The encrypted non-contact RFID controller for access control BKU518 works with special encrypted 125kHz ASK LESI keys that cannot be copied! BKU518 is a standalone RFID electronic controller with transistor output for access control, with mini sizes: 45 mm long and 25 mm wide, which can be installed in almost any location. The controller is used to control electronic locks, various other devices (car locks, control of central car locking, switching on and off production lines, etc.), access control in elevators. BKU518 is controlled by a master key, which adjusts the operation of the system and records, deletes, disables electronic keys. The master key is programmed additionally! The device can also be controlled via computer, smartphone, remotely via SMS (purchased separately). The programming and operation of the system is described in the enclosed product manual.
BKU518 CAN WORK WITH UP TO 7 READERS! (if you want to connect more than 7, contact us)
The product includes:
- Controller BKU518,
- Reader LRFD34 -2pcs.
- Master key for system and key management,
- Detailed documentation.
The encrypted RFID key operates at 125kHz and combines two keys into one. It has two parts – the encrypted part and the ordinary part. Due to this, this type of key is extremely versatile because it can work as an encrypted key in encrypted systems and as a simple key to ordinary systems. So, you will only carry one key again!!!! The ordinary part of the key can be copied and it will work with the ordinary systems to which it is written, but the encrypted part of the key cannot be copied !!! For example if you have encrypted access control system on your home door ), and standard system on your shared entrance door , the Encrypted L1 key can work with both of them. A standard key can work only with the standard system on the entrance door. If a copy is made from the original Encrypted L1 key, the copy will work only with the standard system, but not with the encrypted system in your home door.
The BKU518 is controlled by a master key, which adjusts the operation of the system and records, deletes, disables electronic keys.. The master key is programmed additionally! You can see how this is done HERE! The device can also be controlled via computer, smartphone, remotely via SMS (purchased separately). The programming and operation of the system is described in the enclosed product manual.
It has memory for events which means that it memorizes who and when opened the door, and many more events.
Has protections agains shortcut, reverse polarity of the power supply, overload, scanning of electronic keys
Unlocking is done with an electronic key (RFID card, tag) that approaches or touches the reader of the device. An electronic key can be programmed to unlock and lock many doors (for example, home, garage, cellar, building entrance door, elevator, and more). Each electronic key is remembered in the system with an individual number, which allows it to be deleted without its presence, and all other keys to continue to function normally. From the inside the lock can be unlocked with pressing a button (for locks EMB300 and BKB100) or the door handle (for electromagnetic strike EMH)
The BKU518 also allows a reader to be placed on the inside of the door, so a valid key must be provided to unlock the door when exiting. The controller can also control up to 7 readers. (modification is made for more than 7)
The encrypted key can be transmitted from one Bulkey system to another BulKey system through specialized software and a data cable. If the system is plain (unencrypted), it will be ported as a simple key. It can be transferred from an ordinary system to an encrypted system, then its encrypted part is also transferred and it will function seamlessly in the new system!
Application of the autonomous ENCRYPTED RFID controller Bulkey BKU518 for electronic locking and access control to entrance doors. They control electromagnetic lock type Magnet, electronic lock with stud type Bolt, electromagnetic counter and others. The principle of operation is as follows: On the outside there is a reader with a two-color LED, which lights up in red when the lock is locked and in green – when it is unlocked. A valid electronic key is supplied to the reader, the lock is unlocked for 15s with a door sensor installed or for 5s without a door sensor and the door can be opened. When the door is closed, the lock is automatically locked (if this mode is selected). From the inside, the lock is unlocked by pushing a button when magnet or bolt locks are fitted, or by a door handle for a lock type counter.
Application of the autonomous ENCRYPTED RFID controller Bulkey BKU518 for access control to elevators by turning off the floor selection buttons in the elevator cabin, the principle of action being the following: The reader is installed in the cabin, which allows or not to select the floor from the button cabinet. The reader has a two-color LED, which if lit in red indicates that the floor selection buttons are off. After submitting an electronic key programmed to the system, the reader LED lights up in green and allows the floor selection button to operate for 5 seconds (adjustable from 1 sec to 4 min). After these seconds have elapsed, the pushbutton operation is automatically disabled and the LED lights up in red again. This option allows the elevator to be called on the floors by everyone, and the choice of floor from the pushbutton in the cabin can be made only with a valid electronic key!
