Door/Window Sensor—Tamper Error

To determine which door/window sensor you have, click on the image of your panel below for instructions on how to securely replace the sensor cover.


Tips to resolve the cover tamper issue:

    • A tamper error occurs when the sensor reads the panel's cover is not attached properly
    • Ensure batteries fit within their intended compartment
    • Ensure the cover is replaced snugly into its designed casing
    • Ensure any fasteners, such as screws or tabs, are tightened or securely locked into place
    • All arrows (or alignment markers) between the sensor and magnet need to be realigned and the gap should be no more than 1/4 of an inch (about the width of a pencil)
