Frequently Asked Questions
You have questions, we’ve got you covered
What is this product?
Door/Window Sensor Spacers offset deep door or window molding when setting up your Door/Window Sensors. The spacers line up the sensor and magnet within range (½ inch) so the device can function properly. The thin plastic pieces fit under the sensor and/or magnet. You can stack multiple spacers together to achieve the height needed for your molding.
How do I install it?
The spacers should be installed using the pre-applied double-sided tape and/or included screws. Visit our support article for step-by-step instructions.
Are sensor spacers included ADT Blu security systems or sold separately?
Door/Window Sensor Spacers are sold separately. Each pack of 2 includes 2 spacers for the sensor and 2 spacers for the magnet (4 total pieces), pre-applied double-sided tape, and screws.
