Learn how to change the master code, add or delete user codes and change the installer code on most Honeywell alarm systems right here!

My new habitat came protected by a DSC alarm system. The system consists of a keypad, model RFK5501 in my case, and a control panel, PC1616 for me.

The model number of the keypad is hidden in very tiny text on the top edge of the keypad. The control panel is the hub of the alarm system and is located within a metal box within an interior wall.

I had to open the metal enclosure to find the model number of the control panel. To change most settings one needs a user access code.

For the PC1616, there are 48 user access codes numbered 01 through 48. Other models have more codes.

Access code 40 is the master code. This code can be used to change all other codes. To change a user access code, one would enter *5[master code][code #][new code]. So, for example, if the master code is 1234 and one wants to add a second code (01) as 5678, one would enter *5 12.

To change the master code to 5678, the sequence is *5 12. In the sequence, after each accepted entry, the keypad will emit three beeps. When an entry is rejected, it will sound one long beep. When finished, pressing # until the ready light comes back on and the screen blanks will return the keypad to normal operation.

Changing the master code is one important level of security, but there is an even more privileged code with which a person could compromise the DSC security system. This code is the installer code. With the installer code, it is possible to change the master code and all other settings. New systems come with a default installer code programmed, 5555 in the case of the PC1616. If the installer hasn't changed the installer code, it's a good idea to change it since it potentially allows anyone to have control over your security system. DIY'ers should change the code regardless to prevent unwanted access from even the installer. The installer code is changed by entering the installer programming via the *8 command. Quicken Qdf File Corrupted Files there.

The complete sequence is *8[current installer code]006[new installer code]. For example, the following sequence sets the default installer code (5555) to 1234: *8 5555 006 1234. Then the # key is pressed until the keypad returns to normal operation. In the case of entering the installer code, an accepted code is signaled by six short beeps instead of three. If the new installer code is forgotten, the code can be reset to the default code following a hardware reset procedure at the control panel. For maximum security, there is an installer lockout feature that will prevent the hardware reset from resetting the installer code. If the installer code is unknown and the installer lockout is enabled, the only solution to regain complete control of the system is to replace the control panel with a new panel in factory default condition.

The DSC 1616, DSC 1832 and the DSC 1864 all come with the same default factory master codes and installer codes. If you just bought or defaulted your PowerSeries panel, the codes will be at these defaults. If you are taking a system over, there is a high probability that the codes will be changed.

But it is always a good idea to at least try these codes first as it is not unheard of for the installer code to be left on the default. The default master code is 1234. The master code is automatically assigned to user number 40.

The master code is the first user code that comes programmed on the panel and it cannot be deleted, but it can and should be changed. The master code allows you to do quite a few things on the alarm system. You can arm and disarm the system and any partition on the system if you are using multiple partitions. It will allow you to access the *5 menu to add, change, and delete other user codes. You can also access the *6 menu which allows you to do numerous things such as checking the event log, changing keypad brightness, or setting the time and date. You will want to change this to a code that only you know so that someone does not break in and just try to enter 1234 to disarm the system.

This would make your alarm system much less effective against a break in. The default installer code for a DSC is 5555. The installer code is the code that is used to get into the DSC programming mode so you can set the system up and make changes to panel programming. Cracking Decane Word Equation there.

Having the installer code is the most important part of setting up the system. You will not be able to arm or disarm with the system with the installer code. But if you have the installer code you can make any changes you want to the system, including changing the master code. The installer code, like the master code should ideally be changed to a number that is not easy to guess. While it is perhaps not as critical as changing the master code for security purposes, if someone has access to the system while it is disarmed and they have intentions to make changes having an installer code that is not the system default is important.
