The SDC LR100 Series Electric Latch Retraction Kit enables electric access control and dogging of mechanical exit devices. When energized the motor retracts the exit device latch and pulls the pushpad on most devices into the dogged (depressed) position enabling momentary or sustained push and pull operation of the door.

The SDC LR100FAK is an electric latch-retraction kit for access-control installations using compatible mechanical exit devices, enabling electrically controlled latch retraction and pushpad dogging.
Recommended For
- Commercial access-control installers adding remote or automated release to an existing 36-inch Dor-O-Matic 1790 rim exit device or 1690 concealed-vertical-rod exit device; the LR100FAK is the model-specific retrofit kit for those devices.
- Facility teams upgrading an existing commercial exit door for staff entry after hours, using an access-control system to trigger latch retraction rather than replacing the entire exit device.
- Building operators who want remote or scheduled latch retraction and pushpad dogging on compatible mechanical exit hardware, with activation from access control, a remote control, or building automation.
- Teams retaining a compatible panic or fire-rated exit device while adding controlled entry; SDC describes the LR100 series as a retrofit for mechanical exit devices that preserves uninhibited egress.
