Łucznik 822-12AC/DC Symmetrical Electric Strike, NC, Adjustable with Mechanical Switch

The Łucznik 822-12AC/DC is a high-quality symmetrical electric strike engineered for professional access control systems. This device operates in a normally closed (NC) mode, meaning it remains locked when powered off and releases only when an electrical signal is received. Its symmetrical design ensures universal compatibility with both left-hand and right-hand doors, making it a versatile choice for various installation environments.

Advantages

The primary benefit of this electric strike is its robust construction and reliable performance in demanding security applications. The inclusion of an adjustable latch allows for precise alignment with the door lock, ensuring smooth operation and reducing mechanical wear over time. Furthermore, the integrated mechanical switch provides a convenient manual unlocking feature, allowing users to keep the door permanently open when necessary without requiring constant electrical activation.

Suitable for

• Residential apartment building intercom systems
• Office access control and security doors
• Integration with electronic entry systems
• Doors requiring manual override functionality

This electric strike may not be suitable for high-security applications requiring fail-safe (normally open) operation, as this model is designed to remain locked during power failures. It is also not intended for use on heavy-duty industrial gates or doors that require specific fire-rated hardware certifications not covered by this standard electric strike.

Key specifications

• Operating voltage: 12V AC/DC
• Mode: Normally Closed (NC)
• Design: Symmetrical
• Features: Adjustable latch, mechanical manual unlock switch

To install the Łucznik 822-12AC/DC, ensure the door frame is prepared to accommodate the strike dimensions. Connect the device to a compatible 12V power supply integrated with your intercom or access control system. Once mounted, use the adjustable latch feature to fine-tune the engagement with the door bolt to prevent rattling or binding. The mechanical switch can be toggled manually to bypass the electronic locking mechanism when temporary free access is required.

What to consider before purchase

• Verify that your existing power supply provides 12V AC or DC
• Confirm that your door setup supports a symmetrical strike configuration
• Check if the normally closed (NC) operation meets your building's security requirements

For optimal longevity and performance, ensure the electric strike is kept clean from debris and that the door alignment is maintained regularly to prevent excessive pressure on the latch mechanism.
