Prepare to Activate

Before attempting to activate your ADT alarm system you will need to prepare the unit by making sure all sensors are secure and powered. You should also make sure that your control panel is connected to your router and receive a connection. Once you have prepared the system for activation, you can proceed to the next steps.

Gather Necessary Tools

When preparing to activate your ADT alarm system without monitoring, there are a few tools you will need to have on hand. The first is the ADT control panel itself. This is usually a wired device that requires connection to the house’s electrical system and communication wiring for the PIR (Passive Infra-Red) sensors. You will also need an electrical screwdriver or drill with Phillips head bit, an Ethernet cable and a network router.

Before you begin, make sure all of these items are present, as well as any instruction manuals that came with the alarm system. If not, contact ADT customer care in order to acquire them. Once all necessary materials are accounted for and ready to go, you can proceed with activating your home security system:
1. Install the control panel and mount it in a central location within your home – typically near the main door or stairs.
2. Run an Ethernet cable between your control panel and your router – Use an Ethernet cable for contact with the internet module for external access via smartphones or web browsers.
3. Connect PIR (Passive Infra-Red) sensors throughout your home – These allow you to create zones which trigger notifications when breached.
4. Test each sensor by walking through its zone – Check that its light flashes green when triggered before moving on to other sensors in other areas of your house or property..
5. Return to the control panel and initiate testing mode – Ensure all connected sensors trigger as they should before finalizing initialization of the alarm system

Read the Owner’s Manual

Reading the owner’s manual of your ADT alarm system is an important first step before attempting to activate your alarm system without monitoring. This manual will provide detailed instructions specific to the model and brand of equipment you purchased. If you don’t have a copy, contact ADT customer service and they will be happy to send you one. It’s important that you understand the commands and programming sequences used by your system before attempting to activate it without monitoring.

Your user manual should include detailed directions for arming, disarming, testing, activating, bypassing and programming various features. It is important that you complete each step in order as detailed in the manual in order for the alarm system to properly detect threats or signal an alarm if one occurs. Be sure to carefully read the entire document and take notes if needed so that you can safely manage all security settings on your home or business property. Once familiar with these instructions, follow each one diligently in order to activate your ADT alarm system without monitoring.

Activate the System

Activating your ADT alarm system without monitoring is easy to do, and there are a few simple steps you need to take to get it up and running. With a few tools and the right instructions, you’ll be able to get your system activated and ready to go. Let’s talk about the basic steps you need to take to activate your ADT alarm system without monitoring.

Connect the Control Panel

Once the control panel is mounted in the desired location and all of the wiring and accessories have been installed as instructed, it will require activation with a battery backup. This procedure will ensure that your system automatically defaults to the “off” position when it is first installed.

To activate your control panel:

1. Make sure the power is turned off to your system for safety purposes.
2. Insert a 9V battery into the appropriate jack within your control panel, or insert four AA or AAA batteries depending on which type you are using.
3.Connect one end of an adapter plug into the AC power supply terminal on your control panel and plug in to an electrical outlet at least 3 feet away from any showers, bathtubs, or drains. (The transmitter must be 1/2 mile away from any other transmitter)
4.Carefully replace any access covers removed during installation then turn on the main power switch for the system by flipping it to the “on” position and verify that all programming is correct.

Connect the Keypad

Now that you have your power, communicator and phone line properly installed, you can begin activating the system with your keypad. Your keypad should have come programmed with a unique, four-digit installer code. Enter this number into the keypad.

It is important to note that this code is not the same as your master user code, but you will need it to access the programming menus in order to set up your system. Once accepted, enter in a master user code of your choice, which should be five or six digits long to make sure someone can’t guess it easily. Then set any additional entry/exit delay time for an alarm system (this is how long it takes for an alarm to activate after a door or window has been opened). The default is typically 30 seconds.

With these steps completed, the final step is learning how to arm and disarm your system from the keypad and from remote devices like an ADT Pulse app on a smart device such as a smartphone or tablet computer. With that knowledge now acquired, your ADT protocol for activating your security system is complete!

Connect the Sensors

Now you have your alarm system, it is time to connect the sensors. Follow these steps to make sure that all the security pieces are connected properly:
1. Start by labeling each of your individual sensor according to the location in which it’s placed. This process will help you when connecting each one so you will have full coverage throughout the house or building.
2. Read carefully through each sensor’s user manual and locate where they need to be placed in order to provide optimal alert coverage. Place them in the predetermined locations according to your model’s specifications and make note of where everything has been installed for future reference.
3. Once your sensors are mounted and connected, check whether any wires require being hidden or run behind walls or beneath carpets for added security measures where necessary. You don’t want easy access for anyone trying to tamper with your alarm system!
4. Finally, test out all of your newly-installed sensors individually to ensure that everything is working properly before continuing with activation of the system itself.

Test the System

Testing your ADT alarm system before actually activating it is the best way to ensure that there are no issues with the installation and setup. There are several ways to test the system, including opening and closing doors, turning off and on lights, and checking the console for any error messages. Let’s get started by testing the system.

Activate the System

Activating your ADT alarm system is simple and should only take a few minutes. Follow the steps below to ensure that your system functions properly even without an active monitoring plan.

1. Open the ADT Control App on your device, or visit “” if you’re using a computer.

2. Log in using your account details (username and password).

3. Locate the “Security System” section of the app or website, and then select “Activate Alarm System” from the dropdown list to begin setup.

4. Enter the 4-digit code for your system into the prompted field, then click “Continue” to move forward with activation instructions for specific devices (a smoke detector, door/window sensors, etc.) connected to your ADT system – it may include pairing devices with an appropriate sensor hub or setting up remote access controls over WiFi or Bluetooth connections depending on your model and setup needs.

5. When all necessary aspects of activation are complete, you should get a confirmation message within the app/website indicating that everything has been properly activated-you’re now ready to use all features without requiring active monitoring services!

Test the Sensors

It’s important to know that testing the sensors is an essential part of your system activation process. Test all configured sensors to ensure that they are working properly. This will help ensure that your alarm system activates when needed and reduces the possibility of false alarms caused by faulty sensors.

Part of this step is testing the motions sensors. These should be tested by walking at different speeds in front of the sensors to make sure it is reacting appropriately. When walk past slowly, make sure you see the LED light up green or hear a chirp sound, telling you that it has detected motion correctly. You should also test any window and door contacts with a multimeter before setting them so they detect correctly when monitored. Finally, make sure you test out any smoke detectors and check their current battery level before installing them in their respective locations around your home.

Test the Keypad

Before connecting your ADT alarm system to monitoring, it’s important that you test the keypad and make sure all devices have been installed correctly. Start by entering your code and press the “!” pound button twice. Then the keypad will beep three times, followed by a pause, then a single beep – indicating that you have successfully started system testing.

Next, press any lighted buttons on the control panel to make sure they respond properly. Pressing different buttons will cause lights corresponding to those buttons to flash within three seconds of pressing each button. Additionally, if your system has two numerical codes it is important to try both as well as making sure both codes turn off the alarm in case one ever fails in future.

Check all window and door contacts for proper adjustment and sensitivity. To do this securely close each door or window with its magnet until it produces an audible click sound that indicates that it is secure. Be sure to open and close all windows or doors twice during testing so you can confirm functions are operating correctly with both opening/closing motions of each sensor device.

Finally, press your “away” button until you hear two beeps come from the keypad (this means motion detectors are also working). After hearing these two beeps enter your code again, followed by pressing “1” on the keypad this will activate the alarm momentarily (about 8 seconds). After 8 seconds have passed press “off” on your keypad to deactivate the alarm – successful deactivation indicates your motion detectors are working properly as well!


If you are having difficulties activating your ADT alarm system without monitoring, there are a few troubleshooting steps you can take to resolve the issue. From checking the batteries to ensuring the sensors are properly connected, there are many potential causes of an ADT alarm system that won’t activate. Let’s go over some potential solutions and troubleshooting steps you can take to get your system up and running.

Check the Batteries

Check the batteries located in your main control panel. Replace them with new batteries if necessary. Batteries can cause the ADT alarm system to fault, triggering the monitoring system and sending multiple false alarms. If a low battery fault is detected, you will be notified. The trouble light will turn on and you will hear frequent chirps coming from the control panel every 10 seconds indicating that a battery needs to be replaced. Use only AAA or AA alkaline batteries as all other types of battery can cause additional problems with your system. Replacing batteries in an ADT alarm is simple: locate the control panel, open it with a flathead screwdriver (depending on your model), and remove the old batteries. Put the new ones in place, close it and wait to see if all sensors work properly after a couple of minutes.

Verify the Connections

Verifying the connections between your alarm system components is the first step in getting your ADT alarm system up and running. Make sure that each console is firmly plugged into a power source, as well as an internet connection. If you are using a wireless system, make sure that all modules are within range of an available wireless network. Additionally, check all connections between components to ensure that each cord is secure and has not become loose or disconnected. If any of the connections appear to be damaged or compromised, it may be necessary to replace them before proceeding with activation. Once you’ve verified the physical connections, check for any visible signs of failure on any of your alarms devices such as LCD screen displays that may signify a need for repair or replacement.

Check the System Settings

To troubleshoot your ADT alarm system, the first step is to check the system settings. Verify that the active zones are in line with what you expect them to be and check whether any malfunctioning devices may be preventing successful activation. If there is an issue with a device or zone, make sure that it is addressed before attempting to activate your system. Also, ensure that all internal components such as sensors and motion detectors are properly connected and working correctly by running a diagnostic test with your central control panel. Additionally, review the main control panel’s settings to make sure they are configured according to your specific preferences. Once you have confirmed that all of the components of the system are functioning properly and that the correct settings are enabled, it’s time to move on to activating your ADT alarm system without monitoring.
