Key Specs for This ADT Bundle

3 Spacer Thicknesses: 1", 1/2", and 1/4"

The kit includes three distinct spacer heights to handle various door and window frame gaps. You can select the 1-inch riser for deep frames, the 1/2-inch option for standard gaps, or the 1/4-inch size for tight spaces with limited clearance. This variety ensures your ADT contact sensor and magnet remain within the optimal detection range, regardless of the installation depth. It eliminates the need to guess or buy separate single sizes for different entry points in your home.

24 Magnet Adhesives

This bundle provides twenty-four adhesive pads specifically designed for the magnet portion of ADT contact sensors. These pads allow you to securely attach the magnet to your door or window frame without tools. The pre-cut design simplifies the installation process, making it suitable for DIY enthusiasts and homeowners. Having this quantity ensures you have enough replacements for multiple sensors throughout your entire property, maintaining consistent alignment and detection reliability for your security system.

12 ADT Contact Sensor Risers

The package contains twelve sensor risers, which are the spacers placed behind the main sensor body. These risers push the sensor back to create the necessary gap for the magnet. This count supports a whole-home installation, covering various entry points like doors and windows. By using these risers, you ensure the sensor remains properly aligned with the magnet, preventing false alarms or missed detections caused by frames that are too deep or shallow for the sensor to sit flush.

3M PE Foam Adhesive

Each spacer comes with pre-cut 3M PE Foam adhesive for secure, tool-free installation. This premium adhesive ensures a strong bond to various surfaces, including wood, vinyl, or metal frames. The peel-and-stick application makes it easy to install without mess or specialized tools. It also offers no-residue removal, allowing you to change positions or remove the spacers later without damaging your door or window frames. This feature is crucial for renters or those who may need to adjust sensor placements.

ADT Bundle Design and Build

The listing describes this kit as a complete alignment solution for ADT systems. It includes twelve sensor risers and twenty-four adhesive pads. The spacers come in three distinct thicknesses: one inch, one-half inch, and one-quarter inch. You can choose the one-inch riser for deep frames where the gap is large. The one-half inch option suits standard door or window gaps. The one-quarter inch spacer handles tight spaces with limited clearance. This variety allows you to maintain the optimal detection range for your contact sensors regardless of frame depth. According to the listing, the kit is designed for ADT Blue Contact Sensors, ADT Door Sensors, and ADT Window Sensors. The color is listed as ADT. This suggests the components are intended to match the aesthetic of ADT branded equipment. The layout is a variety pack. You receive four of each spacer size. This distribution covers multiple installation points in a whole-home setup without needing separate orders. The build focuses on functional alignment rather than decorative finish. The goal is precise positioning of the magnet relative to the contact device. Proper alignment ensures the sensor triggers correctly when the door or window opens. The design prioritizes utility over style. You get the specific dimensions needed to bridge the gap between the sensor body and the frame. This ensures reliable operation of your security system. The kit does not include the sensors themselves. It only provides the spacing and adhesive materials needed for installation. This makes it a practical addition for upgrading or replacing existing setups. The design supports both professional installers and DIY users who need consistent spacing across multiple entry points.

Setup And Daily Use Guide

Setting up this bundle requires no tools. The listing states that each spacer arrives with pre-cut 3M PE Foam Adhesive. You simply peel the backing and stick the spacer to the sensor or magnet. This tool-free method allows for quick adjustments. The adhesive is designed for secure attachment. It also offers no-residue removal, which helps when you need to reposition a sensor or replace a spacer later.

This kit is built for ADT systems. It works with ADT Blue Contact Sensors, ADT Door Sensors, and ADT Window Sensors. The goal is to maintain the optimal detection range. If your sensor is too far from its magnet, the system may fail to trigger. These spacers bridge that gap. You choose the thickness based on your frame depth. Use the 1-inch riser for deep frames. The 1/2-inch option fits standard gaps. The 1/4-inch spacer handles tight spaces with limited clearance.

In daily use, you place the correct spacer between the sensor and the magnet. This ensures they align properly. The bundle includes 24 adhesive pads for this purpose. You do not need separate glue or mounting hardware. The kit supports whole-home installations. It is suitable for homeowners managing multiple sensors. It also serves security professionals who need a variety of sizes on hand. The process remains consistent across all ADT contact devices. You ensure a reliable connection by keeping the sensor and magnet at the correct distance.

What You Need Before Buying

You need to verify your specific ADT sensor models before purchasing. This bundle is designed for ADT Blue Contact Sensors, ADT Door Sensors, and ADT Window Sensors. Using it with other brands may not provide the correct alignment. The listing confirms that contact devices and magnets are not included. You must already own these sensors to use the spacers effectively. Upkeep is minimal because the 3M PE Foam Adhesive is designed for secure attachment without tools. You can remove the adhesive without residue if you need to adjust the spacing later. This product fits into the broader home surveillance ecosystem by maintaining optimal detection ranges. Proper alignment ensures your security system functions correctly. If you have multiple doors and windows, this variety pack helps maintain consistent performance across your entire ADT setup. It is a practical addition for homeowners who want to ensure their existing hardware remains aligned and effective without needing professional installation services.

Check before you buy

• Verify your sensors are ADT Blue, Door, or Window models.
• Confirm you already own the contact devices and magnets.
• Check frame gaps to choose the right spacer thickness.
• Ensure you need tool-free installation for your project.
