This programming step sets the system MASTER CODE. The master code is the four-digit number REQUIRED to gain access to
the system memory.

The 1812 comes from the factory WITHOUT a master code programmed into it.

You MUST program a MASTER CODE.

The Master Code can ONLY be programmed from the system keypad.

2.2 Programming the Master Code

Master Code
Push Button

Step 1. Open the cabinet of the 1812 and press the master code button (See below). The Blinking LED right above

the master code button will stop blinking and remain ON.

Step 2. Enter a four-digit master code then press

Step 3. The LED will revert to Blinking. Close the cabinet.

You should write down your master code, see note below.

Note: After you press the master code push button, the blinking LED will stay ON indicating that you are in
the master code programming sequence. If a master code is not entered within 10 seconds, the master code
program sequence will automatically end and the LED will return to a blinking state indicating that you have
exited the master code programming sequence.

Programming Documentation Note: There are programming log sheets in the back of this manual to document your specific
master code, and keep track of all other programming that is preformed to this 1812 Plus. Keep this with all other system
documentation for future reference. There is no way of retrieving the master code after it has been programmed in. If you
forget it, you will have to program in a new one but all other previously programmed information will remain intact.

Multiple 1812 Master Codes Note: The master code number is used to distinguish each 1812 when
multiple 1812s are connected together. They CAN NOT function together with duplicate master codes.
