Read the instruction manual

It is important to read the instruction manual carefully before beginning your installation. The manual typically contains useful information regarding the proper placement of various components and warnings about any potential hazards. Not all systems are designed the same; make sure you thoroughly understand the instruction manual and consult with an ADT professional if necessary.

The first step when installing your home security system is to determine where the sensors and other components will be placed. This step is essential for successfully activating motion sensors, alarms, and notifications in a timely manner. It’s important to choose locations within sight lines of entryways or windows in order to maximize effectiveness. When considering placement, also identify potential risks such as overly bright lights or direct sunlight that could set off motion detectors, as well as places where children or pets might accidentally trip an alarm accidentally.

In some households, it may be necessary to drill into walls in order to install alarm panels or sensors so make sure you have all of the necessary tools ready before you start building your system. Additionally, many systems require a working Wi-Fi network- double check that it is functioning correctly prior to installation so that any settings can be adjusted with ease afterwards. Once the system has been correctly hooked up, you can configure alarms or automatic alerts on compatible apps and devices though your user account in anticipation of future safety needs.


Installing an ADT home security system is relatively easy and does not require any prior knowledge of electronics or home security systems. There are a few steps to follow to properly install the system and ensure that everything is set up correctly. This guide will provide you with an overview of the process and outline the key steps such as wiring the sensors, activating the system, and configuring the mobile app.

Mount the control panel

The ADT home security systems are designed to make installation as easy as possible. To help you get started, the control panel is pre-programmed and ready to begin protecting your home right out of the box. Before installing the control panel, please turn off all power to avoid any unnecessary shock or damage. Once complete, mount the control panel near a primary entry point in your home and follow these steps:

1. Carefully review all instructions before proceeding with installation
2. Select an appropriate mounting location that is dry and away from direct sunlight
3. Use the provided screws and fasteners (included with the system) to mount the control panel
4. Ensure that the backplate is secure at every corner and that no wires are exposed
5. Connect the power and telephone line (if applicable) at this time
6. Turn on power at wall switch and check for small green LED light on back of control panel after powering up
7. Test device by entering 6-digit Master Security Code into keypad upon turning on power
8. Calling ADT Customer Service or refer to system User’s Manual before proceeding (if needed)

Connect the control panel to the power source

The ADT home security system requires connection to an electrical outlet and a telephone line. Before connecting the power supply to the control panel, install or connect the systems’ ante-nuisance modules (aRM) to wall sockets in areas that are important to you, such as bedrooms and living spaces. The aRM will detect motion within its range and activate the control panel if motion is detected when armed. After connecting the aRM modules, locate the control panel directly by an easily accessible power source. Plug in both electrical cords of the supplied power adapter into their correct outlets on backside of control panel. Connect one end of flat phone cord into Telephone wall jack. Connect other end of telephone cord into “Phone” outlet on backside of Control Panel. Double check all connections before plugging in ADT Security System’s power adapter into nearby electrical socket; then turn it on according to installation guide instructions.

Install the sensors

Before you begin installing the home security system, you should make sure you have the right tools and materials. You’ll need a screwdriver, drill, tape measure and level. You may also need a hammer, wire cutters and scissors.

You may want to consider having an electrician assist with installation. If necessary, turn off power at the circuit breaker before beginning any wiring changes or modifications.

The sensors must be placed in proper locations to create a secure perimeter around your home. Make sure to read the manufacturer’s instructions for each component before installation so you know where to place it and how it functions. When selecting sensor locations, think like an intruder and determine which views of your home or yard can be accessed easily via doors or windows, attic access points or even vents in the roof or siding.

Once selected, attach each sensor directly onto walls with mounting screws provided by ADT or use double-sided adhesive strips instead of mounting screws if adhesive is specified for that particular model for easier installation in hard-to-reach areas such as window frames and door jams. Sensors should be installed near any entry point that could possibly be used by an intruder to gain access into the house such as windows, doors and attic access points.

Connect the sensors to the control panel

Once the control panel has been mounted or placed in a convenient location, it’s time to connect the sensors to the device. Depending on your security system model, you will need to attach the window and door sensors to the control panel using two-wire leads. Start by following the instructions included in your ADT security kit.

First, insert one end of a two-wire lead (red and black) into each of the corresponding ports on both sides of the connected window or door sensor. Then insert the other end into a numbered terminal found on your control panel according to instructions. Make sure that each sensor is accurately labeled before connecting. Once any sensors are connected, use another two-wire lead to connect any additional accessories such as motion detectors, smoke alarms or external sirens. It is important that all accessories be securely connected and tested before testing your alarm system.


Testing is an important part of the setup when installing an ADT home security system. You need to make sure that all the components are working properly, and the system is set up correctly in order to ensure it is providing the maximum level of protection. This step-by-step guide will show you how to test your system to make sure it is working properly.

Run the system test

The first step in installing an ADT Home Security System is to run the system test. This will ensure that all sensors, contacts, sounders and other components are operating correctly. During this test, you should check that all alarm zones are active, that lights and sirens respond to simulated alarms, and that the control panel is functioning properly.

To begin running the system test:
1. Connect the home security system’s power source according to manufacturer’s instructions.
2. Turn on the system by pressing the ‘Start’ key on your keypad or remote control device.
3. Enter your four-digit entry code provided with your system at installation; make sure it produces a single long beep when you enter it correctly..
4. Test each alarm zone individually by triggering its corresponding signal within a two-second interval of each other; while monitoring the signal output from each detector or contact point within each zone, ensure they correspond to what was triggered and record outcomes for future reference if needed.
5. Verify that siren sounds for at least 1 minute after any signal activation is detected; test both interior sounder and exterior notification device if applicable (i.e., strobe light).
6. Finally, manually activate smoke detectors using a heat source such as a match or small butane torch to set off an alarm (if able). Record results during this step as well and refer back during future diagnostics if necessary .

Set up notifications

Once your ADT home security system is installed, you will want to set up notifications so that you are alerted in the event of an alarm. In order to set up notifications, you need to create a myADT account and link it to your security system.

When creating a myADT account, make sure that you review all available notification settings and add appropriate contact information. This includes email addresses, phone numbers and text message recipients. In many cases, you may even be able add contacts from outside of your home such as family members or friends who live in another area so they can respond if necessary.

You will also want to consider adding additional contact information for babysitters or regular visitors who may need access to the alarm system while you are away from the premises. You should also consider adding non-emergency contact information such as doctors and schools so that these contacts can be informed in case of an emergency.

To ensure setup is complete correctly, make sure that all notifications have been added and verified by receiving test notifications on all accounts. Once notified, check each account for response instructions and confirm receipt of any alarms or alerts sent out immediately following installation. Having properly setup notification settings will help provide peace-of-mind when it comes to being informed while away from home or when timely help is needed during distressful times.

Program the control panel

The control panel is the hub of all your home security activity and can be programmed to fit any number of needs. The ADT system comes with pre-programmed default settings designed for a single user, but additional users can also easily be added.

It is important to make sure all codes are updated regularly for maximum security. You can program the control panel to alert you via phone or text message in the event of an alarm or low battery situation. In order to program the control panel, you should first power up the system by inserting and connecting batteries into the main unit. Once that’s done, you must create a master code. This code will be used to access all communication with the control panel and should never be shared with anyone else, including house guests and family members.

Once your master code is set up, you can begin programming additional user codes and setting up other features such as alerts, chimes, and sirens. The ADT Keypad makes it easy by walking you through each step on its web-based user interface -allowing you to customize your settings quickly and conveniently from anywhere in the world!

Final Touches

When it comes to installing an ADT home security system, the final touches are the most important. You’ve already gone through the hard work of mounting the sensors, routing the cables, and setting up the control panel. Now, it’s time to make sure the system is properly powered up and all of the components are working properly. Let’s take a look at how to fine-tune your ADT home security system for optimal protection.

Set up a monitoring service

Once you have completed installation on your ADT home security system, the final step is to set up a monitoring service. ADT’s dedicated team of alarm response professionals are available 24 hours a day, 7 days a week and will be alerted whenever your security system detects an emergency. Once alerted, the team will contact you or any other designated contacts to inform you of the emergency situation and take appropriate steps to ensure your safety.

You can choose between several different packages for your monitoring service and customize it according to your needs. A few of the basic packages that ADT offers include Basic Monitoring, Broadcast Monitoring and Voice Pathing Monitoring. Basic Monitoring provides prompt notification via text or email in case of an emergency and basic customer support services by phone. Broadcast Monitoring adds personal support along with extended services such as home automation control, Video Relay Service (VRS) access to their monitoring center, remote access capabilities and mobile device control options so you can manage your system remotely even with limited data connection speeds. The most comprehensive package is Voice Pathing Monitoring which includes all features mentioned previously plus voice recording options for even greater clarity during alarm response calls and secure cloud storage for video recording activity from cameras connected to your security system.

ADT also offers specialized services tailored to commercial buildings as well as schools and other educational establishments, so it’s worth researching which package best fits YOUR particular requirements before making any decisions!

Label the system components

Labeling the system components is one of the most important steps when installing an ADT home security system. This will enable you to quickly identify any areas where a device needs to be added or replaced. Label each device before moving it and while it is still in the packaging. Begin by labeling each wire according to its purpose and its color code. Mark each zone according to the room number and then clearly label each keypad, control panel, window/door sensors, motion detectors and other alarm components with tape or adhesive labels with clear descriptions of their location and type. Be sure to label all parts of your security system clearly. This will make troubleshooting late much easier when any issues occur with your ADT home security system.

Install the signage

Once you have installed the components of your ADT Home Security System, it is time to install the signage. This is an important part of your security system that lets potential intruders know there is a monitored system in place. The minimum recommended signage for an ADT Home Security System includes a window decal and a yard sign.

Window Decals: Place either the window decal or door sticker on each of the entrances to your home. Be sure to place them in an area that is easily visible from outside.

Yard Sign: Installation of the yard sign is easy and should be done with care so it stands up against weather conditions over time. The best location for your yard sign is near a sidewalk, walkway or driveway; this way, passersby will be able to see it easily as they approach your home or leave.

Final system check

After successfully installing your ADT home security system, it’s time for a final check to make sure the system is working properly. This is an important step to finishing the installation process and ensuring that everything is in working order.

This step consists of several simple checks to verify that each device has been installed correctly and their functions are tested. Here’s what you should do:

1. Double-check all connections to ensure they’re secure and no wires are loose or exposed.
2. Make sure all components are correctly labeled according to your instructional manual.
3. Double-check batteries on motion sensors, glass breakage detectors, door/window contact sensors and smoke or heat detectors before activating the system.
4. Review all terminals, panels and keypads for any signs of abnormality including loose screws or plastic bits due to previous installation work or package damage before powering up the main panel with electricity (wall outlet connection) or using a backup battery for alternative power sources (like a car battery).
5 Activate all programmed devices by testing a few codes on the keypad (for example, arming and disarming).
6 Test every single device from each zone following the on-screen/keypad instructions provided by ADT as listed under options like ‘By Name’ OR ‘By Zone’.
7 Confirm motions sensors detect movements accurately when you walk past them within their programmed range (15 feet – 20 feet).
8 Check windows to make sure contact sensors have been placed properly after adding some anchoring materials required for more secure fitment (double sided tape). 9 Make sure monitored points in each zone activates alarm at least two times after successful programming with corresponding indicator light activation on main panel board/display board OR app notifications as per applicable option availability opened by default/selected before painting covering carpets behind them etc.. 10 Step back further away while arming/disarming using a remote control or key fob provided at purchase time so you can ensure long distance signals reach receiver capsule located inside main panel board without any facing issues while access attempt made from outside entryway areas too!
