D279A Operation and Installation Guide

D279A

Programming

5.0 Programming

5.1 User Passcode

The D279A Independent Zone Control comes programmed with a standard passcode of 1234. 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

If the standard passcode is recovered while the D279A is armed, an alarm will be generated at the main panel.

Default passcode procedure:

1. Connect jumper J3 across the top two pins.

2. Press the [BLANK] key once.

3. Press the following key sequence: [BLANK], [2], [7], [9] (mastercode).

4. Repeat Step #3.

5. The buzzer sounds a beep for 3 seconds 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 feature is disabled

when the jumper plug is placed across

the bottom two pins.

1. Connect jumper J3 across the top two pins.

2. Press the [BLANK] key once.

3. Enter the old passcode once ([1], [2], [3], [4]).

4. Enter the new four digit passcode twice.

Note: Do not program the same digit twice in a row (4556), or program the first and last digit the same (4564). Do not use

the [BLANK] key for any digits in the passcode.

5. Arm and disarm the D279A to test the new passcode.

To prevent further use of this feature, place jumper J3 across the bottom two pins (see Figure 3).
