Security Door Controls LRVD2L Latch Status (LS) is a sophisticated retrofit monitoring kit designed for Von Duprin 33A and 35A exit devices. This innovative solution enables electric access control and dogging for panic and fire-rated mechanical exit devices, enhancing security while ensuring ease of operation. When energized, the LRVD2L retracts the latch and secures the pushpad in a depressed position, allowing for both momentary and sustained push and pull operation of the door. The motorized latch retraction mechanism is compatible with various access control systems, remote devices, or building automation setups, making it versatile for different environments. Notably, it requires no door sequencer for a pair of manual doors when connected to an appropriate power supply. The LRVD2L boasts lower current draw and quieter operation compared to traditional solenoid systems, ensuring durability and reliability over time. Its design not only reduces the need for costly replacements of existing exit devices but also minimizes installation costs and labor time. With a current draw of 1.5 Amp inrush and 200 mA continuous, this retrofit kit is both efficient and effective. Upgrade your security infrastructure with the Security Door Controls LRVD2L, where safety meets convenience.
Latch Status (LS), Von Duprin Retrofit Monitoring Kit, 33A/35A 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.
