User Passcode
The D279A Independent Zone Control comes programmed with a standard passcode of 1234 or 2222 (if the 1234
doesn’t work try 2222). Once the unit is installed and power connected, you can change these numbers to the
desired four digit passcode.
5.1.1
Recovering the Standard Passcode
Default passcode procedure:
1.
Make sure the D279A is in disarm state.
2.
Connect jumper J3 across the top two pins.
3.
Press [BLANK] once.
4.
Enter the mastercode 0279 twice. (Blank key is also 0 key)
5.
The buzzer sounds a beep for 3 sec. to indicate default passcode success.
6.
Arm and disarm the zone control to test the default passcode 1234.
5.1.2
Programming or Changing the Passcode
A four digit passcode is used to arm and disarm the D279A. This code can be changed only by first knowing the
existing (old) passcode. Change the passcode only while the D279A is DISARMED, and BOTH protective loops are
normal. If you make a mistake while programming, restart the procedure from Step 2. If programming is not
completed in 60 seconds, the Independent Zone Control reverts to the old passcode. As shipped, the J3 jumper
plug is placed across the top two pins, which enables passcode change (see Figure 3). The passcode change

4.
Enter the new four digit
passcode twice.
DO NOT program the same
digit twice in a row
(example: 4556).
DO NOT program the first
and last digit the same
(example: 4564).
DO NOT use the BLANK (zero) key for any digits in the passcode (example: 1023).
5.
Arm and disarm the zone control to test the new passcode.
To prevent further use of this feature, place jumper J3 across the bottom two pins (see Figure 3 above).
