 ENCRYPTED RFID contactless access control controller BulKey BKU517, puts an END to UNCONTROLLED KEY COPYING, through innovative encrypted RFID chip technology. It is an efficient solution for locking home, office and public entrance doors using electromagnetic locks and electronic keys, as well as the ability to electronically lock elevators by blocking the call and floor selection buttons.

For example, if you have an encrypted control system in your elevator (with BKU517) and a standard system on your common entrance door (with BKU417), the encrypted RFID L1 key can work with both. The standard key can only work with the standard front door system. If someone tries to make a duplicate of the encrypted L1 key, the duplicate will only unlock the standard system, but not the encrypted system in your elevator.

NEW! Control your controller via an app from your phone! There is also a FREE version. Change settings with just one click. Quickly and easily add new keys or keep track of who activated access control when. Learn more on the BulKey App product page!

The equipment of the system includes:

  • Controller BKU517,
  • Preprogrammed Encrypted L1 Master key
  • Electronic reader (choose from options)
  • Detailed documentation.

What is BKU517?

BKU517 is a stand-alone ENCRYPTED RFID controller for access control and management of electronic locks – the “brain of the locking system”.

BKU517 works with special encrypted keys with Lesi type RFID protocol, which cannot be copied by locksmith! The encrypted keys working with BulKey BKU517 have 128 bit dynamic code and are extremely good value for money and protect the key from being copied by standard copying devices. They are suitable for access control for building doors and elevators. An advantage is that they can also be used on standard unencrypted systems, allowing one key to be used for many different devices.

A single electronic key can be programmed to unlock and lock many doors (eg home, garage, basement, building front door, elevator, etc.). It can be easily and quickly prohibited or allowed its operation to a given door. Each electronic key is programmed in the system with an individual number, which allows it to be deleted without its presence, and all other keys continue to function normally.

Unlocking from the inside is done by pressing a button (for Bolt type and electromagnet locks) or by pressing the door handle (for counter type locks) or it could placed a second electroni readed for double sided access control. 

Split system
BKU517 combined with a reader represents the so-called Split system. This means that the reader and the controller are independent and can be mounted at a distance from each other. So if the reader (as the only visible part of the entire system) is attacked and broken, it will NOT unlock the door.

BKU517 is controlled by a master card (or key), with which system operation is set and electronic keys are recorded, erased, disabled. The device can also be controlled via computer, smartphone, remotely via SMS or via the Internet (modules are purchased separately). The method of programming, recording, erasing, status of a specific key, total number of keys in the system are described in the detailed instructions attached to the product and according to the algorithm patented by the LESI company. The reader and controller are built directly into the door frame, making the system extremely vandal-resistant! For your convenience, in addition to the detailed product description, we have also made tutorial videos on how to operate the keys

Apart from master key, it can be controlled by computer or phone app. The phone app also has a free version with which you can quickly and conveniently change settings to monitor events and keys. Check out more on the BulKey App product page HERE

Each system can be configured to network with others like it. The systems are addressable, allowing networking and common management via a single GSM or LAN communicator.

More details about access to the system with a password can be learned after purchasing the specialized software with data cable BulKey of the company LESI.

The BKU517 has a programmable event memory. With it, you will be able to review who unlocked and opened the door when, or when an unknown key was passed to the reader. Thanks to the built-in clock, you will be able to see the exact date and time of the event.

Hardware protections of BKU517

  • Protection against electronic key scanning
  • Short circuit protection and power supply polarity reversal
  • Protection from electric shock batons (when reader plate is inserted)
  • Resin covered PCB

 

Application of the autonomous RFID access control controller Bulkey BKU517 for electronic locking and access control to entrance doors. They control an electromagnetic lock of the Magnet type, an electronic lock with a spike of the Bolt type, an electromagnetic counter and others. The principle of operation is as follows: On the outside there is a reader with an LED that lights up red when the lock is locked and green when it is unlocked. A valid electronic key is fed to the reader, the lock unlocks in 15s with a door sensor installed or in 5s without a door sensor and the door can be opened. When the door closes, lock is automatically locked (if this mode is selected). From the inside, the lock is unlocked by pressing a button in the case of installed magnet or bolt type locks, or by the door handle in the case of a counter type lock.

Application of the autonomous RFID access control controller Bulkey BKU517 to control access to elevators by turning off the floor selection buttons in the elevator cabin, the principle of operation is as follows: The reader is installed in the cabin, which allows or not the selection of the floor by the buttonhole. The reader has a two-color LED which, if lit red, indicates that the floor selection buttons are disabled. After submitting an electronic key programmed to the system, the reader’s LED lights up green and enables the operation of the floor selection button for a period of 5 seconds (adjustable from 1 sec to 4 min). After

    The documentation is too long, but I guess it’s better than a short one. The product itself works good and as described. We use it for our office building and it truly provides security with the encrypted keys.

    I like the controller, it is small and easy to use, and most importantly secure. I wish we can have more colors of the readers. However I painted mine so it matched the door and it turned out great.
