SDC LRDX1R Detex Retrofit Monitoring Kit, 10/20/40/50/60/80, Request-To-Exit (REX)

Upgrade door monitoring and access control quickly with the Security Door Controls LRDX1R Detex Retrofit Monitoring Kit. This accessory kit converts existing Detex exit devices into monitored Request‑To‑Exit (REX) points, providing reliable door-status signals that integrate with access control panels, alarm systems, and surveillance platforms. Compatible with Detex models 10, 20, 40, 50, 60 and 80, the LRDX1R installs easily as a retrofit and runs on low-voltage DC power for seamless tie-in to building power and security infrastructure.

Designed for B2B deployments, the LRDX1R reduces installation time and lowers total cost by eliminating the need to replace functioning exit hardware. Facility managers gain clearer monitoring, fewer nuisance alarms, and better situational awareness for high-traffic egress points. Installers benefit from a compact, US-made kit (manufacturer part number LRDX1R) from Security Door Controls that delivers dependable performance in commercial, healthcare, education, and government settings.
