D268, D269
Operation
Operation (continued)
Open/Close Output
This output presents an open circuit to the panel when the D268/D269 is disarmed, and a normal circuit when
the D268/D269 is armed and not in alarm.
Alarm Output Terminals
Two form C contacts, each rated at 2 Amps, are provided for an optional alarm device, such as a bell. This relay
is activated when the D268/D269 goes into alarm, and is reset when the D268/D269 is disarmed. A D136 Relay
needs to be installed in the D268 for this option.
D269 Keypad
Green LED - Loop Status
The Loop Status LED lights when both the delayed and instant loops are normal. It's switched off when one or
both loops are faulted. This LED is not affected by armed status.
Red LED - Armed Status
The Armed Status LED starts blinking when the correct passcode is entered to indicate exit delay time in
progress. This LED is on while the D268/D269 is armed. This LED is off while the D268/D269 is disarmed.
Warning Sounder
During entry delay, the warning sounder latches on until the D268/D269 is disarmed or an alarm occurs. If a
numbered key is pressed while the unit is disarmed and has a loop faulted, a warning sound indicates that it's
not ready to arm.
Standard Combination
You enter a four-digit passcode into the D269 Keypad to arm and disarm the D268 zones. The D268 is shipped
from the factory with a default passcode of 1234 or 2222. Once the unit is installed and power is connected, you
can change these numbers to a different passcode. This passcode is the same at all D269 Keypads connected
to that D268.
Programming
Programming or Changing the Combination
You need to install a jumper plug on J1 in the “A “ (COMB CHG) position (see Figure 2) to enable the passcode
change feature. To prevent further passcode changes, place the jumper plug in the "B" (NO) position.
You must know the existing (old) passcode before you can change it to a new one. If you do not know the
passcode, see Recovering the Standard passcode in this manual. If you make a mistake while changing the
passcode, wait 5 seconds and repeat the procedure. If the procedure is not completed within 60 seconds, the
keypad reverts to the old passcode.
Only change the passcode when the keypad is disarmed. Do not program the same digit twice in a row. Do not
program the first and last digits the same.
