SDC LR100HK QuietDuo LR100 Series Hager Field Install Retrofit Electric Latch Retraction Kit, 4501, 36" 48" Opening

Enable electric access control without replacing proven exit hardware. The Security Door Controls QuietDuo LR100HK field retrofit latch retraction kit is designed to convert Hager 4500 series exit devices for electric latch retraction and sustained dogging, giving facilities reliable remote control and streamlined traffic flow. The LR100HK operates on 24V DC with a 700 mA inrush and just 200 mA continuous draw, keeping power requirements low for access control panels and building automation systems. Installation is optimized for common 36" and 48" openings and supports activation via access control, remote triggers or integrated building monitoring platforms. Because the exit device always provides uninhibited egress, the LR100HK meets life-safety expectations while adding functionality for security and surveillance integrations. Ideal for retrofits in schools, healthcare, commercial and government facilities, this retrofit kit reduces downtime and installation cost compared to full device replacement. Specify the SDC LR100HK for your next access control or retrofit project to add electric latch retraction with proven safety — contact your distributor or systems integrator to order.

• Retrofit-ready kit converts mechanical Hager 4500 series exit devices to electric latch retraction without replacing the device
• Enables electric access control and sustained dogging for easier traffic flow and remote monitoring
• Low continuous draw (200 mA at 24V DC) with 700 mA inrush minimizes power budget and supports building automation systems
• Preserves life-safety egress: exit device always allows uninhibited egress while providing momentary or sustained push/pull operation
• Simple field install for 36" and 48" openings reduces installation time and avoids costly door hardware replacement
