INTRODUCTION DK-2831C is a vandal resistant 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. 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.
