SDC LR100DHK QuietDuo Retrofit Motorized Latch Retraction Kit for Design Hardware 1000 and Trudoor TDE-1000 Series Exit Devices

SDC LR100DHK QuietDuo Retrofit Motorized Latch Retraction Kit for Design Hardware 1000 and Trudoor TDE-1000 Series Exit Devices (Field Installation)

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.
