Supervised Alarm Input Wiring
Unsupervised Alarms
When an alarm is configured as an unsupervised alarm, the SP04-140 only triggers an alarm when the normal alarm state (open or closed)
changes.
Figure 16 illustrates the alarm and no alarm conditions of an unsupervised alarm input. A normally closed alarm input can be defeated with a
bypass. A normally open input can be defeated with a cut.
