The electromagnetic strike is used for access control an it’s mounted on the door frame against the tongue of the already existing mechanical lock in the door leaf. This construction allows access from the outside of the door with both an electronic key and a mechanical one (optional). You can get out of the inside by pressing the lock handle. There must be a ball handle on the outside of the door and a handle on the inside.

The electromagnetic strike has four varieties:

  1. Ordinary – typical for common entrance doors of residential buildings
  2. With memory – typical when connected to an intercom system
  3. With thumb – typical for office doors
  4. With memory and thumb – typical for office doors with remote unlocking

The electromagnetic strike draws current only at the moment of unlocking. When the power is turned off, it remains in the locked position. In order to function normally in the absence of power, it is necessary to install an emergency module with a battery. The power supply is AC / DC – from 6V to 14V. The current consumption is about 1A. When controlled via a relay, a reverse diode must be installed to prevent scale from forming in the relay contacts. It is not recommended to apply unlocking voltage for more than 15 seconds.

The force of the spring is 1kg. This is the force with which one has to push the door to open it when the strike UNLOCKED. However, if the door has solid seals or strong air flow that pushes it out, then even if you press the unlock button, the strike will not unlock. The person must pull the door towards oneself and then strike will unlock it. In these cases, the reinforced strike is recommended, which can be found HERE.

The lock is controlled electrically, by controller and reader, as well as by intercom installation

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.
