    Smart electromechanical door lock – a surface-mounted 12V DC lock with one mechanical cylinder, designed for intercom and access control systems. The lock unlocks in less than 1 second, and if the door is not opened, it automatically locks again after approximately 5–8 seconds. Suitable for left- and right-hand doors opening inward or outward. The housing is made of iron, with a declared service life of more than 500,000 operating cycles. 

  • Smart electromechanical lock | 12V DC | single cylinder | automatic locking

    Surface-mounted smart electromechanical door lock with a single mechanical cylinder, designed for integration with intercom, access control and other door control systems. The lock features an automatic locking function: if the door is unlocked but not opened, the system automatically returns to the locked state after approximately 5–8 seconds. The design is suitable for left- and right-hand doors opening inward or outward.

    Electromechanical lock with automatic status control

    The system is not limited to simple electrical latch release. It features automatic lock status monitoring, incorrect operation correction and automatic relocking. This allows the lock to be used in residential buildings, offices, commercial premises and other access control systems.

    Operating principle

    Status Lock operation Result
    Locked The mechanism keeps the lock bolt in the locked position. The door remains locked.
    Unlock signal received The electromechanical mechanism releases the lock. The door can be opened.
    Door is not opened After approximately 5–8 seconds, the lock automatically returns to the locked state. Reduces the possibility of accidentally leaving the door unlocked.
    Manual operation The lock has one mechanical cylinder. Mechanical door operation is possible according to the installed lock configuration.

    Automatic locking function

    Automatic return to the locked state within 5–8 seconds

    If the lock is unlocked but the door is not opened, the lock automatically relocks after approximately 5–8 seconds. This function is particularly useful for shared entrances where it is important that the door does not remain unlocked after an unused unlocking signal.

    Suitable for different door opening directions

    Suitable for left- and right-hand doors and for doors opening inward or outward. This provides greater installation flexibility for entrances with different door configurations.

    The door construction must be checked before installation

    Although the lock mechanism is designed for different door opening directions, the specific door, frame, installation position, lock bolt position and the supplied strike plate must be evaluated before installation.

    Construction and main components

    Component Parameter Purpose
    Lock body Iron Forms the main mechanical structure of the lock.

    Integration with intercom and access control systems

    The lock can be used as an electrically controlled door lock together with a compatible intercom, access control, relay or door control system. When an unlocking signal is received, the lock releases the mechanical mechanism, allowing the door to be opened.

    Low standby current

    The manufacturer's catalogue specifies approximately 25mA standby current and an unlocking current of less than 350mA. These parameters allow the lock to be integrated into a properly selected low-voltage door control power supply system.

    Automatic lock status monitoring

    The electromechanical lock features automatic lock status monitoring and correction of incorrect mechanism operation. This helps ensure that the mechanism returns to its intended operating position after use.

    Advantages

    • Automatic locking after approximately 5–8 seconds if the door is not opened after unlocking.
    • Fast unlocking – the manufacturer's catalogue specifies an operating time of less than 1 second.
    • Single mechanical cylinder for additional mechanical operation.
    • Suitable for left- and right-hand doors.
    • Suitable for inward- and outward-opening doors.
    • Compatible with intercom and access control systems.
    • 25mA standby current reduces continuous power consumption.
    • More than 500,000 cycles declared mechanism service life.
    • Iron body and lock bolt provide a robust mechanical construction.
    • Nickel-plated finish provides the metal body with a neat finished surface.

    Limitations

    • External power supply required: the lock is not a standalone battery-powered version.
    • Mechanical installation required: the position of the lock and strike plate must be properly aligned.

    Suitable for

    • Entrance doors of apartment buildings and residential properties
    • Office doors
    • Commercial premises entrances
    • Intercom systems
    • Access control systems
    • Doors controlled by a relay unlocking signal
    • Left- and right-hand doors
    • Inward- or outward-opening doors

    Not suitable for

    • Standalone operation without an electrical power supply
    • Systems without a suitable 12V DC class power supply
    • Doors whose construction does not allow proper alignment of the lock and strike plate

    Practical application example

    The lock is installed on an office or apartment building entrance door and connected to a 12V DC power supply and an intercom or access control controller. When the user presses the unlock button, the controller sends a signal to the lock and the electromechanical mechanism releases the door in less than 1 second. If the door is not opened after unlocking, the lock automatically returns to the locked state after approximately 5–8 seconds.

    Important installation and electrical safety note

    The lock must be installed so that the lock body, bolt and strike plate are precisely aligned and operate without mechanical obstruction. The power supply must match the lock voltage and provide the required unlocking current. A 12V DC power supply is recommended for nominal operation. When integrating the lock into an intercom or access control system, the controller relay output, power supply and the electrical configuration of the entire system must be checked.
