SDC LR100SGK Electric Latch Retraction Kit | For Sargent 8000 Series Devices

The SDC LR100SGK is a high-performance Electric Latch Retraction (ELR) kit specifically engineered to motorize existing Sargent 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 LR100SGK serves as an efficient solution for door restoration in high-traffic schools, hospitals, and government buildings.

Motorized Access Control for Sargent Hardware

The SDC LR100SGK 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 on the latching mechanism:

• Sargent Device Compatibility: Precision-engineered for the Sargent 8800 Rim, 8700 Surface Vertical Rod (SVR), and 8600 Concealed Vertical Rod (CVR) series.
  
• Streamlined Retrofit Design: On non-fire rated Sargent panic devices, this kit can be installed without even removing the device from the door, significantly reducing downtime and labor costs.
  
• Sustained Electric Dogging: Perfect for high-traffic daytime business hours, the motor can hold the latch 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 accessible.
  

Energy-Efficient Performance and Installation Benefits

Upgrading your facility to electronic locks with the SDC LR100SGK 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 specialized high-inrush power supplies—a standard 1 Amp power supply can successfully handle up to two exit devices.
  
• Cost-Effective Retrofitting: Retain your high-quality Sargent hardware and its structural thru bolts, significantly lowering material costs compared to purchasing entirely new electronic panic bars.
• 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.
• Simplified Wiring: The low current requirement allows for longer wire runs with smaller gauge wire, providing more flexibility for installers during a solution for door restoration project.
