Inputs 1 and 2 – Extended Door Controls
When extended door controls are set, Input 1 is used for the door contact
and Input 2 is used for a request to exit device contact. See Using
Extended Door Controls for more information.
Input 3 – Presence Sense
Input 3 is used for the presence sensor when that option is enabled.
When enabled, this option requires an input from a vehicle loop detector
or a pressure mat before the keypad will accept any input from the
customer. This can be used to prevent people from walking up to a drive-
through gate and entering a code.
