Table 15 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 Normally Closed, and specify it as alarm- able 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 AC8 responds to an alarm or event.

Use the steps following Table 15 to change the default settings for any digital input.
