INTRODUCTION
DK-2890 is a self-contained two output relay weatherproof keypad. It combines the digital keypad and proximity EM card reader in one unit.

The keypad has been designed for 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. 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.

Its Output 1 is controlled by user codes/cards ideally for access control and the output 2 is controlled by the bell button mainly for low power door chime activation.
