## Summary description

The Łucznik 1720-12AC/DC is a symmetrical electric strike designed for access control systems. It operates in NC (normally closed) mode and features a built-in mechanical switch for manual unlocking. Compatible with 12V AC/DC power supply, this strike is suitable for various door types, providing reliable security and convenient entry management in residential and commercial installations.

## Long description

The Łucznik 1720-12AC/DC is a high-quality symmetrical electric strike engineered for integration into modern access control systems. Designed to provide reliable door locking, this device operates in a normally closed (NC) configuration, ensuring that the door remains locked when power is absent. The inclusion of a built-in mechanical switch allows for manual unlocking, offering flexibility in how access is managed throughout the day. Its symmetrical design simplifies installation on both left and right-handed doors, making it a versatile choice for various door frames.
Advantages
The primary benefit of this electric strike is its dual-voltage compatibility, supporting both 12V AC and DC power sources, which allows for seamless integration with a wide range of existing intercom and access control hardware. The symmetrical construction significantly reduces installation time and complexity, as it eliminates the need to choose a specific handing during the planning phase. Furthermore, the integrated mechanical switch provides a practical solution for scenarios requiring temporary free access without the need to keep the system powered, enhancing the overall functionality of the entry point.
Suitable for
Residential apartment building entrance doors
Office doors requiring controlled access
Gates and wicket doors in private properties
Integration with intercom and video door phone systems
This electric strike may not be suitable for doors that require a fail-safe (normally open) configuration, as this model is strictly normally closed. It is also not intended for use on heavy-duty industrial fire doors or emergency exit doors that must comply with specific life-safety regulations requiring panic hardware.
Key specifications
Operating mode: Normally Closed (NC)
Power supply: 12V AC/DC
Design: Symmetrical
Manual unlocking: Integrated mechanical switch
Compatibility: Standard door frames
To use the Łucznik 1720-12AC/DC, ensure it is correctly mounted within the door frame strike plate area. Connect the device to a compatible 12V power supply unit controlled by your access system. Once installed, the strike will remain locked until an electrical impulse is received or the manual mechanical switch is toggled to the open position, allowing the latch to move freely.
What to consider before purchase
Verify that your access control system supports a normally closed (NC) strike.
Ensure your power supply provides a stable 12V AC or DC output.
Check the dimensions of your existing door strike plate to ensure compatibility.
For optimal performance and longevity, ensure the electric strike is protected from direct exposure to harsh weather conditions and that the door is properly aligned to prevent excessive pressure on the strike mechanism.
