This feature lets you set Filter Limits for the selected Sensor/Transmitter.

Example 1:If, say, a Sensor/Transmitter is located in or near to an electrical switch panel, which can be very noisy electrically, occasional interference may occur on the radio link, which would be seen on the graph as a large spike in the data.
Sensor Filters are designed to remove such interference.
Example 2:If, say, a Sensor/Transmitter is monitoring temperature and the expected range for this application is -10°C to +50°C, a Filter could be set at say -40°C for the Minimum Value and +80°C for the Maximum Value and any readings seen above or below these values would be rejected.
Caution:Filters should only be used in exceptional circumstances.

Edit Mode Window


By default, the Sensor and Zone editing/configuration window for the Zone at the top of the left-hand menu is displayed.

To display another Zone's Edit Mode window, click on the entry for the required Zone in the left-hand menu. For an example, see Figure 1019 below:

ii.In the left-hand list, click on the required Sensor's icon Sensor Icon.


In table in the Zone's Edit Mode window, click on the required Sensor's name in the Sensor Name column. See Figure 1021 below:

Figure 1021

Select Sensor Name Edit Mode Table

The Edit Mode window for the selected Sensor is displayed.  See Figure 1022 below:

Edit Mode Window for Sensor

3.Click on FILTERS to display the Filters pane for the selected Sensor/Transmitter.

Tabs are displayed for each of the selected Sensor's channels. See Figure 1023 below:

Sensor Filters Window

Sensor Filter Window 2

4.To activate each channel's Filters, enter the required Minimum and Maximum values into the Min Value: and Max Value: dialog boxes.

For Temperature Filters, the values should be whole numbers within the range 50 for the Maximum value and -40 for the Minimum value.

5.Click on Save. See Figure 1023 above.

This will save the Filter values for the currently selected Sensor/Transmitter.

The following message will be displayed and you will be  returned to the GENERAL INFORMATION pane. See 1024 below:

For dual or triple Channel Sensor/Transmitters, repeat the above process for the other channels.

Caution: Setting Filters will cause data to be rejected above and below the Filter's limits.
Check that any Filter limits set are above and below the expected ranges.
