Sdc LR100VDK-EM Von Duprin Elr Kit External Mod

Product Description

The SDC Security Door Controls LR100VDK-EM is an external modification kit designed to add electrified latch retraction (ELR) functionality to compatible Von Duprin exit devices. The kit allows an existing mechanical exit device to be upgraded in the field without full replacement, enabling the door to be held or released electrically as part of an access control or life safety system. Licensed locksmiths, access control technicians, and commercial door hardware specialists typically perform this installation. The LR100VDK-EM is sold as a single unit and is intended for professional installation in commercial door openings.

This kit is used in commercial and institutional settings where electrified hardware is required for integration with access control panels, fire alarm release systems, or building automation systems. It is applied externally to an existing Von Duprin exit device, making it suitable for retrofit projects where replacing the entire exit device is not practical. Typical installation scenarios include office buildings, schools, healthcare facilities, and any occupancy requiring electrically controlled egress.
