## Summary description

The Łucznik 1443-12AC/DC is a symmetrical electric strike designed for access control systems. It features a normally closed (NC) operation, an integrated mechanical switch for manual unlocking, and internal memory functionality. This reliable strike is suitable for various door types, ensuring secure and efficient entry management in residential or commercial buildings.

## Long description

The Łucznik 1443-12AC/DC is a high-quality symmetrical electric strike engineered for professional access control systems. This device operates in a normally closed (NC) state, meaning the door remains locked when there is no power supply. It is equipped with an integrated mechanical switch that allows for manual unlocking, providing flexibility for daytime operations or specific access requirements. Additionally, the internal memory function ensures that a single electrical impulse is sufficient to keep the strike unlocked until the door is opened and closed again, enhancing convenience in high-traffic environments.
Advantages
The primary benefit of this electric strike is its symmetrical design, which simplifies installation on both left and right-handed doors, reducing the need for specialized hardware. The inclusion of a mechanical switch offers a practical manual override, allowing users to keep the door permanently unlocked without constant electrical input. The internal memory feature is particularly advantageous for intercom systems, as it eliminates the need to hold the release button until the door is physically pushed. Its compatibility with both AC and DC power sources makes it a versatile component for various security setups.
Suitable for
Residential apartment buildings and intercom systems
Commercial office doors requiring controlled access
Doors where manual override functionality is necessary
Systems where temporary unlocking via a single pulse is required
When it may not be suitable
This electric strike is not suitable for fire-rated doors or emergency exit routes that require fail-safe operation, as it is a normally closed device that remains locked during a power failure. It should not be used in environments where the door must automatically unlock in the event of a fire or power outage.
Key specifications
Operation mode: Normally Closed (NC)
Power supply: 12V AC/DC
Mechanical switch: Integrated for manual unlocking
Memory function: Internal
Design: Symmetrical
How to use
Installation should be performed by a qualified technician to ensure proper alignment with the door latch. The strike is mounted into the door frame, replacing the standard strike plate. Once installed, the electrical connections are made to the access control system or intercom. The mechanical switch can be toggled manually to set the strike to a permanently unlocked state when needed. For standard operation, the system will unlock momentarily upon receiving an electrical signal, or remain unlocked until the door is opened if the memory function is utilized.
What to consider before purchase
Verify that your door frame has sufficient space for the strike dimensions
Ensure your power supply unit provides 12V AC or DC
Confirm that the normally closed (NC) operation meets your security requirements
Check if your existing lock mechanism is compatible with a symmetrical strike
Usage recommendations
Regularly inspect the mechanical switch and the strike plate for debris or wear to ensure smooth operation. Ensure that the door is correctly adjusted so that the latch does not exert excessive pressure on the strike, which could prevent the mechanism from releasing properly.
