Visit the ADT official Web site at www.adt.com. Contact ADT's home monitoring telephone center by dialing the phone number listed on the home page. You will speak to a home security consultant who will offer you several different home security services.
Choose one of the services offered by the ADT home security consultant. Schedule a home installation at a date and time that is suitable for you. A certified ADT installer will visit you at that time to install the ADT alarm system.
Allow the installer time to mount the digital keypad and install up to three points of protection in several parts of the house. Inform the installer of any special needs or requests so the installer can install the system suited to your needs.
Follow the installer's instructions after the hardware has been mounted and set up. During the installer's short demo, pay attention to the instructions to learn how to operate the newly installed security system.
