1.11 Typical Sequence
Figure 4 shows a typical sequence of how the Universal Monitor functions after detecting a change in
a monitored unit or area. Many responses depend on configuration settings. This example shows what
happens when an analog sensor input reaches a high setpoint—assuming the input is defined as
alarmable and is set up to trigger a response in an output—and when the condition returns to normal.
