Advanced View: Defining Thresholds

The appliance uses analog sensors and state sensors. Analog sensors report sensor readings as a value within a range of potential values defined by a minimum and maximum value, such as temperature or humidity readings. If the value reported by a sensor exceeds the specified threshold, an alert condition is reported. State sensors report sensor readings as one of two mutually exclusive states, such as a door being open or closed. A state change reported by a sensor generates an alert condition.

Defining Analog Thresholds

To define a threshold:

1.Double-click the Camera Pods, Sensor Pods, or Scanned Devices icon.

2.Click Sensors... to open the Sensor Configuration window. You may also right-click a sensor in the Sensor Data Pane and click Configure Pod... .

3.To define a threshold, select a sensor from the Sensors list. Defined thresholds for the sensor, if any, appear in the Thresholds list.

4.Click Add... to open the Select Threshold Type window.

5.Select the threshold to define and click OK. The Add Threshold window opens.

6.Type a name for the threshold in Threshold name.

7.Specify threshold settings in the Basic tab:

a.For an Above Value for Time Threshold, enter the highest acceptable value for the selected sensor in the Maximum field. In Time Allowed Above Maximum, enter the number of seconds that the reported value can exceed the value specified in the Maximum field before an alert condition is generated.

b.For a Below Value for Time Threshold, enter the highest acceptable value for the selected sensor in the Minimum field. In Time Allowed Below Minimum, enter the number of seconds that the reported value can fall below the value specified in the Minimum field before an alert condition is generated.

c.For a Maximum Value Threshold, enter the highest acceptable value for the selected sensor in the Maximum field.

d.For a Minimum Value Threshold, enter the lowest acceptable value for the selected sensor in the Minimum field.

e.For a Range Threshold, enter the maximum and minimum values for the selected sensor.

f.For a Rate of Decrease Threshold, enter the highest acceptable change value for the selected sensor in the Maximum Decrease field. Enter the number of seconds that defines the unacceptable change period in the Time Period field.

g.For a Rate of Increase Threshold, type in the Maximum Increase field the highest acceptable change value for the selected sensor. Type in the Time Period field the number of seconds that defines the unacceptable change period.

h.For a Temperature Proximity Threshold (Dew Point sensors only), enter a number of degrees. If the calculated Dew Point is ever within that many degrees of the current temperature, an alert will be generated.
