You may need to remove a zone from your ADT alarm system for a number of reasons. Maybe you’re moving and don’t need that zone anymore, or maybe you added a new sensor and now have too many zones. Whatever the reason, removing a zone from your ADT alarm system is a pretty easy process.


Removing a zone from your ADT alarm system requires a few steps of preparation. Before you can remove a zone, you need to know the exact location of the zone and make sure that all the wiring and sensors are disconnected. You also need to make sure that you have the right tools and materials available to complete the process safely and securely. Once the preparation is done, you can move on to the removing process.

Gather the necessary tools

Prior to starting the zone removal process, it is important to ensure that you have all of the necessary tools on hand. Some of the items that you may need include a standard Phillips head screwdriver, a ladder (if necessary to reach the control panel), a pair of wire cutters, and replacement batteries if your system requires them. Additionally, some systems may require special tools such as two-wire terminals or screwdrivers with a finer tip. Make sure you check your system’s manual before beginning in order to ensure that you have all of the right tools for the job.

Read the user manual

Before attempting to remove a zone from your ADT alarm system, it is important that you thoroughly read the user manual included with your system. While each ADT alarm system is unique and the exact process necessary to make changes may vary across models, the majority of systems will require you to enter codes into their keypad. Several different codes may be needed in order to properly remove a zone.

In order to access the keypad, locate the LED at the far right of your control panel. This LED typically features an instruction manual contained inside of it which indicates how to access and utilize your control panel’s programming menu. Once you access this menu, you will be able to make adjustments such as adding or removing zones from your system. It is important that only authorized personnel manage these changes as incorrect configurations can compromise the security of your alarm system.

Additionally, some ADT alarm systems feature an online management account where customers can manage their settings from any computer or mobile device with internet access. In order to access this online management portal, users should consult their user manual for instructions on how to create a login credential and activate their account; once an account is created, customers can log in remotely and customize settings for their alarm system including changing or disabling specific zones within their location’s security perimeter.

Disarm the System

The first thing you’ll need to do to remove a zone from your ADT alarm system is to disarm the system. You can do this by entering your system’s access code. Once the system is disarmed, you can proceed to the next step to remove the zone. This guide will outline all the steps you need to take in order to successfully remove a zone from your ADT alarm system.

Enter your code

Before you can disarm your ADT Alarm System, you must first enter your four-digit security code. To do this, press the “Arm” button on the main panel, which will bring up a keypad. Using the number pad, enter your security code, then press and hold the “Disarm” button until the system reads “Code Accepted”. Your system is now disarmed and ready for zone removal.

Press the Disarm button

To disarm the alarm on your ADT security system, first locate the keypad and press the “Disarm” button. You will be required to enter your four-digit security code for access. Once entered correctly, the control panel should display as “Disarmed” or a similar message. It is important to remember that after you disarm your system, any area sensors or motion detectors associated with the system remain active until you manually disable them. You can do this by pressing and holding the corresponding zone button on your keypad until it flashes green. This indicates that this particular sensor has been disabled and can no longer set off the alarm if triggered while disarmed. Once all zone buttons have flashed green, you may securely leave your premise without triggering any alarms from these areas of your home or business.

Remove the Zone from the System

Removing a zone from your ADT alarm system is a simple process that doesn’t require any specialized tools or expertise. With the proper steps and a little patience, you can easily remove a zone from your system and keep your home or business safe and secure. Let’s take a look at how to remove a zone from your ADT alarm system.

Find the zone you want to remove

If you want to remove a zone from your ADT alarm system, the first step is to find the zone you want to remove. You can either use your user manual or the owner’s guide for your system to find it. The user manual should provide detailed instructions on how to locate the zone you want to remove.

Once you have located the specific zone that you would like to remove, you will need to determine what type of system it is: wired or wireless. For wired systems, disconnect the wires for that specific zone from the alarm panel and make sure all connections are secure. For wireless systems, disengage or disable the particular sensor from its control panel by pressing the Test/Bypass button and then following any additional instructions indicated in your user manual.

Once all wiring and disabling processes have been completed, you should test out any changes made before logging out of your security network as a precaution. To further ensure that no malfunctions occur after removing a zone, it is important that users regularly test their alarm systems using their assigned testing procedure as recommended in their user manual.

Press the Remove button

To remove a zone from your ADT alarm system, you must first access the security panel. To do this, enter your custom user code. Then press the Remove button, which is located at the bottom of the screen.

Once you’ve successfully accessed the panel, you can now delete any zones that need to be removed. To delete a particular zone, use the navigation buttons to scroll through each one and find the appropriate one that needs to be deleted. When the desired zone appears, press and hold down on both red ‘Trouble’ buttons at its top right-hand corner until it disappears from your system.

Once you have thus eliminated all unwanted zones from your system and confirmed they have been removed successfully by double-checking with each individual alarm package connected to your unit, it’s important to check that all other system components are still working correctly: verify that each protection sensor and monitor is still operational online as well as testing them manually with an active test signal transmission. Finally, update your user code for added security before exiting out of the security panel menu tab.

Reconfigure the System

Removing a zone from your ADT alarm system is easy with the right information. Before we get started, you need to gather some key information about your system, including the brand, model number, and serial number so that you can properly reconfigure the system. Once you have all of the necessary information, you can begin the process of removing a zone from your ADT alarm system.

Enter the new code

Before you can remove a zone from your ADT alarm system, you will need to change the system entry code. This step is important because it prevents unauthorized users from accessing the system and making changes, such as deleting a zone. Start by inserting the new code into your keypad and pressing “Enter.” The code should be at least four digits (some systems require up to 12). If this is the first time entering this access code, enter it twice to confirm. Once you have entered your new code, press the “#” key on the keypad to exit programming mode before moving on to reconfigure the zone in question.

Reset the system

Once you have identified the zone that you want to remove from the ADT alarm system, you will need to reset the system. Resetting your alarm system helps ensure that old settings are completely wiped and replaced with factory settings, making room for a fresh start. To reset your security system, press and hold down on your ADT control panel’s “OK” or “Status” key for 15 seconds. All lights on the panel will turn off during this process and will eventually come back online when it is finished. After this procedure is complete, the system has been reset and is ready to reconfigure.

Test the System

Before proceeding with the process of removing a Zone from your ADT Alarm System, it is important to test the existing system. This step ensures that all existing components and wiring are in good working order. The testing process should include a series of tests on the keypad, sensors, and control panel to verify that the system is functioning properly. Once the testing is complete, you can proceed with removing the Zone.

Trigger the alarm

Before you can remove a zone from the ADT alarm system, you must first trigger the alarm. Doing so will ensure that the zones installed and enabled on your system are configured correctly. To trigger the alarm, open the door or window connected to one of your existing zones, wait a few seconds, and then press your ADT Master Code on any keypad installed in your home. When you enter your code into a keypad, it should cause an audible siren within 15-20 seconds to be activated. Once the alarm has been triggered, it is time to begin testing and removing the zone connected to it.

Check the status of the system

It’s important to begin by checking the status of the system. Before adding or removing a zone, you will need to access your ADT alarm system. To do that, you’ll need to log in with your username and password. After doing that, locate the ‘User Code Management’ section of the page and make sure your code is still active, if not you will need reset it before going any further.

Next, decide which zones you’d like to modify from your current system so that you can determine what type of device or what type of wiring may be necessary. You can also check any other features associated with the zones being modified such as Zone Sensitivity adjustments available for each zone or a Fire Verification feature for Heat and Smoke Detectors within protective zones. Take some time to research possible device options and identify any installation-specific requirements before adding or removing a zone from your ADT Alarm System.
