The Apollo ASP-RI2M and ASP-RI4 are Apollo’s latest reader interface and door interface modules, designed to expand your access control system with both cost-efficiency and robust security. These advanced downstream panels communicate over encrypted channels and support both Wiegand and OSDP reader protocols. Equipped with onboard hardware interfaces, they allow seamless integration of door accessories and readers. A key feature is their downloadability—each panel stores its own configuration and data locally, enabling full access control functionality even when the main system is offline.
