SDC LR100ARK Electric Latch Retraction Kit | For Adams Rite 3000 & 8000 Series

The SDC LR100ARK is a high-efficiency Electric Latch Retraction (ELR) kit engineered to motorize your existing Adams Rite mechanical exit devices. This field-installable retrofit kit is the premier solution for commercial door security, allowing facility managers to integrate electronic access control and remote dogging without the high cost of replacing architectural-grade panic hardware. By converting your manual bar into a motorized system, the LR100ARK serves as a cost-effective solution for door restoration in high-traffic retail storefronts, office buildings, and aluminum storefront applications.

Motorized Access Control for Adams Rite Hardware

The SDC LR100ARK utilizes a quiet, high-torque motor to provide a modern, reliable alternative to traditional solenoid-driven kits. It acts as a proactive solution for door surface repair by reducing the mechanical stress and noise associated with manual operation:

• Adams Rite Device Compatibility: Precision-engineered for a wide range of models, including Rim (3700, 8700, 8800), Surface Vertical Rod (3100, 8100, 8200), and Concealed Vertical Rod (3600, 8600) series.
  
• Energy-Efficient Performance: Features an ultra-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.
  
• Sustained Electric Dogging: Ideal for daytime business hours, the motor can retract the latch for extended periods via an access control schedule, enabling "push-pull" operation while maintaining code-compliant uninhibited egress for life safety.
  
• Intelligent Re-Trigger Technology: The onboard logic 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 with the SDC LR100ARK provides a high-value solution for door restoration with professional-grade performance:

• Eliminate Costly Replacements: Retain your high-quality Adams Rite hardware and its structural thru bolts, significantly lowering material costs compared to purchasing entirely new electronic panic bars.
• Simplified Wiring Infrastructure: The low current requirement allows for longer wire runs using smaller gauge wire, providing more flexibility for installers and reducing overall project costs.
• 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.
