Thanks Cliff, I've been waiting for this to come in the mail for 2 months now. Do you know how I can get the Master code for my system. The system was already installed in the home I purchased in July, however the owner did not use it, apparently it was installed by the previous owner so I really have no info on the system, basically I just want to make it functional, I'm not interested in monitoring.

The master code is set using the installer code. The factory default install code is 4112. It's probably been changed. The way to get the current installer code is to power the system down and press * + # within 50 seconds of reapplying power. Then enter #20. This will read back the installer code. Exit program mode with *99.

To change the master code follow the instructions on page 79 of the install manual: [installer code] + 8 + 01 + [new master code]. The keypad will beep once if the code is accepted.

Do this in a fairly smooth set of keystrokes. More than a second or two hesitation between keystrokes will result in the code not being changed.
