The master code is the four-digit number REQUIRED to gain access to the system memory. It comes from the factory pre
programmed using the
“Last 4-digits of the control board serial number”
but can be reprogrammed to any 4 numbers
desired. Follow the 3 steps below to reprogram the master code. Plug in 1812’s 24 VAC transformer before programming.
The Master Code can ONLY be programmed from the system keypad.
2.2 Master Code
Step 1. Open the cabinet of the 1812 and turn the master code switch ON (the small sliding switch, see below).
Step 2. Enter a four-digit master code then press

.
Step 3. Turn the master code switch OFF and close the cabinet.

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 Classic. 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.
