Mercury Security MR51e Installations And Specifications

MR51e Reader Interface
Installation and Specifications
1. General:
The MR51e reader interface provides a network connected interface to one physical barrier using single
or paired reader. PoE based solution to the OEM integrator for interfacing TTL (D1/D0, Clock/Data),
F/2F or RS-485 readers to door hardware. The on-board twisted pair Ethernet jack with PoE support
enables easy installation.
control for one physical barrier.
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 UL294B.
Reader port 1 can accommodate a reader that utilizes TTL (D1/D0, Clock/Data), F/2F, or RS-485 device
signaling and also provides tri-stated LED control, and buzzer control (one wire LED mode only).
Reader port 2 can accommodate a reader that TTL (D1/D0, Clock/Data), or F/2F signaling, and also
provides tri-stated LED control, 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 that may be used for monitoring the door
contacts, exit push buttons, and alarm contacts. Input circuits can be configured as unsupervised or
supervised. The MR51e requires PoE or local 12 Vdc for power. 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.
