Why is my Entry Sensor shown as open?
If you are consistently seeing a warning that one of your Entry Sensors is open, despite all of your doors and windows being closed, one of the following items is likely the cause:
Your Entry Sensor is too far away from its corresponding magnet piece.
Your Entry Sensor (or its corresponding magnet) is placed on a metallic surface.
First, double-check that the printed sensor number matches with the number reported in the warning. If the warning only shows a name, you can access the individual sensor's settings through the Keypad to find the sensor number. Next, make sure that all of your doors and windows are closed. If the door/window where this issue is occurring is metal, placing a buffer between the magnet and the metallic surface may help (such as a couple of extra adhesive strips).
