INTRODUCTION 
DK2835 is a self-contained two output relay, vandal resistant and weatherproof keypad. It has been designed for full feature stand alone access control applications. 

It is expandable to work with an optional decoder (DA-2800 or DA-2801) for high security split-decoded operation. The keypad can plug in Wi-Fi Module (AP-02) as a Wi-Fi Keypad. 

It is also compatible with the auxiliary card reader (AR-2802) and the auxiliary keypad readers (AR-2806, AR-2807 and AR-2809) for upgrading a stand alone or split-decoded system to multi-station operation.

The keypad is ideally for door strike and alarm arm-disarm controls. It is also a programmable industrial timer (from 1 second to over 24 hours) for automatic operator system.

DK-2835 has two relay outputs.
