This Quick Start Guide is intended for experienced installing technicians. It is a basic reference to ensure all connections are properly made. 
Models include EM-30, EM-50, and EM-64. For additional information please reference Farpointe Data’s website, www.farpointedata.com.

1.0 Introduction

A key component of a physical security electronic access control 
system, a proximity card reader is based on RFID technology. In 
operation it is capable of reading data stored on a proximity credential 
via radio frequency and without physical contact, and then passing the 
data obtained to the physical access control system. Access control 
systems typically manage and record the movement of individuals 
through a protected area, such as a locked door.

2.0 Mounting Provisions

Each reader may be installed either indoors or outdoors. Mounting 
options shown in the table below. Use supplied #6 mounting screws, 
or equivalent security screws, for installation.

WIRING NOTES:

a

Single Line LED:

 This is the standard operating mode and does not make use of the 

Orange conductor. The LED is Red when the reader is idle and flashes when a card is 
presented. The LED turns Green when the Brown Conductor is pulled low by the access 
control panel.

b

Dual Line LED:

 This mode makes use of both the Brown and Orange conductors. The 

Brown conductor controls the Red LED and the Orange conductor controls the Green 
LED. LED states are determined by the access control system option and capability.

Unused conductors should be trimmed, isolated and taped back to prevent unintended 
current flows. Apply positive voltage only to the Red DC Conductor.

4.0 Cable Requirements

24 AWG minimum, multi-conductor stranded with an overall foil shield, 
for example Belden 9535 or similar, supporting the five conductors 
comprising the physical layer of the Wiegand interface (power, ground, 
data 0, data 1, and/or beeper and LED). Alternatively, Belden 9539 or 
similar, for all reader functions. Contact your access control system 
manufacturer for their specific requirements. Per the SIA’s Wiegand 
specification, maximum cable length is 500 feet (152 m).

5.0 Output Formats

Wiegand (industry standard 26-bit Wiegand and  
custom Wiegand formats).

6.0 Grounding

Shield (drain) continuity must run from the reader to the access panel. 
Shield (drain) and reader ground must be tied together at the access 
panel and connect to an earth ground at one point.

7.0 Power

Reader may be powered by the access panel. A linear power supply is 
recommended for best operation.
 

8.0 Voltage and Current

Voltage: 5 to 16 VDC
Current Draw: 70mA to 110mA

9.0 fleaPower™ Control Line

To reduce the average current required by the reader,  
pull the purple conductor low.

10.0 Connection

Connection must be done in accordance with NFPA 70. Do not 
connect to a receptacle controlled by a switch. Connect to a power 
limited DC voltage source.

11.0 Troubleshooting

1.  When the reader is first powered on it will beep 4-times,  

and the LED will shine red.

2.  Presenting a supported access credential will result in the  

reader beeping and the LED flashing once.

NOTE: The access panel controls LED functionality,  
such as switching the LED to green.
