INTRODUCTION 
DK-2891 is a self-contained two output relay, vandal resistant and 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.

The DK-2891 has two versions. Version A comes with the Output Relay contacts 1 and 2 for door strike and auxiliary control respectively. The Version B comes with Output 1 for door strike and Output 2 for door bell activation.

DK-2891A – Output Relay 1 & 2 Controlled by User Codes / Cards
