## Long description

The Łucznik 1420RF-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, ensuring security for your premises. It is designed to work seamlessly with 12V AC/DC power supplies, making it a versatile choice for various installation environments. The inclusion of a mechanical switch allows for manual unlocking, providing flexibility in how you manage entry and exit points in both residential and commercial buildings.
Advantages
The symmetrical design of this electric strike simplifies the installation process, as it can be mounted on both left and right-handed doors without requiring complex modifications. Its robust construction ensures long-term reliability and resistance to mechanical wear, which is essential for high-traffic areas. The integrated mechanical switch offers a practical override feature, allowing users to keep the door permanently unlocked when needed, such as during business hours or specific events. Furthermore, the compatibility with both alternating and direct current power sources provides significant flexibility for system integrators and installers.
Suitable for
Residential apartment building entrance doors
Office building access control systems
Internal doors in commercial facilities
Gates and wicket doors requiring remote locking
When it may not be suitable
This electric strike is not intended for use on fire-rated doors where specific safety certifications are required for emergency egress. Additionally, it is not suitable for outdoor environments exposed to direct, harsh weather conditions without proper protective housing, as moisture may affect the internal electrical components.

How to use
To install the Łucznik 1420RF-12AC/DC, ensure the door frame is prepared to accommodate the strike dimensions. Connect the device to a compatible 12V power supply unit. Once installed, the strike will remain locked by default. When an electrical pulse is sent from your access control system, such as an intercom or keypad, the strike will release, allowing the door to be opened. The mechanical switch located on the strike can be toggled manually to keep the latch in an open position, bypassing the electrical locking mechanism until it is manually reset.
What to consider before purchase
Verify the voltage requirements of your existing access control system
Check the door frame material to ensure compatibility with the strike mounting
Confirm if your local regulations allow for the use of NC strikes in your specific building type
Assess whether the manual mechanical switch is accessible for your intended installation height
Usage recommendations: For optimal performance and longevity, ensure that the door is properly aligned with the strike plate to prevent unnecessary pressure on the locking mechanism. Regularly inspect the mechanical switch for debris and ensure that electrical connections remain tight and free from corrosion.
