SKU: BKB101 Category:

Electric Bolt BKB101  with state of the lock is used for locking and access control to doors with mandatory emergency safety – shared entrance doors, interior office doors, doors in industrial, public and office buildings and premises and others. Due to the fact that the lock is emergency safe and the overall dimensions are extremely small, it allows the lock to be mounted on partition office, corridor and entrance doors.
Its installation can be dug (hidden) in the frame or door, or external.

Electric Bolt BKB101 differs from BKB100 in that it has an output for the state of the lock – whether the bolt is outside or retracted. While the BKB100 only reads the door position – open / closed.

Unlike conventional mechanical locking systems, where the lock is located directly behind the keyhole and thieves know exactly where to attack – the BKB100 electronic lock can be located anywhere in the door frame, no matter from where it is unlocked. This would make it extremely difficult to do a targeted attack on the lock.
If the lock is mounted on the door leaf, a suitable transition element must be selected to ensure reliable transmission of electrical signals from the fixed to the movable part (see HERE).

The product consists of 2 parts – body of the lock and opposite plate. The distance between them should be less than 8 mm to ensure that the bolt will enter the hole in the plate.
There are 5 cables: Red (+), Black (-), Orange (Open), Green (NO), White (COM)
Time delay setting, 0/3/6/9 sec.

The most suitable control of this lock are the mini controllers developed by us, models Bulkey BKU417, BKU517 (for RFID keys) and Bulkey BKU419, BKU519 (for iButton keys), which can be hidden in the windows or in the door. Despite their small size, they combine in one key reader, control of a lock, buzzer, button (incl. Intercoms), have an output for connection to a computer, through which, in addition to the Master key, you can control the status of user keys. It is also possible for the lock to be remote controlled.
