RDPS Vertiv Access Control Module | Door Contact Input, Security

Extend door-status monitoring with the Vertiv RDPS modular input module. Built with two door contact inputs, it gives security teams a simple way to bring additional openings into an access control system without overcomplicating the panel design. Because door switches are not included, the module is suited to deployments where field devices are already specified or standardized across a site. This is the kind of component that matters in larger environments: it keeps the control layer focused on signal handling while leaving the choice of contact hardware to the installer. That separation helps reduce rework during commissioning and makes it easier to align with existing door hardware standards. For teams managing multiple openings, the RDPS supports cleaner status reporting and a more disciplined access control architecture. Use it where reliable door contact input is needed and the system design calls for modular expansion rather than a full controller replacement. For procurement teams, it represents a targeted add-on that fills a specific gap without paying for unused capability.
