Managed sensor states:
In the following table, "R" represents any numeric sensor's reading. The symbol <= means "less than" or "equal to."
State
Description
normal
•
For numeric sensors, it means the readings are within the normal range.
•
For state sensors, it means they enter the normal state.
below lower critical
"R" < Lower Critical threshold
below lower warning
Lower Critical threshold <= "R" < Lower Warning threshold
above upper warning
Upper Warning threshold < "R" <= Upper Critical threshold
above upper critical
Upper Critical threshold < "R"
alarmed
The state sensor enters the abnormal state.
unavailable

Managed dry contact states:
State
Description
on
The dry contact is turned on.
off
The dry contact is turned off.
unavailable
•
The communication with the managed dry contact is lost.
