"How to Program Unlock"
17 March 2011
Summary: the Digital Security Controls (DSC) Power632 home security system's PC1555MX circuit board is keypad programmable. When a system is installed, most installers "lock" the PC1555MX so that programming changes can not be made. To "unlock" the PC1555MX you must know the current "Installer Code".
Background:
The Digital Security Controls (DSC) Power632's PC1555MX circuit board is programmable.
Via keypad programming, the Power632 is tailored to a specific installation, home.
The Power632's PC1555MX is shipped from the factory with 2 default codes: "Master Code" and "Installer Code".
The "Master Code" is used to enter, edit or delete arm-disarm access codes. The default "Master Code" is 1234.
The "Installer Code" is used in all other PC1555MX programming. The default "Installer Code" is 5555.
When a Power632 is professionally installed, the installer may or may not have changed the "Installer Code."
When a Power632 is professionally installed, once all programming has been completed and the system is fully functional, the installer may or may not have program "locked" the PC1555MX.
"Locking" the PC1555MX prevents additional program changes.
If programming changes to the Power632's PC1555MX circuit board are required and you wish to do program changes do-it-yourself (DIY), you must know the current "Installer Code".
How to Unlock the Power632, PC1555MX circuit board:
Go to a keypad and enter the following:
* 8 "Current Installer Code" (Default "Installer Code" = 5555 and if you do not know of another "Installer Code" enter 5555)
If your keypad "Armed" light emitting diode (LED) lights up and\or your liquid crystal display (LCD) say "Program", the "Installer Code" you entered is valid.
Now enter 991 # #
Your PC1555MX is now program "Unlocked".
You can now make program changes to the PC1555MX.
Invalid "Installer Code":
If your keypad "Arm" light does not light and you do not see "Program" or its equivalent on your keypad, the default "Master Code" has been changed and the "Installer Code" you entered is invalid.
You options now are:
- Ask the previous homeowner for the current "Installer Code".
- Ask the security company that installed the system for the current "Installer Code".
- Either replace the PC1555MX circuit board yourself and DIY program it or pay a security company to replace the PC1555MX and program your system.
Note: you can not do a hardware reset on a PC1555MX board that is "locked". You must know the "Installer Code" and unlock the board first if you wish to do a hardware reset.
