SDC LR100CRK Electric Latch Retraction Kit | For Corbin Russwin ED Series Exit Devices

The SDC LR100CRK is a high-performance Electric Latch Retraction (ELR) kit engineered to motorize existing Corbin Russwin mechanical exit devices. This field-installable retrofit solution is a premier solution for commercial door security, allowing facility managers to integrate electronic access control without the expense of replacing architectural-grade panic hardware. By converting your manual bar into a motorized system, the LR100CRK serves as an efficient solution for door restoration in high-traffic schools, hospitals, and government buildings.

Motorized Access Control for Corbin Russwin Hardware

The SDC LR100CRK utilizes a quiet, high-torque motor to retract the latch, providing a modern alternative to noisy solenoid kits. It acts as a proactive solution for door surface repair by reducing the mechanical impact and wear associated with manual operation:

• Corbin Russwin Device Compatibility: Specifically designed for the ED4200 and ED5200 Rim devices, ED5400 Surface Vertical Rod (SVR), and ED5800 Concealed Vertical Rod (CVR) series.
• Energy-Efficient Performance: Boasts a remarkably low 700 mA inrush and a quiet 200 mA continuous hold. This low power requirement eliminates the need for expensive high-inrush power supplies, allowing for a more cost-effective solution for commercial door security.
• Sustained Electric Dogging: Perfect for high-traffic daytime use, the motor can hold the latch retracted for extended periods via an access control schedule, while always maintaining code-compliant uninhibited egress.
  
• Intelligent Re-Trigger Technology: The onboard circuitry includes an automatic re-trigger function; if the latch fails to retract on the first attempt, the motor automatically pulses again to ensure the door is unlocked.

Streamlined Retrofitting and Installation Benefits

Upgrading your facility to electronic locks doesn't have to be a labor-intensive overhaul. The SDC LR100CRK provides a high-value solution for door restoration with minimal downtime:

• Retention of Existing Hardware: Retain your high-quality Corbin Russwin exit devices and their specialized thru bolts, significantly lowering material costs compared to buying new electronic panic bars.
  
• Simplified Wiring Infrastructure: The low current draw allows for longer wire runs with smaller gauge wire, providing more flexibility for installers during a solution for door restoration project.
• Fire-Rated Compliance: This kit is UL Classified for use on 3-hour fire-rated and non-fire-rated exit devices, ensuring your building remains safe and up to code.
• Optional Monitoring Kits: Further enhance your security by adding the LRCR1L Latch Status Kit or the LRCR1R REX (Request-to-Exit) Status Kit for real-time feedback to your security system.
