 Keypad Conguration
Voltage Selection
The factory default setting for the Keypad voltage is 12-24VDC.
Verify that the jumper is removed or placed over only one pin. For
5VDC, the jumper should be placed across both pins. If changing
the voltage is necessary, make sure the power is removed rst.
Keypad Output Selection
Once the voltage jumper is veried or correctly set:
1. Remove power.
2. Jumper the two pins above the connector labeled “CONFIG.”
3. Apply appropriate power. (You should hear 4 beeps and the
RED LED will ash and the GREEN LED will be solid.)
4. Now that the Keypad is in conguration mode, select the de-
sired output by entering the conguration number followed by #.
a. Keypad Output
Keypad Output Conguration Site Code

power in order to complete the conguration procedure. Note: If
the conguration jumper is not removed, the LED’s will ash and
the Keypad will beep continuously.
