Serial I/O Controller

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 MR52 is a dual-card reader interface panel with
on-board flexibility to connect to a wide range of security
devices. The economical MR52 is easy to install and
provides the necessary I/O for controlling two doors with
auxiliary point control and monitoring – all in a single device.
Each high-performance unit can connect two card readers,
eight general-purpose input monitor points and six control
relays to any Authentic Mercury EP series intelligent
controller.

With two-wire RS-485 connectivity, the MR52’s two reader
ports support OSDP, Wiegand, RS-485, and magnetic stripe
readers. Keypads and integrated keypad readers are also
supported. Hardware interface and card format settings are
loaded through software commands.
The MR52 is an ideal choice for a versatile and reliable
interface panel for two doors.
Application Notes
The inputs and the relays may be assigned to door-related
functions or to general purpose I/O. The inputs support
normally open, normally closed, supervised, and nonsupervised circuits. End-of-line (EOL) resistance values are
configurable, and the relays can be configured for fail-safe
or fail secure operation.
When connected to an Authentic Mercury EP intelligent
controller, the MR52 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 MR52 can also locally process
access requests based on facility code verification, even
when disconnected from an intelligent controller. Several
facility codes may be active in each MR52.
