SDC LR100VDK-22 Electric Latch Retraction Kit | For Von Duprin 22 Series

The SDC LR100VDK-22 is a high-performance Electric Latch Retraction (ELR) kit precision-engineered to motorize your existing Von Duprin 22 Series mechanical exit devices. This field-installable retrofit kit is the premier solution for commercial door security, allowing facility managers to integrate electronic access control without the excessive cost of replacing architectural-grade panic hardware. By converting your manual bar into a motorized system, the LR100VDK-22 serves as a cost-effective solution for door restoration in high-traffic schools, healthcare facilities, and commercial office buildings.

Motorized Access Control for Von Duprin 22 Series Hardware

The SDC LR100VDK-22 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 the physical impact and mechanical wear associated with manual operation:

• Von Duprin 22 Series Compatibility: Precision-engineered specifically for the Von Duprin 22 Series Rim and 2227 Surface Vertical Rod (SVR) exit devices.
  
• Simultaneous Latch & Pushpad Retraction: The LR100VDK-22 pulls the pushpad into the dogged (depressed) position while retracting the latch. This results in much quieter "push-pull" operation, making it an ideal solution for door restoration in noise-sensitive environments like libraries or healthcare corridors.
  
• Sustained Electric Dogging: Perfect for high-traffic daytime use, the motor can hold the door in a retracted state via an access control schedule, 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 ready for use.
  

Energy-Efficient Performance and Installation Benefits

Upgrading your facility to electronic locks doesn't have to involve a massive infrastructure overhaul. The SDC LR100VDK-22 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.
  
• Simplified Retrofitting: This kit is designed to be installed in non-fire rated panic devices without even removing the device from the door. It integrates perfectly with existing thru bolts for maximum stability.
  
• 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.
  
• 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.
