MR51e Reader Interface
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.
