Suitable for various door types, this reliable strike ensures secure and efficient operation in residential and commercial security installations.

## Long description

The Łucznik 1433-12AC/DC is a high-quality symmetrical electric strike engineered for integration into modern access control systems. This device operates in a normally closed (NC) configuration, meaning it remains locked when powered off and unlocks when an electrical signal is received. A standout feature of this model is its integrated internal memory, which allows the strike to remain in an unlocked state after receiving a single short electrical pulse. The mechanism stays open until the door is physically opened and subsequently closed, providing convenience for users entering a premises.
Advantages
The symmetrical design of this electric strike ensures universal compatibility, allowing for easy installation on both left-handed and right-handed doors without the need for complex modifications. Its robust construction guarantees long-term reliability in various environmental conditions, making it an ideal choice for both residential buildings and commercial office spaces. The internal memory function significantly improves user experience by eliminating the need to maintain constant pressure on an intercom button or access control reader, as a brief signal is sufficient to grant entry.
Suitable for
Residential apartment building entrance doors
Office building access control systems
Integration with intercom and video door phone systems
Internal doors requiring secure electronic locking
This electric strike may not be suitable for high-security applications where a fail-safe (normally open) mechanism is required by fire safety regulations. Additionally, it is not intended for outdoor installations exposed to direct precipitation or extreme weather conditions without appropriate protective housing.
Key specifications
Operating voltage: 12V AC/DC
Mode of operation: Normally Closed (NC)
Integrated internal memory function
Symmetrical housing design
Suitable for various door frame profiles
To use the electric strike, connect it to your existing access control system or intercom power supply according to the wiring diagram provided by your system manufacturer. Once installed, the device will remain locked under normal conditions. When a signal is sent from your control unit, the internal memory mechanism releases the latch, allowing the door to be opened. The strike will automatically reset to the locked position once the door has been opened and closed again.
What to consider before purchase
Verify that your power supply provides 12V AC or DC
Check if your door frame has sufficient space for a symmetrical strike
Ensure that the NC (normally closed) operation meets your security requirements
Confirm compatibility with your existing intercom or access control hardware
For optimal performance and longevity, ensure that the door is properly aligned with the frame to prevent excessive pressure on the strike mechanism. Regular inspection of the electrical connections is recommended to maintain consistent operation.
