Serial I/O Controller Authentic Mercury MR serial Input/output (SIO) devices represent the secondary level in Mercury’s distributed architecture. The devices offer flexibility for our OEM partners, ensuring they can choose the controller that best fits their needs. The MR51e is a single-door, network-ready and edgecapable interface panel that provides specific door oversight, point control and monitoring in a single device. It is an ideal integration solution when a direct network connection to a single door is required. The economical, high-performance device is compact and is easy to install anywhere. It also provides the I/O needed with PoE for complete door functionality. Features • • • • • • • Multi-facility code support PoE enabled Auto-addressable AES 128 bit data encryption HSPD-12/FIPS201 compliant UL 294 recognized Universal I/O device characterization Benefits • • • • Economical Network enabled and web configured, providing greater flexibility to installers Highly adaptable to a variety of sensors and reader technologies Supports OSDP, Wiegand, clock and data, magnetic stripe, F2F, Supervised F2F, keypads, LCD and biometrics www.mercury-security.com Two reader ports support separate in/out readers and a range of reader technologies: OSDP, Wiegand, clock and data, magnetic stripe, keypads, LCD and biometrics. Autoaddressable and directly managed by the Authentic Mercury intelligent controllers, the MR51e is capable of elaborate processes and procedures without host intervention. Application Notes The MR51e can relate the activities of selected system devices to other devices within the system, generating actions and allowing activities to occur independent of the host. The MR51e supports paired readers to enhance its ability to meet installation challenges, such as placing readers at varying heights or distances (to accommodate ingress and egress of handicapped, vehicle and/or foot traffic). These readers can be logically linked together but function independently when a credential is presented to either one. When access rights are granted, the same relay will function, as programmed, to unlock the opening. Give your access control system wings.
