About the LR100FCK

Convert compatible mechanical exit devices for electric access control with the LR100FCK field-install retrofit kit. When energized, its motor retracts the latch and depresses the pushpad, enabling momentary or sustained push-and-pull operation. Activation can be connected to an access control, remote control device, or building automation system, while the exit device maintains uninhibited egress.

Designed for compatible 3790/3690 devices on 36-inch openings, this kit supports panic- and fire-rated applications. Features include simultaneous latch retraction and pushpad depression, quiet operation, suitability for high-traffic use, low current draw, and compatibility with low-energy operators.
