"alarmed" State
This state means a discrete (on/off) sensor is in the "abnormal" state.
Usually for a contact closure sensor, the meaning of this state varies
based on the sensor's normal state setting.

If the normal state is set to Normally Closed, the
alarmed
state
means the contact closure switch is open.

If the normal state is set to Normally Open, the
alarmed
state means
the contact closure switch is closed.
For a Raritan's floor water sensor, the normal state must be set to
Normally Closed, which means no water is detected. The
alarmed
state
indicates that the presence of water is detected.
Note: See Environmental Sensors Guide for information on setting the
normal state or dip switch. This guide can be downloaded from the
Raritan website's
PX2 Support Files page
( ).
Tip: A contact closure sensor's LED is lit after entering the
alarmed
state.
Determine which contact closure switch is in the "abnormal" status
according to the corresponding LED.
"below lower critical" State
This state means a numeric sensor's reading is below the lower critical
threshold as indicated below:
Reading < Lower Critical Threshold
"below lower warning" State
This state means a numeric sensor's reading is below the lower warning
threshold as indicated below:
Lower Critical Threshold <= Reading < Lower Warning Threshold
Note: The symbol <= means smaller than (<) or equal to (=).
"above upper warning" State
This state means a numeric sensor's reading is above the upper warning
threshold as indicated below:
Upper Warning Threshold <= Reading < Upper Critical Threshold
Note: The symbol <= means smaller than (<) or equal to (=).
