MR52 Module Setup

1.0 Introduction

 

MR52_S3
              Series 2 MR52 Module                   Series 3 MR52 Module

 

 

The MR52 is a dual card reader interface panel with on-board flexibility to connect a wide range of security devices. The MR52 is easy to install and provides the required I/O for interfacing two card readers, eight general-purpose input monitor points and six control relays to any Authentic Mercury series intelligent controller

 

With two-wire RS-485 connectivity, the MR52’s two reader ports support OSDP, OSDP Secure Channel, keypads, biometric readers, Wiegand, clock and data, magnetic stripe, F/2F and supervised F/2F reader technologies. System configuration and setup are provided through Mercury OEM partner software applications.

 

Note: Series 3 Mercury modules are fully compatible and interchangeable with Series 2 modules.

 

 

2.0 Hardware Configuration

2.1 Power Supply to the MR52

The MR52 module accepts either 12VDC or 12VAC for power. Locate the power source as closed to the interface as possible. Make power connection with minimum of 18AWG wires. The input voltage is filtered and regulated to 5VDC or 12VDC.

 

 

 

2.2 S1 DIP Switch Settings

  1. The MSC-MR52 has a DIP switch (S1) - this is used to set the address of the module. Switches 1 to 5 select the device address. Switch 6 and 7 select the communication baud rate (the default baud rate for MSC hardware is 38,400). All other configuration settings are set via host software.



  2. The MSC System Processor Module (i.e EP1502) is automatically assigned address 0 - You can see this if you enable Advanced View in the controller properties and look within the Miscellaneous section.



  3. If the MSC-MR52 is the first module on the RS-485 network you would therefore set S1 to address #1.
  4. The MSC-MR52 module communicates to an MSC controller via the RS-485 communication link (TB6 connector) The interface allows for multi-drop communication on a bus of up to 4,000 feet (1,200 m).
    The RS-485 interface can be set for either 2-wire or 4-wire configuration via the J3 jumper. By default J3 is set to 2-wire.



 

 

3.0 Setup Procedure

  1. To add an MR52 to the system you must already have an MSC controller (EP, LP or MP) added and online in the software. In the following example, the MR52 is being added to an LP-1502 controller.



  2. Expand the controller on the hardware tree, then select either the TB2 or TB3 entry.

    Note: Some MSC controllers only have a TB2 port.

  3. Click the MR52 icon from the SCP hardware select ribbon, if you are adding a series 2 module.

    MR52 Icon

  4. Or click the MR52-S3 icon located in the Mercury Security hardware select ribbon, if you are adding a series 3 module.



  5. A dialog box will appear stating the exact model (MR52) - you also have the option of adding multiple DDMs but it defaults to adding 1 module.



  6. Click ACCEPT and the MR52 module will appear beneath the controller in the hardware tree.
  7. If the MR52 is configured and wired correcting it should immediately come online.



  8. You should also see events for the MR52 in the Live Events grid.
