How to walk test the WXS and BXS sensors

28 February 2022
The BXS (curtain) and WXS (180-degree) sensors offer independent left and right detection areas and precise detection zones on each side can be set to adapt to the property’s features and areas where coverage is needed. Performing a walk test is a crucial step to validate the detection areas set.

Part of the Shield series, both the BXS and WXS sensors feature independent left and right detection settings. The detection range can be adjusted ad certain areas can be masked to adapt to the site’s layout. To validate the set detection areas, it is important to perform a walk test.

WX Series

The WXS provide a 12 metre, 180-degree detection area and first you should begin walking around in the detection area (default settings), noting that the sensor is triggering.


When you have customised the detection range, close the cover of the sensor to start the automatic walk test mode, which will give you up to three minutes to walk the detection area again. The sensor’s LED will blink when you are detected and stop blinking if you aren’t, allowing you to validate the customised detection area.

The BXS series

The BXS is an outdoor curtain detector providing up to 12m detection range on the left and on the right. In a similar way to the WXS, you can create a customised detection area based on your requirements. The BXS sensor when new and out of the box will be pre-set to its fullest detection: 12m each side.


Once you have set your BXS sensor to the desired specifications, close the cover to automatically start the walk test mode. You should walk down the left side of the detector and right side of the detector, the red LED blinking on the left or right lens will indicate that you are being detected. If the LED stays off you are not detected. You can add accuracy by measuring out your range, so if you have set detection to 6m, you should not trigger any alarms beyond that point.

If you are not entirely satisfied by the detection settings you can repeat the process described above.
