    How to connect keypads and determine how many are allowed on the D2112 control panel.

    • A minimum of 5 feet of 22ga wire must be used when connecting the keypad. 
    • Shorting terminal 9 within 5 feet of the panel will cause the panel to operate incorrectly. 
    • The maximum wire length for all keypad wiring combined is 500 feet (22AWG). 
    Up to four keypads can be connected in parallel to terminals 8, 9 and 10 on the D2112.
