How to Open ADT Window Sensor?

Published in ADT Security Systems 3 mins read

Based on the provided information, opening an ADT window sensor seems to be related to accessing settings or replacing batteries, rather than simply opening the device in the conventional sense. The steps provided refer to accessing settings online, likely for management.

Here's a breakdown based on the given references:

  • Accessing System Management (Likely NOT opening the physical sensor):

    1. Go to my att.com.
    2. Select "My Alarm" from the dashboard.
    3. Select "System Management" from the menu that appears.

The video referenced, "How to Replace Your ADT Door Window Sensor Batteries," suggests physical interaction. Unfortunately, the video excerpt provides no specific instructions on how to open the sensor itself. Without more information, assuming you are trying to replace batteries, here's a general approach (though always consult your specific ADT sensor's manual or ADT support for definitive instructions):

  • Replacing Batteries (General Approach - Consult Your Manual First!):

    1. Identify the Battery Compartment: Look for a seam or small indentation on the sensor housing. The battery compartment is usually located on the back or side of the sensor.
    2. Opening Mechanism: The sensor might have a small latch, a slide-off cover, or require a small screwdriver (Phillips head or flathead) to remove a screw securing the cover. Be very gentle to avoid damaging the sensor.
    3. Open the Sensor Carefully: Gently pry or slide the cover open, being careful not to damage any internal components.
    4. Replace the Battery: Note the battery type (e.g., CR2032, AAA) and its orientation (+/-). Remove the old battery and insert the new one correctly.
    5. Close the Sensor: Reattach the cover, ensuring it's securely closed.
    6. Test the Sensor: Test the sensor by opening and closing the window to ensure it's communicating with the ADT system.

Important Considerations:

  • ADT System Specifics: ADT systems vary. The exact method for opening the sensor will depend on the specific model you have.
  • Tamper Alerts: Opening the sensor might trigger a tamper alert on your ADT system. You may need to disarm the system before proceeding (check your ADT documentation).
  • Professional Assistance: If you're unsure about any step, it's best to contact ADT support or a qualified technician for assistance.
