SDC LR100DXK Electric Latch Retraction Kit | For Detex 10/40 & 20/50 Series

The SDC LR100DXK is a high-performance Electric Latch Retraction (ELR) kit specifically engineered to motorize existing Detex mechanical exit devices. This field-installable retrofit kit is the premier solution for commercial door security, allowing for seamless integration with access control systems without the high cost of replacing heavy-duty architectural hardware. By converting your manual panic bar into a motorized system, the LR100DXK serves as a cost-effective solution for door restoration in high-traffic schools, healthcare facilities, and industrial warehouses.

Motorized Access Control for Detex Hardware

The SDC LR100DXK utilizes a quiet, high-torque motor to provide a modern alternative to traditional, noisy solenoid-driven kits. It acts as a proactive solution for door surface repair by reducing mechanical impact and wear:

• Extensive Detex Compatibility: Precision-engineered for Detex 10 Series & 40 Series Rim devices, 20 Series & 50 Series Surface Vertical Rod (SVR), and 62/63 & 81/82 Series Concealed Vertical Rod (CVR).
  
• Simultaneous Latch & Pushpad Retraction: The LR100DXK pulls the pushpad into the dogged (depressed) position while retracting the latch. This ensures a much quieter "push-pull" operation, making it an ideal solution for door restoration in noise-sensitive corridors and office environments.
  
• Sustained Electric Dogging: Perfect for high-traffic daytime use, the motor can hold the door in a retracted state via an access control schedule or remote switch, while always maintaining code-compliant uninhibited egress for life safety.
• Intelligent Re-Trigger Technology: The onboard logic includes an automatic re-trigger function; if the device fails to retract on the first attempt, the motor automatically pulses again to ensure the door is unlocked and accessible.
  

Energy-Efficient Performance and Installation Benefits

Upgrading your facility to electronic locks with the SDC LR100DXK provides a streamlined solution for commercial door security with optimized power requirements:

• Low Current Infrastructure: Features a remarkably low 700 mA inrush and a quiet 200 mA continuous hold at 24VDC. This efficiency eliminates the need for expensive, high-inrush power supplies—a standard 1 Amp power supply can successfully handle up to two exit devices.
  
• Extended Wire Runs: The low current requirement allows for longer wire runs using smaller gauge wire, significantly reducing material costs and labor during your solution for door restoration project.
• Fire-Rated Safety Compliance: This kit is UL Classified for use with 3-hour fire-rated and non-fire-rated exit devices, ensuring your building remains fully compliant with life safety regulations.
• No Door Sequencers Required: Simplifies the installation process for pairs of manual doors, reducing the amount of additional hardware needed for a complete opening.
