.
The contact is set to either be normally open or normally closed. When a contact closes or opens, an
event is triggered. See 6.2 - Input Contact Isolator Board for more information on the ICI.
The Input Contact Isolator options are configured through the Input Contact Isolator dialog box,
which is accessed from the Comm Options dialog box. The Input Contact Isolator dialog box contains
eight choices to match the eight channel input board. You can label each button to identify the event
associated with the contact. When the dialog box is accessed, each button flashes to display the Input
Contact Isolator number and the user entered label. This label also appears in the Display Panel
when an event related to an Input Isolator Connector is triggered.
The Input Contact Isolator dialog box allows you to:
• Label the input contact assignments for your setup.
• Set the delay for an external event triggering an alarm.
• Review the isolator contact assignments, once the labels are entered.
The delay allows you to set the number of seconds which a condition needs to persist to trigger an
alarm.
These input alarms can also be configured to activate a programmable relay output, which is dis-
cussed in Configuring the Programmable Relay Board Settings on page 109.
To configure the Input Contact Isolator relays:
1. Select INPUT CONTACT ISOLATOR from the Comm Options menu.
The Input Contact Isolator dialog box is displayed.

naming the button FAN.
