DSC 1555RKZ Access Code

We bought a home with an existing security system but did not get the access code. Yesterday my wife armed the system and no code I have found in any manual or thread so far has worked (0000, 1234, 5555). How do I reset the access code / installer code / master code if I do not know what the current code is?

You have the worst scenario. There is no easy backdoor into a DSC panel, especially if it's armed. Basically, short of a lucky guess at the arming code, the only thing you can try is a hardware default of the system, and _hope_ that the installer lockout was not set.

This means that all of the system configuration settings will get wiped out, so it's a pretty extreme choice.

Websearch for an installer manual first using the phrase "DSC PC1555 install manual"

The defaulting instructions are also posted in the FAQ sticky: http://forum.doityourself.com/electr...e-posting.html
