SDC LRVD1R REX Status Controller
Overview
The LRVD1R is a networked REX (request-to-exit) status controller purpose-built for multi-door access control systems. It solves the integration problem when your Von Duprin 98/99-series hardware needs centralized event logging and real-time exit monitoring across a distributed facility. Deploy this when compliance-driven environments require documented proof that each door's egress state is being monitored and logged — a critical requirement in healthcare, financial, and secure facility deployments.
Compatibility
The LRVD1R integrates with Von Duprin 98/99-33 series exit devices. It works within OSDP-compliant access control panels and IP-networked environments, supporting credential formats including DESFire, MIFARE, NFC (13.56 MHz), and 125 kHz proximity — meaning it fits mixed-credential deployments without forklift replacement. Verify your existing panel infrastructure supports OSDP and TCP/IP protocols before specifying; compatibility confirmation during design phase prevents field discovery issues.
Installation Notes
The LRVD1R handles up to 63 doors and 250,000 user credentials in a single controller, reducing panel count in mid-to-large facilities. Wiring runs via standard TCP/IP network infrastructure — no separate serial lines required if your access control network is already IP-deployed. Confirm your network switch can handle the combined load of all readers and exit monitoring traffic; most modern managed switches handle this transparently, but oversubscribed PoE budgets are a common field gotcha. The controller integrates into OSDP-compliant VMS platforms; test with your specific panel firmware revision during pre-deployment staging.
