The SDC - SECURITY DOOR CONTROLS LRCR1R is a Rex switch kit assembly designed for request-to-exit applications in access control systems. This kit provides the switching components needed to signal a door release when an occupant intends to exit a controlled door. It is compatible with Corbin Russwin hardware configurations and is typically installed by licensed locksmiths, security integrators, or low-voltage access control technicians working on commercial door systems.
The LRCR1R fits into request-to-exit installations where a door position or motion sensor triggers an egress signal to an access control panel. This type of assembly is commonly used in commercial and institutional buildings where controlled entry and compliant egress are required at the same door leaf.
Designed as an OEM-style replacement switch kit assembly for Corbin Russwin door hardware used in request-to-exit access control applications.
Installation is typically performed by a licensed locksmith or low-voltage access control technician. Disconnect power to the access control panel and any electrified hardware before beginning work. Follow applicable local codes and manufacturer wiring diagrams during integration with the door control system. Verify proper egress function after installation to confirm the request-to-exit signal operates as intended.
