The SDC - SECURITY DOOR CONTROLS LR100FCK is a First Choice ELR Kit designed for use as a panel accessory in access control and door security systems. This kit provides the components necessary to enable electric latch retraction functionality, allowing a door latch to retract via an electrical signal rather than manual operation. It is typically installed by licensed electricians or security system integrators working on commercial door hardware and access control panel builds.
The LR100FCK is suited for commercial access control installations where electric latch retraction is required at the panel level. It is used in scenarios where controlled egress or remote latch operation must be integrated into an existing or new security panel configuration. Installation is performed by security hardware professionals and low-voltage electricians in commercial and institutional settings.
Designed as an OEM-style panel accessory kit for commercial access control and electric latch retraction systems. Consult the product manual and SDC documentation to confirm compatibility with specific panel configurations before installation.
Installation of the LR100FCK should be performed by a licensed electrician or qualified security system integrator familiar with low-voltage access control wiring. De-energize the panel and disconnect all power sources before beginning any wiring or component work. Follow all applicable local electrical codes and the manufacturer product manual for wiring and mounting guidance. Do not energize the system until all connections have been inspected and verified.
