Detex DTX-4100 - Manual (Page 7)

Wiring the 2000-8EX Output Module
If the Output Module is within 18 inches of the keypad, use the 6-
conductor wire harness, supplied with the Output Module, to make
the connection. If your Output Module is located more than 18
inches from the keypad (up to a maximum of 100 feet), you must
cut the wire harness in half and plug one half into the keypad the
other into the Output Module. Then connect the two using 22
AWG stranded and shielded cable. Make sure you connect the
wire harness pin to pin (pin 1 on the Output Module to pin 1 on the
keypad and so on). You must connect the drain wire from your
cable to the negative on your keypad (the black wire to your power
supply).
Performing the Programming Mode
Loopback
The keypad has a special loopback connection you can make to
enter program mode if you do not know the master code. Use the

Note: This procedure should only be performed by a qualified
security or lock industry professional.
1. Power down the keypad.
2. Connect the white/yellow, brown and white wires together and
disconnect any other connections to these wires.
3. Power up the keypad
4. Change the master code or default the keypad
5. Power down the keypad and remove the loopback connections
and reconnect any other wiring to these wires.
6. Power up the keypad.
Performing the Keypad Self-Test
After installing the keypad, IEI recommends that you perform the
keypad self-test once a year to ensure that the keypad is working
properly.
1. To perform the self-test, with the unit powered up, press the
following keys on the keypad: 7890#123456*
2. If all 12 key presses are accepted, the keypad enters self-test
mode.
3. The LEDs then turn on one at time with a beep in the
following order Red, Yellow then Green.
4. After the Green LED, the unit then flashes an LED to indicate
which operating mode the keypad is programmed mode.
Below shows which LED flashes for each mode:
● Standalone Mode: Red Flash
● Wiegand Front End Mode: Green Flash
● Secured Series Front End Mode: Yellow Flash
followed by rapid yellow flicker.
