6.5 NIGHTLIGHT FUNCTION

When this function is selected, the act of touching any key will operate the programmable relay for five seconds. This may be used to turn on a lamp directed at the Keypad at night so that the person using the Keypad can see to enter the code. Put the unit into program mode and enter 7-7. You will see the two flash confirmation. Then, exit program mode. Note that selection of this option means you give up the opportunity to implement a doorbell or other use of the programmable relay.

To return the programmable relay to factory set (doorbell) function, put the unit into program mode and enter 7-8. You will see the two flash confirmation. Then, exit program mode.

7. ADDITIONAL HARD WIRED OPTIONS

7.1 DUAL PAD OPERATION

If keypad control from both sides of the door is desired, two keypads can be connected to one CPU Board. Simply put the colored wires from both keypads into the appropriate terminals on the CPU Board such that 2 wires are in each terminal. Either keypad will then be able to release the lock and both keypads will beep and illuminate their LED's when either one is used. Two is the maximum number of keypads that can be connected to one CPU Board. Note that in the unusual case where both keypads are being used simultaneously, the door will not release as the sequence will certainly be disturbed. Only one keypad may be used at a time. Be sure you don’t violate egress building codes when employing a keypad on the inside of a door. Check with your local building or fire department.

7.2 HARDWIRED CODE DISABLING

This means making a switch connection to the CPU board which will cause valid codes to not be accepted. The DK-26 has two terminals marked “HCD” and “UCD” which will respectively disable the Hard code and all User codes. Simply connect the SRC terminal to either of these terminals via an external switch and the respective codes will not function while the switch is closed. Alternately if you supply +12V or +24V from the DC+ terminal to either of these terminals, it will have the same effect.

The main reason for doing this is to support

day/night operations. For example, you could

 

allow all User codes to be active during the day

 

 

 

 

but disable them at night by closing a switch

between SRC and UCD. The Hard code would

could have no Hard code programmed so that

such as Securitron’s model DT-7. It’s finally

 

 

 

 

possible to flip the codes (Hard and all User) so that, for example, User codes are active only during the day and the Hard code is active only at night. An SPDT switch or relay is needed to do this as the drawing to the right shows. Note that you won’t be able to use one of these disabling features (Hard or User) if you have implemented the door prop alarm (Section 6.4) or anti-tailgating (Section 7.4) features. These reassign one of the terminals.

DK-26 specifications

The Assa DK-26 is a state-of-the-art electronic locking system designed to provide enhanced security for a variety of applications, including commercial, institutional, and residential environments. This locking solution is characterized by its robust construction, advanced technology, and user-friendly features, making it a popular choice among security professionals.

One of the standout features of the Assa DK-26 is its innovative design, which combines mechanical and electronic security elements. The locking mechanism utilizes a high-security cylinder, ensuring that unauthorized access is thwarted. This cylinder is key-operated, allowing for traditional key entry while also supporting electronic access control, offering flexibility to users.

The DK-26 is equipped with advanced electronic technologies that enhance its functionality. One of the key technologies integrated into this system is RFID (Radio Frequency Identification). This allows users to gain access using key fobs or cards that contain embedded RFID chips. The system can be programmed to allow or deny access based on time schedules, occupancy status, or individual user credentials, providing a high level of control over who can enter a facility.

Another notable characteristic of the Assa DK-26 is its ability to integrate with various security management systems. This compatibility allows for centralized control and monitoring of multiple locking devices, enabling security personnel to efficiently manage access across an entire building or campus. Additionally, the DK-26 features real-time audit trails, which log all access attempts and can be reviewed for security audits or investigations.

The DK-26 is designed for durability and resilience, featuring weather-resistant materials that make it suitable for both interior and exterior applications. Its sleek and modern aesthetic adds to the appeal for businesses looking to maintain a professional appearance while ensuring optimal security.

Installation of the Assa DK-26 is straightforward, as it can be retrofitted to existing door hardware without requiring extensive modifications. This ease of installation, combined with its reliable performance, makes the DK-26 an intelligent choice for anyone looking to upgrade their locking systems.

In summary, the Assa DK-26 electronic locking system combines high-security mechanical features with advanced electronic technologies, making it a versatile and effective solution for securing a diverse range of environments. Its RFID access capabilities, integration with security management systems, and robust construction make it a standout choice in modern security solutions.
