Feedback and Entry Overview
The DK-37 comes with green, yellow, and red LED indicators above the keypad. These three
indicator lights provide feedback during operation. When the DK-37 is in Wiegand mode there is
no yellow feedback light when connected to an access controller. The yellow light is designed to
work with the Securitron DKC Digital Keypad Controller. The three indicator lights are intended
for operation through an access controller either through a dry-contact connection to ground or
an open-collector driver. Please refer to the access controller for information about the meaning
of the indicator lights.
