• From the Select Input Menu, choose an input—for example, Device_1—and press Enter .

Table 13 shows the digital input features you may change, along with the default settings: you may change the name of the input, define it as normally open or closed, and specify it as alarmable or as an event.

Alarmable inputs may be defined as either Unlatched or Latched.

Event status allows you to monitor a digital input’s state—and use a change in state to initiate an action through an output, if desired—without triggering an alarm. Events are always Unlatched.

You may also specify a time delay before the AC4 responds to an alarm or event.

Use the steps following Table 13 to change the default settings for any digital input.
