The feature will operate when the door has been released from the keypad or from the REX input (see Section 3.6). Note that to disable the anti-tailgating feature and return full function to the HCD and UCD terminals, put the unit into program mode and enter 8-4. Note that the DK- 26 supports a more powerful anti-tailgating feature which incorporates an alarm signal through the use of the programmable relay. Read Section 6.4 for details.

7.5 WIRING WITH SECURITRON'S TOUCH SENSE BAR AND MAGNALOCK

The DK-26 is often used with Securitron's Touch Sense Bar and magnetic lock. The following drawing shows wiring for this particular configuration. Note that the REX input is not used. Since touching the bar opens the door in a single motion, you do not want to activate the DK- 26's timer which would only serve to keep the lock released for a longer time, thereby reducing security. Another potentially confusing element is that the Touch Sense Bar is also a powered device which operates most reliably when it is constantly powered. The drawing shows a wiring method that is applicable for either an AC or DC power supply (naturally, the supply voltage must be matched to the lock voltage). Note that a variation of this wiring scheme could be desired if you are using the second pole of the DK-26’s lock control relay to shunt an alarm system (see Section 7.3). You would then want the Touch Bar to operate the DK-26’s lock control relay in double break fashion so that the alarm system is shunted both for entry and exit. Simply follow Figure 9 except also connect the blue and orange wires from the Touch Sensor to terminals SRC and REX on the CPU board (as well as connecting the second pole of the lock control relay to the alarm point as shown in Section 7.3).

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.
