Understanding Your ADT Motion Sensor

Before you begin, it's crucial to identify the specific model of your ADT motion sensor. ADT offers various models, and the opening procedure might slightly differ. Locate the model number on the back of the sensor for precise instructions. Generally, however, the process is similar across most models. Always refer to your ADT system's documentation or contact ADT support if you are unsure about any step.

Tools You Will Need

Before attempting to open your ADT motion sensor, gather the necessary tools. You'll likely need:

• A small Phillips head screwdriver: This is essential for removing screws.
• A flathead screwdriver (optional): May be needed to gently pry open certain components if screws aren't readily visible. Use caution to avoid scratching the sensor's surface.
• A new battery (if needed): Check your sensor's documentation to find the correct battery type.

Step-by-Step Guide to Opening Your ADT Motion Sensor

Important Safety Note: Always ensure your ADT system is armed before proceeding. This step helps prevent accidental triggering of the alarm during the process.

Step 1: Locate the Screws

Carefully examine your ADT motion sensor. Most models have small screws located on the back or bottom. These screws secure the sensor's cover. Sometimes they are hidden under a small cover that needs to be removed first.

Step 2: Remove the Screws

Use your Phillips head screwdriver to carefully remove the screws. Avoid stripping the screw heads by applying steady, even pressure. If the screws are difficult to remove, try using a bit of penetrating oil.

Step 3: Separate the Cover from the Sensor Body

Once the screws are removed, gently separate the cover from the main sensor body. Depending on your model, this may involve simply lifting the cover or carefully prying it open using a flathead screwdriver (if needed). Always apply minimal pressure to avoid breaking any clips or components.

Step 4: Accessing the Internal Components

With the cover removed, you'll have access to the internal components, including the battery compartment. If you're replacing the battery, carefully remove the old battery and insert the new one, ensuring correct polarity (+ and -).

Step 5: Reassembly

Once you've completed your task (battery replacement, cleaning, or troubleshooting), carefully reassemble the sensor. Align the cover with the sensor body and gently push it into place. Replace the screws, ensuring they are securely tightened.

Troubleshooting Tips:

• Sensor not working: Check the battery first, then ensure proper alignment of internal components. If problems persist, contact ADT support.
• False alarms: Check for obstructions in the sensor's field of view. Ensure that pets or other moving objects are not triggering the sensor unnecessarily. Clean the lens to remove any dust or debris.

Maintaining Your ADT Motion Sensor

Regular maintenance ensures optimal performance. This includes:

• Battery Replacement: Replace batteries as needed, following the manufacturer's recommendations.
• Cleaning: Periodically clean the sensor lens with a soft cloth to remove dust and debris.
• Testing: Regularly test your motion sensor to ensure it's functioning correctly. Your ADT app may have a testing feature.

By following these steps, you can safely open and maintain your ADT motion sensor, ensuring your home security system remains effective. Remember to always consult your ADT documentation or contact their support team if you have any questions or concerns.
