The AR0226 1-Wire Keypad is a keypad which can be connected to a DM device where a keypad is required instead of a swipe fob/access card. Some organisations prefer this as cards/fobs do not need to be distributed.

1. Set 4-Wire Plug function to iButton
This is the only step required to read codes from the keypad.
The keypad has an internal buzzer. However it is activated by applying 12V to the buzzer control line. There is no 12V output available on the Dart3 - so instead it is easiest to instead Connect an External Buzzer.
Ensure this parameter is set to have the buzzer sound when a trip is started and no PIN is entered
