Installation and Specifications

1. General:

The MR51e reader interface provides a network connected, single door with paired reader, PoE based solution to the OEM integrator for interfacing TTL/Wiegand/RS-485 type readers to door hardware. The on-board twisted pair Ethernet jack with PoE support enables easy installation.

Note: For UL, the Power Sourcing Equipment (PSE) such as a PoE enabled network switch and/or PoE

power injectors must be UL Listed under UL294. One physical barrier can be controlled with the MR51e, using single or paired readers. The first reader

port can accommodate a read head that utilizes Wiegand, magnetic stripe, or 2-wire RS-485 electrical signaling standards, one or two wire LED controls, and buzzer control (one wire LED mode only).

The second reader port can accommodate a read head that utilizes Wiegand or magnetic stripe signaling, one or two wire LED controls, and buzzer control (one wire LED mode only). Two Form-C relay outputs may be used for door strike control or alarm signaling. The relay contacts are rated at 5 A @ 30 Vac/dc, dry contact configuration. Four inputs are provided for monitoring the door contacts, exit push buttons, and alarm contacts. The MR51e requires power from PoE or local 12 Vdc. The MR51e may be mounted in a 3-gang switch box; a mounting plate is supplied with the unit. The MR51e may be mounted in an enclosure; the supplied mounting plate has mounting holes that match the MR50 mounting footprint.

3. DIP Switches:

The addressing mode used is determined by the DIP switch setting on the MR51e:

Notes:

 Public DHCP and Static IP Addressing Modes are available with MR51e firmware

revisions 1_4_2 and later

 All other DIP switch settings are reserved for future use  Press S2 to reset board after DIP switch is changed for new address mode

4. Input Power:

The MR51e is powered by one of two ways (jumper selected):

 Power is supplied via the Ethernet connection using PoE, fully compliant to IEEE 802.3af  Or local 12 Vdc power supply, TB5-3 (VIN), TB5-4 (GND).

5. Communication Wiring:

Communication between the EP controller and the MR51e is Ethernet. (10Base-T/100Base-TX)

6. Reader Wiring:

The first reader port supports Wiegand, magnetic stripe, and 2-wire RS-485 electrical interfaces. The second reader port supports Wiegand and magnetic stripe electrical interfaces. Power to the first reader is 12 Vdc and is current limited to 150 mA. The second reader may be powered from the auxiliary power output on TB5-1 and TB5-2. Readers that require different voltage or have high current requirements should be powered separately. Refer to the reader manufacture specifications for cabling requirements. In the 2-wire LED mode, the Buzzer output is used to drive the second LED. Reader port configuration is set via the host software.

When powering any remote device(s) by the MR51e, care must be taken not to exceed the maximum

current available. Cable gauge must also be evaluated. See specifications section for details.

7. Input Circuit Wiring:

Typically, these inputs are used to monitor door position, request to exit, or alarm contacts. Input circuits can be configured as unsupervised or supervised. When unsupervised, reporting consists of only the open or closed states.

When configured as supervised, the input circuit will report not only open and closed, but also open circuit, shorted, grounded*, and foreign voltage*. A supervised input circuit requires two resistors be added to the circuit to facilitate proper reporting. The standard supervised circuit requires 1K Ohm, 1% resistors and should be located as close to the sensor as possible. Custom end of line (EOL) resistances may be configured via the host software.

* Grounded and foreign voltage states are not a requirement of UL 294 and therefore not verified by UL.

The input circuit wiring configurations shown are supported but may not be typical:

8. Relay Circuit Wiring:

Two Form-C contact relays are provided for controlling door lock mechanisms or alarm signaling. The relay contacts are rated at 5 A @ 30 Vac/dc, dry contact configuration. Each relay has a Common pole (C), a Normally Open pole (NO) and a Normally Closed pole (NC). When you are controlling the delivery of power to the door strike, the Normally Open and Common poles are used. When you are momentarily removing power to unlock the door, as with a mag lock, the Normally Closed and Common poles are used. Check with local building codes for proper egress door installation.

Door lock mechanisms can generate feedback to the relay circuit that can cause damage and premature failure of the relay. For this reason, it is recommended that either a diode or MOV (metal oxide varistor) be used to protect the relay. Wire should be of sufficient gauge to avoid voltage loss.

Diode Selection: Diode current rating: 1x strike count Diode breakdown voltage: 4x strike voltage For 12 Vdc or 24 Vdc strike, diode 1N4002 (100V/1A) typical.

MOV Selection: Clamp voltage: 1.5x Vac RMS. For 24 Vac strike, Panasonic ERZ-C07DK470 typical

Relay Circuit Wiring (continued):

It is possible for the MR51e to provide power for a 12 Vdc door strike providing the maximum current is

not exceeded, see specification section.

9. Status LEDs:

At power up, LEDs 2 through 6 are turned ON then OFF in sequence. After the above sequence has completed successfully, the MR51e goes to the “Waiting for IP Address”

mode, when in the MSC-Specific DHCP or Public DHCP addressing modes: Waiting for IP Address mode:

The following table describes the LED’s in the Normal Running mode. If communication is lost, the MR51e reverts back to the “Waiting for IP Address” mode, when in the MSC-Specific DHCP or Public DHCP addressing modes:

Normal Running mode:

Note 1: If this input is defined, every three seconds the LED is pulsed to its opposite state for 0.1

second, otherwise, the LED is off.
