SECTION 2 – PROGRAMMING
Before You Start
IMPORTANT! We strongly suggest that you become familiar with these programming
instructions before beginning any programming of the 1838 Access Plus system.
The 1838 has been programmed at the factory with many of the programming parameters already set
(default setting). There is no need to reprogram these parameters unless you want to change them.
For easy reference, refer to the chart on page 24 that list the various programming functions and their
default settings.
2.1 Programming the Master Code
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 master code can only be programmed from
the system keypad.
Default setting is NONE. You MUST program a Master Code.
1. Open the cabinet and press the master code button. The Blinking LED next to the button will
turn ON.
Note: After you press the master code push button, the LED will turn 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.
2. Enter a four-digit master code then press *. [ _ _ _ _ * (beep)] (The LED will revert to
Blinking).
3. Close the cabinet.
