Smart electromechanical door lock | latch | with feedback signal | 12V DC | automatic locking | unlocks when power is applied

This version combines two key functions: two mechanical cylinders for mechanical unlocking with a key and a feedback signal for transmitting door / lock status to an access control system or other compatible controller. This allows the system not only to send an unlock command but also to receive information about the actual door status.

A Fail Secure lock remains locked in its normal state. When an electrical unlock signal is applied, the electromechanical mechanism releases the lock and allows the door to be opened. If the power supply is interrupted or no unlock signal is present, the mechanism remains locked.

The lock has an automatic relocking function. If the door is not opened after unlocking, the mechanism returns to the locked state after approximately 5–8 seconds.

This version includes an additional status feedback function. It is designed to transmit information about the door or lock status to a compatible access control or door control system. This allows the controller not only to send an unlock command but also to monitor whether the door / lock is in the expected position.

The unlock signal is sent from the controller to the lock and activates unlocking. The feedback signal transmits information from the lock / door back to the control system.

• Two mechanical cylinders provide the option of mechanical unlocking with a key.
• Status feedback signal allows the door / lock status to be transmitted to a compatible control system.
• Fail Secure operation – without unlocking power, the lock remains locked.
• Automatic relocking after approximately 5–8 seconds if the door is not opened after unlocking.
• Unlocking time <1s allows the lock mechanism to be released quickly.
• Suitable for left- and right-handed doors.
• Suitable for inward- and outward-opening doors.
• Compatible with intercom and access control systems.
• 25mA standby current provides low power consumption in standby mode.
• More than 500,000 cycles declared mechanism service life.
• Iron body and lock bolt provide a robust mechanical construction.

• An external power supply is required for electrical unlocking.
• The feedback function requires a compatible controller input: a basic intercom system may not necessarily be able to use the feedback signal.
• More complex wiring: using status feedback requires an additional signal connection.
• Fail Secure design: without unlocking power, the door does not unlock automatically.

On an office entrance door, the lock is connected to a 12V DC power supply and an access control controller. When access is granted, the controller sends an unlock signal and the electromechanical mechanism releases the lock in less than 1 second. At the same time, the status feedback signal allows the controller to monitor the door or lock status. If the door is not opened after unlocking, the lock automatically returns to the locked state after approximately 5–8 seconds. If required, it can also be operated mechanically with a key.

Yes. The lock has two mechanical cylinders and is designed to allow mechanical operation with a key.

It means that without unlocking power, the lock remains locked. When an electrical unlock signal is applied, the mechanism releases the lock.

It is a signal used to transmit information about the door or lock status back to a compatible access control or other control system.

No. The unlock command and status feedback signal are separate functions. The unlock signal controls the lock, while the feedback signal transmits status information to the controller.

12V DC is recommended for rated operation.

The unlocking current is less than 350mA.

The standby current is approximately 25mA.

The unlocking time is less than 1 second.

Yes. If the door is not opened after unlocking, the lock automatically returns to the locked state after approximately 5–8 seconds.

The lock body dimensions are 130x105x39mm.

The operating temperature range is from -20°C to +50°C.

More than 500,000 operating cycles.

The lock must be installed so that the body, lock bolt and strike plate are precisely aligned and operate without mechanical binding. The power supply must provide a stable 12V DC supply and sufficient unlocking current. The status feedback wiring must be connected according to the specific lock and controller wiring diagram. As this is a Fail Secure design, the lock remains locked when unlocking power is unavailable. Therefore, before installation on emergency exits, evacuation routes or other special-purpose doors, the safety requirements of the specific system must be evaluated.
