Security Door Controls LRVD1R Request-to-Exit (REX) is a sophisticated retrofit monitoring kit designed for Von Duprin exit devices, including models 98, 99, 33, and 35. This innovative solution enables seamless electric access control and dogging for both panic and fire-rated mechanical exit devices. Upon activation, the motor retracts the latch, allowing for momentary or sustained push and pull operation of the door, ensuring unhindered egress at all times. The LRVD1R's motorized electric latch retraction offers numerous advantages over traditional solenoids, including reduced current draw, quieter operation, and enhanced longevity. With a current draw of only 200 mA in continuous use, this kit is compatible with low energy operators, making it ideal for high-traffic areas. The design of the LRVD1R also emphasizes cost-effectiveness, eliminating the need for expensive replacements by retrofitting existing exit devices without the hassle of removal. Installation options include field installation or factory installation by SDC, enhancing flexibility for building professionals. Incorporating the latest in electric latch retraction technology, the Security Door Controls LRVD1R is the choice for those seeking reliable, efficient, and durable access control solutions.
Request-to-Exit (REX), Von Duprin Retrofit Monitoring Kit, 98/99/33/35 Exits
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.
