Security Door Controls

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.

Features:

• Motorized electric latch retraction and dogging
• Panic and fire rated devices
• Simultaneous latch retraction, dogging and pushpad depression. Select models do not retract pushpad, only retract the latch.
• High traffic use
• Low current draw
• Low energy operator compatible

Models:

• LR100: Motorized electric latch retraction kit
• LR100-EM: Motorized electric latch retraction kit, external module

Applications:

• SDC’s retrofit motorized electric latch retraction kits are designed to be field installed. However, SDC also offers to install the kit at SDC’s factory. Simply send the mechanical exit device brand of your choice to SDC for factory install. The table below outlines exit device combability and part numbers for both field install and factory installed LR100 kits.
