SDC LR100PDK Electric Latch Retraction Kit | For PHI Precision 2000 & 5000 Series

The SDC LR100PDK is a high-performance Electric Latch Retraction (ELR) kit engineered to motorize your existing PHI Precision 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 LR100PDK serves as a cost-effective solution for door restoration in high-traffic schools, healthcare facilities, and commercial office buildings.

Motorized Access Control for PHI Precision Hardware

The SDC LR100PDK 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:

• PHI Precision Compatibility: Precision-engineered specifically for the 2101 & 5100 Rim series, 2201 & 5200 Surface Vertical Rod (SVR), and 2801 Concealed Vertical Rod (CVR) exit devices.
• Simultaneous Latch & Pushpad Retraction: The LR100PDK 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 hospitals or libraries.
  
• 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 LR100PDK 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.
