You can set up the ADT Safewatch 3000EN security system for both fire and burglary protection, but you can't change the control panel settings without entering the correct security code. A four-digit security code was assigned when the system was originally installed; you can change this code at any time to another four-digit code. The current security code is required in order to reset it to a new code.
Enter the current security code on the control panel.
Press "8." Press "02."
Enter the new security code. Enter the new security code a second time.
