RFID controller for access control BKU218 works with several different readers. The price is basic, only to the controller. Choose the reader from Product OPTIONS!!!

Here you can choose the kit with electromagnetic lock: Dropbolt BKB100, electromagnet EMB300, electromagnetic strike.

As BKU218 is a split-system which means that your reader can be mounted far from the controller. If the reader is attacked – the controller BKU218 remains save, and does NOT open the door.

Unlocking is done by an electronic key (RFID card or key), which approaches or touches the reader of the device. An electronic key can be programmed to unlock and lock many doors (eg home, garage, cellar, building front door, elevator, etc.) so you bring with you only one key, which is programmed to various doors. Each electronic key is stored 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 electronic keys are controlled with a Master key, through the system reader. This is the master key of the system, which is used to program, save, delete or temporarily disable the operation of a key. The master key is additionally programmed!

Application of the autonomous RFID controller Bulkey BKU218 for electronic locking and access control to entrance doors. They control an electromagnetic lock type Magnet, an electronic lock with a spike type Bolt, an electromagnetic striker and others. The principle of operation is as follows: On the outside there is a reader with a two-color LED, which glows red when the lock is locked and green – when 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 locks automatically (if this mode is selected). On the inside, the lock is unlocked by pressing a button with mounted magnet or bolt locks, or by the door handle with a counter-lock.

Application of the autonomous RFID controller Bulkey BKU218 for access control 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 forbids selection of the floor on the boutonniere. The reader has a two-color LED, which if it is red indicates that the floor selection buttons are off. After applying an electronic key programmed to the system, the LED of the reader lights up in green and allows the operation of the floor selection button for a time of 5 seconds (can be adjusted from 1 sec to 4 min). After these seconds, the operation of the floor buttons is automatically disabled and the LED lights up red again. This option allows the elevator to be called on the floors by everyone, and the choice of floor from the boutonniere in the cabin can be done only with a valid electronic key!
