Electromagnetic Lock for Access Control EMB300 is used for doors with mandatory emergency safety – shared entrance doors, interior office doors, doors in industrial, public and office buildings and premises and others.

From OPTIONS you can choose an additional mounting plate depending on the direction of opening the door:
L plate for doors that open outwards (push when exit)
LZ plate for doors that open inwards (push when enter)

The electromagnet is designed for rooms with a high degree of security, but with mandatory emergency safety, because when there is no voltage applied it unlocks. It can be used for any type of door and is the best choice for electronic locking of shared entrance doors of residential buildings. Due to the lack of mechanical wear elements it is extremely durable and has a very long service life. There are no requirements for the condition and type of the door.

 Electromagnetic Lock for Access Control EMB300 consists of two parts – one is mounted on the frame and the other on the door leaf. It is mounted in the upper opening corner of the door for metal doors, and for all other types of doors it is desirable to put two magnets – one in the upper opening corner of the door and the other in the lower opening corner of the door at a height of 20-30 cm from floor. The installation of the two magnets prevents the twisting of the soft doors (aluminum, PVC, wooden) by double locking. It can also work without a mechanical lock, as it locks the door in the closed position. It is unlocked only electronically. A button for quick and easy unlocking of the door can be installed on the inside, instead of a valid electronic key. One magnet can withstand loads up to 300 kg and constantly draws current in the locked position. It can also be controlled by remote control, as well as from an intercom.

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.
