Security Door Controls LR100-VDK QuietDuo Retrofit Motorized Electric Latch Retraction Kit for Von Duprin 98/99

Security Door Controls LR100-VDK QuietDuo is a sophisticated retrofit motorized electric latch retraction (ELR) kit designed to enhance access control for Von Duprin 98/99 exits with openings ranging from 36 inches to 48 inches. This innovative kit allows for seamless integration with panic and fire-rated mechanical exit devices, enabling both momentary and sustained push and pull operations through its efficient motorized retraction mechanism. The LR100-VDK operates on a 24 VDC power supply, drawing only 1.5 amps during inrush and 200 mA continuously, making it both energy-efficient and cost-effective. It eliminates the need for costly replacements of existing exit devices while significantly reducing installation time and labor costs compared to competitor models. Notably, the LR100 series is engineered for high-traffic use and is compatible with various exit device brands, ensuring a versatile solution for your security needs. Its patented design provides quieter operation and increased durability, positioning it as a leader in the market since its inception. The device guarantees uninhibited egress, making it ideal for use in commercial and residential settings. Enhance your security infrastructure with the reliability and efficiency of the Security Door Controls LR100-VDK QuietDuo kit.

QuietDuo, Retrofit Motorized Electric Latch Retraction (ELR) Kit, Von Duprin Field Install Kit for 98/99 Exits, 36in to 48in Opening

SDC’s QuietDuo LR100 series retrofit electric latch retraction kits enable electric access control and dogging of panic and fire rated mechanical exit devices. When energized the motor retracts the exit device latch and pulls the pushpad into the dogged (depressed) position enabling momentary or sustained push and pull operation of the door. The latch retraction mechanism may be activated by an access control, remote control device or building automation system. No door sequencer required for a pair of manual doors when connected to a suitable power supply. The exit device always provides uninhibited egress. The patented design was the first retrofit motorized electric latch retraction kit brought to market and has been recognized as the market leader ever since. The use of a motorized electric latch retraction device provides several advantages over solenoids including lower current draw, quieter operation and greater durability over time. Designed with cost savings in mind, SDC’s LR100 series retrofit ELR kits not only eliminate the need for costly replacements of existing exit devices, but also provide cost savings on installation and power requirements due to significantly less labor time and current draw when compared to competitive retrofit kits. LR100 kits retrofit select exit device brands without removing the device from the door. LR100 models are one unit completely housed within the rail of the device behind the access cover, whereas LR100-EM models are two piece space saver units, intended to gain up to one inch in spacing within the device, placing the controller board externally to accommodate smaller field cut devices for smaller openings or where space is limited within the rail.
