Mercury MR52 Series 2 & 3 Serial I/O Controllers

MR52

Authentic Mercury MR serial Input/output (SIO) devices represent the secondary level in Mercury’s distributed architecture. The MR52 Series 2 & 3 SIO are dual-card reader interface panel with onboard flexibility to connect to a wide range of security devices. The economical MR52 Series 2 & 3 SIO are easy to install and provides the necessary I/O for controlling two doors with auxiliary point control and monitoring – all in a single device.

The MR52 Series 2 & 3 SIO are dual-card reader interface panel with onboard flexibility to connect to a wide range of security devices. The economical MR52 Series 2 & 3 SIO are 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 Series 2 & 3 SIO are 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 Series 2 & 3 SIO are 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 non-supervised circuits. The relays can be configured for fail-safe or fail-secure operation.

When connected to an Authentic Mercury EP intelligent controller, the MR52 Series 2 & 3 SIO can relate the activities of selected system devices to other devices within the system, generating actions and allowing activities to occur independently of the host. The MR52 Series 2 & 3 SIO 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 Series 2 & 3 SIO.
